Ok, so I just picked up a 1999 Nitro Fish and Ski boat with 150hp mercury nitro serious 2 stroke outboard motor. I test ran it yesterday and noticed that the boat tends to want to go to the right so I have to put a firm grip on the steering wheel and put a bit of force on it to keep it from going to the right. What's causing the motor to pull to the right like that? I checked the stabilizer thing (grey object looking like a shark fin, just right above the prop) and it's not broken or anything. Does anyone else experience this on their motor? Is this an easy fix? I am pretty handy with the tools and have done work on my previous 150hp xr6 motor myself. Please help because I have no clue where to begin checking on this problem.
