LOL!Ok, I think I must be sheltered.
What is a Key Hopper? Is it a Flats boat?
Any updates on what's going on with the Key Hoppers?its actually a 250, i had just purchased a used cowling and hadn't re-stickered it yet... with a saltwater series 23 blade prop I got 73 or 73 out of it. The best part is it cruises at 50-55 w/o any effort, putting a big motor on it, made it like having a new boat....As far as fuel consumption, I never check...its a toy!!!! who cares, its not like I drive it to work everyday! (or atleast thats how I feel about it)....
post some pics of your 90, I would love to see it.
