I have a Honda 15hp 4 stroke mounted on my 1985, 16’ Alumaweld flat bottom sled, and have a issue of what feels like the prop slipping, when the boat is under load and at speed. The motor starts fine, runs fine, with no other issues. I marked the prop and ran the boat to see if the prop is spun, but it is not slipping. Curious if the motor is missing, so changed the plugs and no difference. The old plugs were Tan color and looked good. Has anyone had this problem. Cavitation? Carburetor need rebuilt?
