I have heard that Ford is wanting to get back in the marine industry. They don't seem very committed. I'm not sure if this is it. But being at SEMA might make sense to announce that Indmar is switching back ?

Hmm. Ecoboost?

I'm thinking the turbos would generate too much heat under the engine box, but an Ecoboost marine engine is interesting.

GM is no longer making the 5.7 in an iron block. aluminum everything.

GM is actually still making the Iron Block 5.7 in Mexico exclusively for the marine industry. They will for 2 more years.

It seems strange that Indmar is switching to Ford from GM. Ford offers only the 5.0 and 6.2 in V8's.
The 5.0 is all aluminum and the 6.2 is Iron Block with Aluminum heads. As wide as that Ford 6.2 is it seems like it will create less storage and bigger engine compartments?

GM still definitely makes the 5.7 Iron Block and heads in Toluca, Mexico.

Nothing has been announced to that effect... its just speculation by the OP. I doubt very highly that Ford is getting back into the marine industry.

5.0 would make a nice 350+hp package out of a small displacement engine but its wide like the 6.2. May not fit well in narrower or DD boats.

Im still waiting for MC to throw some of Ilmores V10's in the bigger boats

With all the cool water available to intercool a turbo'd engine, this would be the ticket to a higher efficiency boat.

Like you said, the problem is that you can't cool the exhaust until after the turbo, so the now dry exhaust manifolds and the turbine would be HOT.

Boat with a cooling fan, anyone?

I'm guessing either a CVT of some sort.
or


Diesel :)

Look at the Mercruiser twin turbo 9.0L v8's. That is how you cool the turbos.

they would use water cooled turbos to solve any heat issues

A regular water cooled turbo only has a water jacket on the bearing section. The turbine still gets red hot and the compressor hot enough to turn high temp paint.

Those Mercury engines look like they have much more significant water jackets on the turbos. Very cool. I wonder how much they cool the exhaust gasses. Obviously they have it figured out.

When it was time for a major increase in max power and mechanical efficiency with our engines at work, we dropped the water cooled exhaust manifolds for dry manifolds. Keeps more energy in the exhaust for the turbo.
