I am trying to figure out what is the problem with my boat it is a 1986 Forester 180 Phantom with a 1985 or 1986 Force 125 with just myself in the boat and a 1/4 tank of fuel I can only get 32 mph out of the boat on the gps and a wot of 4100rpms
The prop has no size stamped on it but on the hub it says "michigan 072107" so I checked to see if that was a michigan wheel number and it was a 17pitch prop for a force outboard. I just dont understand how the boat could be so slow. According to a forester brochure it says the boat weighs 1090 pounds without motor so I figure about 1500 pounds with motor and fuel to be on the safe side. My dad had a 1985 bayliner 19 Capri with the same motor and it did close to 50 mph.
My guess is the boat is totally proped wrong but i've read so many different things I dont know what to believe. I would also like to add that the boat has 150lbs of compression in all 4 cylinders, new plugs, and runs on all 4 cylinders.
Can somebody please help me
