Find out where you water line is Walt. And then see how high your turbo is above the waterline. Because that is the path it will have to take. It is likely closer than you think. I think you want a minimum of 12 inches. My boat is one of those that Cummins signed off on the installation and it is allegedly less than 12 inches although I haven't measured. It seems more than that but Timjet says his is only 9ish inches above the waterline and I think he has had damage to his turbo due to water intrusion. Just remember how low your engine is in your boat. Now if you have a "loop" or a point where your exhaust goes higher than your turbo then that helps.

It is ultimately simple physics. If the water CAN flow....it will.
