Diesel Day Dream?
 

I Have A 42 Fountain Less Power/drives.thinking About Twin Marinized Duramax,procharger Air To Water Intercoolers,shorty Powerglides With Tight Converters To Asd8.getting The Right Prop Will Be Hard ,but What Other Problems Can You Come Up With?

where do you get marinized duramaxes? is there enough room in there to fit all that?

There's alot more stuff and power to be had for the 5.9 B series Cummins. These have been used in marine applications for along time now. They are 6-7 inches longer than a BB and only 150lbs more or so. 5-600hp would be real easy, but the torque would be through the roof, 8-900ft/lbs. You would have to change gear ratios and still run a huge prop. I have been thinking about this setup for my Scarab.

I Thought About Cummins,but The Duramax Revs Faster(short Stroke),sounds More Like A Bbc,and Has Bbc Bellhousing Pattern.shorty Glides Are About 24" So Should Have The Room To Move Motors Forward.as Far As Marinized Duramax Parts I Have Heard Of A Coulple Places That Do It, But I Have Not Heard Back From Them.worst Case I Would Run Them With No Hatches Or Ele. Fans Big Scoops And Lots Of Vents With Watercooled Exhauts Extenions.

MARINE TECH 6.6 DIESEL UPDATE

The 419 HP and 550 HP models of Marine Tech’s revolutionary GM 6.6 liter Turbo Diesel engine, presented at the 2007 Miami Boat Show, are now complete. This ground-breaking engine weighs 1300 lbs., making horsepower equivalent to 1,700 - 5,000-lb. diesels. Additional benefits include:

419 HP version at 711 ft. lbs. trq. at 3,100 rpm., and 550 HP version at 826 ft. lbs. trq. at 3500 rpm
Dimensions are 38” wide X 39” long (with bell housing & oil coolers) X 42” tall
Longer life span than gas engines, with a life expectancy of 3,000+ hours
Greater fuel efficiency, averaging 27-30 US ghr.
Increased safety, programmed against operator error or abuse
Extreme oil cooling
3-stage raw water pump to cool the Freshwater Cooling System

Another plus is you can run farm diesel (avoid the taxes) for around $2.00/gallon....If you have access. I've never heard of them dipping
marine tanks for colored fuel.

I saw these at the Miami Boat Show and I am VERY impressed with what I saw. I spent a LOT of time studying them. At that time they had a few things to finish up on cosmetic wise, but I really hope this company takes off and grows, as I feel they have a dynamic marketable product with a great engine at the right time. I can't say enough good things about what I saw and heard. Phenominal comes to mind...

Actually, I kinda wish I could become a dealer for them...

You don't think 1300lbs each is too heavy for most twin engine boats?

A Dressed Out Big Block With Blower And Intercooler Is Around 1100lbs.
