Good to know. My CMI's are the 1 piece header/tail combo so there isn't much wiggle room at the transom. Thanks for the info.

OK I read it as the exhaust is .300 higher, just over 1/4". I didn't realize you added it the deck height as well.

I'm not too worried about the fuel, this is just the fun boat. The drive is a big shaft SSM #4 so strength is enough for 800HP. I'm just afraid the CAM is a bit too sporty for marine use. I'm going...
