prochargers good or bad
 

What is wrong with putting a procharger on a boat engine?

What is the differece between putting a procharger on or just modifying the engine in a different way for more power.

I read all the time here that guys are changing things to the engine to get more horse power, but have not heard anything good about adding a procharger.

I am new to this area of boating and the used boat I bought in oct of 2010 has a m1 procharger on it.

Everyone has an opinion. I would consider doing a roots type (Whipple) for example to be more reliable. Personally, I view all of them as time bombs. There's a lot more to it than bolting on a "blower" and mashing the throttles. Some engines are good candidates for supercharging and some not so much. Then you need to have outdrives that can handle the extra power. Some hulls respond better to throwing power at them better than others.

A lot of people in this hobby enjoy engine building, chasing a speed goal, racing, etc. I enjoy going fast as well, but I'm a bigger fan of stock reliability. For me it's stock black motors and family fun on the water. For the next guy it's helmets, Life Line jackets and breaking the 150 MPH mark. To each their own.

I don't see anything wrong with it but if I force feed my 525 in the future it will be with a Whipple Charger :).

Just to be nitpicking a bit. The whipple is not a roots style sc, but a Lysholm/twin screw. They are quite different, and deliver boost in quite different ways.

Anyway regarding the question. SC's deliver other things than power. One of them is heat, which if the motor is not build properly, will ruin the motor. This is also why the 496 in stock form is such a bad choice to boost, but then again, it's a bad choice for tuning, if you don't change the internals to forged parts, even if you do n/a tuning. The centerfugal sc's is the least efficient sc's out there. They develop as much heat, if not more than a roots blower, they have an efficiency below 70% and take a long time to spool up. They are cheap though. The only application that works well, when using centrefugal compressor, is when turbine driven. As many know, turbos are very efficient, but takes some knowledge and time to set up in a boat. If you want to run forced induction, you need to build the motor to handle the boost, but also the fuel system, cooling system, drive line and steering ect. right for it as well. Anyway as Baja 342 suggested, go with a twin screw sc like fx. the Whipple.

I have a friend that bought a boat back in 2000 that had twin 454's with procharges. He has run the boat hard every year. Motors are still going strong. Has torn up 1 outdrive in all these years.

If they are set up right they will run great and live a long life.

procharged 540
 

I am putting a 540 with procharger in 04 25ol. Schumaker built the engine right from top to bottom 4 years ago and engine has been great. 800hp/800lb. I like the power curve of the procharger, just keeps pulling

I have a M3SC kit for sale, very very low hours as it never made a full day of running without shreding a 150.00$ belt or braking off the front of the motor poping and pissing!
Give me a roots blower any time (letts play all day).
The projunk made 14 lbs and went 96mph 1 time the roots makes 6lbs and runs 94mph ALL DAY its just a pully change away!!!!!!!!!!!!!!!!!!!!

thanks for the info
 

Thank you for the information. I will read the web site. I wanted a bigger boat that did at least 60mph. I found this one oct of 2010. bought it at, i thought a good price. The man i bought it from only owned it to years and used it 5 times. he new nothing about the boat except how to put gas in it. I talked to the originally owner and he gave me back ground info on it.

The boat is a 24 ft 1997 outlaw sst, wiith a 502 mag ho (2009) converted to carberated, m1 procharger 2007 , extra hollie fuel pump (2 fuel pumps on boat), a high performance manifold I believe he said, some extra high performance parts, 4 blade custome spinellie prop, made and tweeked for that boat. He had everything done by a marina or a professional in the field

I am going to take it to a racing shop to have it dyno test, and make sure it is set up correctly. This race shop works on high performace boat engines. They are also going to put a rev plate on it or a msd box on it for me,

I am trying to learn as much as possible about this new hobbie. I am a recreational boater. But I like to go fast once in a while. not into racing or abusing the boat. I am a perfectionist when it comes to my stuff. Just using it for enjoyment and to enjoy a speed rush once in awhile.

My mechanic and i had it up to 78mph, the original owner said it would do 80mph - 85mph with the trim up all the way. At 78 mph we had alot more trim to move , as well as trim tabs, but it danced alittle, So this spring i am putting imco add on hydraulic steering arm on it. It came with a side winder arm .
I think I have typed to much so , so long , and thanks again

thanks
 

i boat the boat with the m1 procharger, so it is what it is. thank you for positive feed back

thanks for info
 

How do i know if the engine is properly built for it? Will a race shop with a dyno machine tell me everything? I am, taking it there in the spring, it is a 502 mag ho (2009) turned in to a carberated with high performace manifold, m1 pro charger, two fuel pumps and , a spinelle prop

thanks for the info
 

thanks for the info, on other threads, all i heard were terrible things about these superchargers, it has a m1 procharger

power
 

I did notice the pull when hit the throttle , it was a nice feeling. This plenty enough power for me

procharger
 

I read the article, and looked my unit up online. From my novice experience and lack of motor knowledge. The oneI have seems to be a safew choice for me.
if you have time could you take a look and tell me your opinion.

