Has anyone looked into using a Corvette C-7 LT1 engine
for marine use? The engine has amazing HP and torque.
There are those that say you need big cubic inches, but
the LT1 fells like a big block.

Years ago I put a 350HP 327 in a 18ft SeaRay. The boat ran
great, but it did take awhile to correct reversion problems.

I always wondered about that too. HP is HP and torque is torque and with the weight savings over an iron big block, seems like it would work well. Not made for marine use so closed cool or flush religiously.

Ayuh,.... A few of the Problems I can think of are,....
An Intake manifold, the Exhaust manifolds,...
'n Aluminum doesn't live very long in saltwater,....

THerre are several threads about using ls motors in boats.

Can you point me to them. It would be the same problem.

Thanks,

Warren

There are several current and several not too old build threads if you look around

Your quick - LOL !

The LS thing has always been on the back of my mind. I have a friend who owns a large autoyard, and is into boating (used to have a top gun). So I could get a donor motor cheap. Its all the electronics/computers.fuel injection stuff that scares me. Hell I rewired my entire boat from scratch, but looking at all those plugs, sensors, pickups, black boxes etc just baffles the hell out of me. Change a cam. no problem, change exhaust, fill and make new holes in the transom for the new exhaust, no problem, Try and figure out out 8 different ign coils and the right crank trigger hooked up to god only knows what else..definit problem.

If they can put the supercharged Cadillac cts -v in outboards and centurian wake boats couldn't imagine why not .if you have the money .
