Just to make sure everyone knows that dyno test of the 525 was full marine, wet heads and all. And that motor will run on 87, I think you will have to run 91 with the compression you are running. Again, we will see when you get it in the boat. That will be interesting.

Thats cute. Those are going to be STOCK everything with a cam, carb, intake. He could give two ****s if he does 70. Im really starting to enjoy the ball busting. Really makes me appreciate posting this build. Maybe Ill do some 1000hp prius motors next or get a chevy volt that was crashed and stuff that in a trash barge and take a poker run by storm.

I feel like I'm missing something with this handful of people vs MGG Doors. What am I missing ? Another thread ? sometimers ? Or did I not read a bunch of this thread?

You have high compression (yes 11:1 is high in the marine world), cammed stroker motors. You still don’t beat a stock bottom end 525efi anywhere on the dyno sheet. You rev a little higher. Your words were you were gonna make it look like a fool through the whole powerband. My engines are stock bottom end. Iron headed with no work done. Carb motors with a cam. 8.7:1 compression and I beat you through the powerband to 6k. I’m 20k in on both motors.
Youre right in saying theres only a few LS powered stern drive boats. I wonder if it’s because it doesn’t work. Let’s think logically here. If it was that easy and so much cheaper don’t you think it would have taken off like wildfire? Threw some nice supercharged 550hp LS stuff in wakeboard boats that would likely be a beyond suitable replacement for say the 525.
Again the results are always in the boat. The paper numbers always work and yet real world hasn’t
