Turbo Diesel Powered
 

Anyone have any experiance with one set up in a go-fast boat?

With gas prices at over $2.00 a gallon and diesel technology as far as it is, this seems like a nice option.

I was just on the Genesis-skier web site and they offer their new 30'er with a turbo diesel option.

Sure would sound different!!

Re: Turbo Diesel Powered
 

It would be great, 10,000 hours before a rebuild, 5-6 mpg, less $$ per gallon...but, the cost of these is huge and you would need to keep the boat a long time to pay off. It has been done and works, just not in a financial way for most. I paid the extra for my Excursion but that is driven every day and will be a keeper.

Re: Turbo Diesel Powered
 

I have one in the Super Duty also and love it!
Worth every penny of the $3000.00 upcharge.
Would it be much more $ in a boat?
I guess finding a Mfg. that has experiance doing it is half the battle.

Re: Turbo Diesel Powered
 

I have a powerstroke diesel. It makes about 350hp, and 750 ft/#'s. Would that bee too much for an outdrive? I believe that it would tear up a bravo drive very quick. Also my diesel wont spin past 3400 rpm.

Re: Turbo Diesel Powered
 

Yanmars have been done in Donzi's (I think it was a 33.. 60 MPH equaled a 21 GPH burn.. ) and Spectres (Yanmar again, 95 MPH no problem) and maybe Sonic's.. Very doable, they just don't "sound" right at the dock LOL

Re: Turbo Diesel Powered
 

...and Hustlers. A 388 Slingshot with twin 440 Yanmars and Arnesons will do 83 mph and run 75 all day. The new "Esprit de Soleil" which is 50' x 10' and 23 000 lbs. dry will do 80 mph and cruise at 70 all day. At economical cruising speed of 60 mph, it will have a range of over 650 NM on a 500 gallon fuel tank. It has four Yanmars and Trimax surface drives with ZF 2-speed trannies. The combined torque of four diesels is 3200 lb-ft so this thing comes on plane in under 4 seconds and will accelerate past 60 in under 10 secs. Incredible for such a big boat with 6'10" of cabin headroom. Also, due to that torque, you can load the boat with 15 people without any major effects on performance. And in the rough stuff, with the sheer mass and the torque, it will pound through anything. Diesels have load governors which keep the RPMs constant no matter what the load on the prop is. There is no need to throttle, just pound through the waves. They will never sound like V8s but great stuff nonetheless. And think about few thousand hours b/w rebuilds. I've got 1300 hours on mine with only routine maintenance and it does not look like I'll have to take them apart anytime soon...

Re: Turbo Diesel Powered
 

super termoli what are you running those diesels in?
Nothing speaks like experiance.
I'm looking to have a set up done in a single engine application.

I don't know about the Yanmars, but the shop next to mine, Huckstorf Performance Diesel, tells me 450-550 HP w/800+ lbs. of torque out of a truck engine is no problem and the reliabilty is still very much there.

Re: Turbo Diesel Powered
 

I'm running four Yanmar 440s in this. It's 50' x 10'. But to be honest, if you're looking at a single application for a smaller boat, Yanmar is probably not the best choice because they're long and narrow so you're likely to run out of engine space. You also need to factor in the trannie because a Bravo will not take the torque. You need to step up to an Arneson ASD8 or something like that.

To use a Bravo, you need to step down to a Yanmar 300 as even the 370 has too much torque in my experience.

However, what could be a solution for you is a marinized GM V8 6.5. Marine Diesel have it up to over 400hp. with a Whipple charger I believe. I hear they're pretty reliable. The V8 design means a shorter engine which will leave more room for a trannie should you need to turn away from a Bravo. You could probably run that with a new ASD6 where the trannie is located in the extension box just off the transom. It's a pretty easy retrofit on a Bravo-style boat... So I hear, I've never done it...

Re: Turbo Diesel Powered
 

oops, the photo didn't attach. another try...

Re: Turbo Diesel Powered
 

The Genesis I'm looking at runs a turbo diesel with a V-drive. I'm guessing that is due to weight.
That's quite a boat you have there, are your Yanmar's running turbos?
What a sound that must be!
I'd take that over a screaming blower motor, that roar gets old when cruising.

Re: Turbo Diesel Powered
 

super termoli could you point me toward someone who's more knowledgeable on this type of work?

Re: Turbo Diesel Powered
 

Merc does offer a diesel with the bravo. I believe that is made by Cummins.

Re: Turbo Diesel Powered
 

Hi Cord, it's been a while. I still would like a ride in that Firehawk some day.
Maybe I'll see you at the races. I'll be in the dry pits again.

The Bravo will not handle what I'm planning on throwing at it.
When I dive into this it will have to be a surface drive or a v-drive, once I hear how that worked out.
I'm worried about the weight, so to offset that the diesel would be in the 500HP range, but you can figure on almost triple that on torque rating.
I wonder how foamy the diesel fuel gets while sloshing around on a choppy lake.

