Re: 225 or 250 HP too much???
Had an 85 rated for 200 hp max, got an 86 rated for 235 hp. I don't think these boats were ever rated for more than (outboard) 235 hp. If you put on a 250 your insurance company may have some questions (BIA hp ratings for the boat), especially if you have a claim.
I/O hp is different with a max. hp of 260, typically a 350 chevrolet. Remember in 79 outboard motors were rated by powerhead hp and not prop hp like the newer motors. An old powerhead rated 200 may only generate 170 hp at the prop. Just my $.02
