re: 7 Marine engines

Aren't they something like $80k a pop? The closed loop cooling system is kinda of neat but outside of that I struggle to see the value in them. Not sure I would go the seven marine route if I were building a tournament center console when I get the yamahas for half the price.

Yeah, the 557s are like $80k. No idea on the 627. The way they got that whole engine working is awesome. I read that they have to have custom designed props for their engines, and off the shelf stuff won't work
One thing is for sure, they are no joke

Problem is that once you get to these 40 foot plus center consoles they are weighing in close to 20k lbs or more and take monster horsepower to move. You would need quad 300s which is more complicated and more prone to problems and uses more fuel than a twin 557/627 engine setup. Not to mention the 557 weighs less than two 250-300's. Plus twin skegs in the water is less drag than 4 so top speeds of the high horsepower twin will be greater than the quad. That said builders are going even larger and strapping quad 7's