This should be different:)

Re: Turbo Diesel Powered
 

Chad-we will be down there. I managed to snag a spot as a patrol boat, so look for us on the water! If you see us, flag us down and you'll get your ride.

Weight is a big issue with these engines. My 5.9 Cummins weighs 1,000lbs undressed. A big one like you are talking about will be close to 2,000lbs. If you have the coin, I did come across a freshly rebuilt V-16 the other day. Maybe it was a V-12, I don't recall. You should be in the 1,000-1,500 hp range with that engine. $14,000 complete. That would be really cool in a heavy V like a Apache or somthing as a single. I would think that a ASD-8 would survive with that power.

Re: Turbo Diesel Powered
 

the guys that make the diesels for Hummer make a diesel for conversion like 400 hp from gm 6.5!!!Drive breaker for sure...a couple Konrads would fix that!!

Re: Turbo Diesel Powered
 

Your 5.9 can be bumped to 450HP VERY easily, it's the tranny that is weak on those Dodge trucks.
Call Huckstorf and chat with them about options on it: 414-421-7222 talk to John, they are very, very nice people to deal with. Then you can stop next store and say hi to ME :D

Re: Turbo Diesel Powered
 

hi.
I have marine diesel in my boat. a hammerhead 300hp and bravo one drive. have run the engine 200 hrs since i bougth it last summer.

diesel is cheap and reliable.

Here is some pics of a nortech 50 cat with 4 yanmar 420`s tuned up to 470 hp. It was raining the day we where out in her, so the pics is not the best quality.

Re: Turbo Diesel Powered
 

some more pics of her.

Re: Turbo Diesel Powered
 

You gotta be kidding me! I had my truck down there last week for a idle problem! It reoccured so I had to go back. They describe me as "the white truck with the radical pump"! :D

The CTD made 370hp from the factory in a marine app. There is no reason why it can't make more than that in a street app. Hucks estimates my crank power at around 450hp. I know that there is at least another 75hp in it with out getting too expensive.

Re: Turbo Diesel Powered
 

Wow years back we had the work-up on a little 10 Meter Diesel Cat open fish the point of it; Was the 6.6 MPG @ 58 MPH Cruse and 70+ top in those days the Arabs were begging to sell Oil at $11.00 a Barrel so it got shelved..

Re: Turbo Diesel Powered
 

Seems that Arnesons with a strong turbo diesel is a consideration.

Re: Turbo Diesel Powered
 

Our parasail boats go about 10,000 hours before the volvo Pentas we run wear out. Supercharged and Turbocharged for low end and high-end power. The SC runs on a clutch like an AC compressor so its only on at low-mid RPM. I don't think you'll find too many big-blocks that last 10,000 hours, most of the guys running gas motors get a new one every year and burn 2-3 times the fuel we do.

Re: Turbo Diesel Powered
 

I've been calling around and cannot locate anyone who has installed a single engine diesel in a performance application......yet!

Like jtmiller said: 10,000 hours before they rebuild 'em. I'd be happy with 2000 hours!!!
Someone has got to be doing this, or willing to try.

Re: Turbo Diesel Powered
 

Custom.

Falls into the custom category. Custom equals money. Unless you plan to do a lot of this work yourself, prepare to shell out $$.

Marine diesels are big bucks. My cruiser had Mercruiser Horizons as standard power. Cat diesels were a $38,000 upgrade. I got em. Would do it again in a heartbeat.

What's different about the boat in a diesel app? Fuel tanks need returns plumbed into them. A fuel cooler on the return line is a good idea.

I don't know of any "short" marine diesels. A V8 conversion as has been mentioned would be the shortest option. You'll need a healthy heat exchanger and great big ole raw water pump and transom mounted water pickup. My 350hp Cats use 2" raw water lines and flow huge amounts of water. I believe the 660hp motors I've examined use a 3" inlet. That's big stuff.

Diesels don't put out much carbon monoxide. They don't tend to explode. Both are nice attributes for boating.

god luck

Re: Turbo Diesel Powered
 

The "Big truck diesels" you speak of at 500 hp will be between 1600 and 1850 ft lbs of torque and weigh closer to 3,000-3,500 lbs each !! WAY TOO BIG AND HEAVY ! YOu need small , light weight stuff. Seatek's maybe ?? Don't know a thing about them , maybe super T. can shed some light on them . The Mercruiser V8 diesel is actualy the Navistar engine or better known as the ford power stroke in a truck .... 350 hp stock . You will need 2 speed trannys and a good drive . The Konrad may work too.

Cord, What is done to yoru dodge to get 450 hp ? by the way , you get those "things" yet ???? Joe

Re: Turbo Diesel Powered
 

We use these...not a huge amount of power but unique to say the least and very effective for our application. Our boats are made by premium and are about 29ft i think. Something with a little more power would be pretty nice, I'm sure anything too much bigger would be to heavy in this size range of boat.

Re: Turbo Diesel Powered
 

Yamaha had some nice Marine Diesels the 420 Hp they were claiming like 25000 hours.