The site is: http://www.procharger.com/marine/M_t...imonials.shtml

It sounds like a decent one. It was already on the boat when I bought it. Please give me your opinion it is m1

thank you

I am not an expert in engines. My opinion would get you a cup of coffee, along with $2. I've read that before. quotes like “I like it. It’s really a good, easy bolt on” are what scare me. I don't view superchargeing in any from as a way to prolong an engine's life, quite the opposite. Therefore they do not intrest me.

I ran a ProCharger M1 with 3lbs of boost for over 200 hours on a 496Mag.... never had a single issue.... went from turning a 24 Bravo at 5000 to turning a 28 bravo @5000 ....easily 10-12 mph gain.... no loss of fuel mileage under 4000 rpm's.... no change to the mannerisms of the stock 496... done right its the best $5000 you can spend for 10-12 mph imo....

I bought the boat with it. I would of not went and bought it on my own. it did say about keeping the engine cooler then the other types of chargers. It seems to me that it is a milder version of a chargre, less potential for problems, and helps the egine run more effeicent

Thanks for the positive feed back. i hope the original owner did it right. I am going to have a race shop check it in the spring for me. They will also tell me everything else done to the engine so i have a better understanding of yhe whole set up, and know what i have under the hatch

your boat
 

you have a nice loking boat, do you have more pictures?

sorry for repeated thread but my computer was acting up

Thanks! It's not bad for a cruiser:) I flirt with 70 MPH.

very nice looking boat, very big too, hate to be at the gas pump with u. i am happy with my boat just trying to find out as much as possible about the engine. to bad the guy i bought it from knew nothing, and i had to contact original owner to find out stuff, he said the boat will do 80 mph all day that is fast enough for me, at least in a boat you can use the speed not like a car except going aroun d a track

fastest i have had mine up to was 78 mph, with the mechanic, he said it had more trim to come up and we could play with the trim tabs too and it will definitly do 80, so the original owner wasn't lieing about the speed, i saw the speedometer at 78, but the back end was walking around alittle, so 80 to 85 is dueable, not that i will be doing it all the time

Sounds like a sweet boat you got!!

I love my Prochargers!

Since you already have the boat just maintain it better then normal and you will be fine. IMO a supercharged engine askes for more out of the engine so just treat it better.

Simple...

Let it warm up before running hard, apply the power smooth and un-apply it smooth also, let the engine cool down before turning it off. Change the fluids more often with higher quality oils and filters. (aprox every 20 hours).

Agreed, you must upgrade to dual hydraulic steering.

Change your drive fluid more often with quality fluid like the bravo shop oil. You will eventually need to upgrade drives.

I turn a TON of HP with my prochargers. I have NEVER lost a belt, even after running 50 hours in a summer! A supercharger is a supercharger, any or them set up good or bad will be good or bad.

Nothing beats a turbo though. Thats why all Semi's use them, all diesels, and pretty soon all Mercury engines! LOL!

But since you and I already have prochargers lets enjoy the Chit out of them!

WOW! I like!

Your boat looks a lot better in these pics then your avitar, but then again my cheap azz non paying member can not enlarge your avitar!

Thanks guys. You run ahead, find a good spot to tie up and get the beer cold. Ill catch up eventually:)

setup, setup, setup.

make sure setup is correct. Fuel system is correct and then sit back and enjoy.

thanks
 

Thank you for the info. I will definitly take extra csre and make sure my mechanic is keeping a better eye on it. I always had my old boat serviced twice a year, winterized and summerized, and didn't spare any expense to taking care of it. If you have any other good advice, please send it my way. I am new to this type of boating and am glad to get any good advice.

thanks

jj

thank you
 

I will do all of the above. I am going to take it to a race shop in the spring to make sure everything is up to snuff and find out how to take care of it better. Thanks for the info, any other comments , i would be glad to read

thanks

jj

thanks
 

I will definitely be babying the boat. I won't be racing it. Just going fast once in a while.

famous last words.....

Yea cheap ass pony up. Quit saving your money for bikini's for Kristy she doesn't need them.:party-smiley-004:

Your right! What a waste of money isn't it???!! Think of all the boat parts we could buy if she just stops wearing bikinis! LOL!

:evilb::worthless_without_p

Interesting thread... good luck with your boat.

I repowered last summer with a 600 Hp Custom 496. During the upgrade I reasearched the hydraulic steering to death and decided to go with a FULL Hydraulic twin cylinder system. Got a good deal from Bill at Diamond. I went with IMCO after talking to Mr. Inman about the differences between add-on and full. My main concern was safety, and there is still slack and potential safety issues with a cable activated hydraulic system. Also the twin cylinder is more consistent when turning from side to side. With a single cylinder you have the full cylinder diameter pushing the drive to one side and then the full cylinder minus the rod diameter pushing it back the other way. It's about a 50% difference. Anyway, my boat drives like it's on a rail, holds the wheel position in a turn without any effort and took the drunk walk out of it at an idle. I had others tell me how much difference it would make, but until you drive it, there's no comparrison.

AS far as belts go, I have shredded quite a few but I am turning my Procharger well past its rating and thats when the problems started. I cant stand to drive a boat anymore that doesn't have hyd steering and serious power, it just feels sooooo slow!! As far as "not racing" people, I can't see having a blower motor in a boat and not stretching its legs against all the people that claim to have fast boats:evilb:
