If you prop correctly, a 90-100 hp four stroke is just fine and about 370 lb for a yamaha. If you over prop it, it is a dog. Yamaha made Mercury power heads for the 4 stroke 90hp models until the change to EFI or maybe later. I have a 2000 model year. If you treat the carbs right, it is fine. I got mine for $1200 with a boat. But double that is more realistic.