Re: Turbo Diesel Powered
 

Diesel engies are way big in europe.

up in scandinavia 90 % of the boats that are built are diesel applications.

if you are satifyed with speed up to 60 miles/hour.

yanmars on bravo drives.
volvo penta cad 43 dp 290
steyr 256/260 bravo
marinediesel bravo or other drives

are way to go.

and since commonrail engines are popping up like pocorn.
the future will see more of these engines go in to the marine marked.

several of these engines are high rpm diesels.
example
steyr 4500rpm wot.

iveco is now comming with a light weigth engine
390 hp at 4400 rpm

yanmar 290hp is modified to pump out 400hp at 4600rpm
by several companies up here in Scandinavia.

marinediesel has a 400hp v8 wich will fit in a standard v8 mercruiser or volvo application with no modification at all.

I have my self a marine diesel hammerhead 300hp in my boat.
a cobra 28 centerconsolle. It has 24" deep vee and weighs 2500 kg/ 5500 pounds

top speed with a singel engine is 50 miles hour.

last year I had 100 hrs on the engine. And used aprox 400 gallons of diesel.



A friend of mine has the same boat with a yanmar 290 modified to 350hp
his top speed is 59miles.




in provee racing they use singel engines, seatek engines. Last weekend we had provee racing where I live, friday they had speedtrail. and the top speed was set by
welmax. a fabio buzzi design boat. the top speed was aprox 109 miles.

Re: Turbo Diesel Powered
 

I Have!

Did a single a couple of years back as a tester, then built this twin.

My Phantom

Or Here

Over here there are a few builders who put single diesels in sports boats such as:

www.extremepowerboats.co.uk

and

www.sportrib.com

Re: Turbo Diesel Powered
 

Here you go: Currently out in a 310 hp version, but available this fall as 370 hp/1649 lbs complete, no transmission required (drive shifts), all fly-by-wire throttle and shifting, and commercially rated: Volvo Penta D6-310/370 DPR

Re: Turbo Diesel Powered
 

Volvo certainly is making some progress but still nowhere close to Yanmars, especially as these will be bumped up to close to 500hp. when they become electronically controlled. Secondly, those drives will not last in high performance applications. They already have a dubious reliability record with 310hp. and even with 285hp. of the KAD300. And this is on cruisers doing 45 mph max. Imagine now putting them on something capable of 60+ and light, meaning frequent launching off waves... No hope guys, forget stern drives with diesels and big torque...

Re: Turbo Diesel Powered
 

cool

Re: Turbo Diesel Powered
 

Super - Are you aware that the DP-R drive coupled to the D6 engines is totally new and way bigger that the current series of drives?

The real answer here is 40% overdrive gears between the engine and the drive...

Re: Turbo Diesel Powered
 

Yep, I know. It's just that my experience has been terrible. I had the misfortune of running KAD44s with DP and it was a drive disaster. Then I was dumb enough to have KAD300s on a Cranchi 39 and guess what? Drives kept on causing me grief. So, I may be a bit harsh but once you disappoint, it's hard to climb back up that hill. Engines themselves are great, it's just the drives that suck. And I don't think it has much to do with Volvo. It's just that the whole Z-drive concept is getting old.

Re: Turbo Diesel Powered
 

Question Super T. :) If you say have a boat like a 4300 that does 67-70 w/triple 315 yans and Arnesons, and about the same speed with twinn 440 yans, what would be a better way to go. What if you put a stern drive on like from Weismann vs a surface drive from Arneson. I'm uncertain of getting on plane as well as docking with Arnesons, both are extremely important to me vs 1 extra mph, these are just Q's that I have from inexperience or what I have read on the board. Would the stern drive be faster or slightly slower. Thanks Jeff

Re: Turbo Diesel Powered
 

Well the volvo dpr drive is way much bigger than the drives you had on your kad 44 or kad 300. it look like the volvo dp drive but physical messurement is way much bigger. and heavyer.

the sterndrive on volvo d6 weighs aprox 220 pounds
a sterndrive on volvo kad 43-44-300 weighs 130-140 pounds.


I am personally not a fan of volvo engines exept for the kad 43.
after you have done a little tune up job on the diesel pump and put a manual switch on the compressor. Then it pumps out 250-280 hp, instead of 216 hp.

Re: Turbo Diesel Powered
 

What has to be done to pump up a 315 Yanmar and a 440 Yanmar. Whats all involved to add another 40-70hp and do it safely, thanks Jeff

Re: Turbo Diesel Powered
 

What's the deal with the first pic in post 18. Why is the far starboard tach @0. Its still making boost so it must be running.???

Re: Turbo Diesel Powered
 

One would think, given the info you've pointed out, that the tacho is F****d!

Re: Turbo Diesel Powered
 

How reliable are Seateks. I know off the web site they can be serviced by Innovation Marine in sarasota. What is the life expectancy of say their 750 hp or even their 850 hp, 5000 hours or more, Thanks :) Jeff
