Opinion on 28 Heat power
I'm entertaining the idea of going to a new 28 Heat, but not sure on which motor to go with. Looking to go 80-85mph. Would the 540 do it, or do I need to go 565, or bigger?

My 2000 (stepped) has a 500EFI (475hp) in her, runs pretty solid into the 70s, damn near always. That being said, I would think at least 600 to get you there. Are you going with a MCOB or closed bow?

It will take 600 hp to get you to 80 possibly 81-82 with the right prop and depending on your elevation. Most of the wood free Heats that I know of with 600sci engines run right there including mine before I did the Whipple upgrade.

MCOB. I did some more reading on the 520 and I really like the 2 year warranty and the ITS feature. I may forego some extra MPHs for reliability. Anyone have any experience with the 520? I wonder how receptive it is of a Whipple later down the line. From what I understand, it has forged internals...

How do you like the ride in the Heat? I currently have a walk-through Rage with a 502 HO and love it.
