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

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.

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.

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

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

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.

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.

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
