I recently purchased a 99 tracker 185. took it out for the first time today. I am new to the boating world, I have owned a few small boats in the past all being tiller controlled. while driving, the boat leans (or lists?) to the left rear. also it feels as though I have to fight it to keep it straight. I i let the wheel go, it pulls to the right. Again I am new to this and not sure how to tell if the trim is correct. if I adjust trim as we are going along I can get the bow to drop or raise a little, but I can not tell if I am "on plane" or not. and it does not seem to affect the listing. the motor is a merc 90, and there is one of those fins on the lower unit. the hull appears to be in perfect condition with no dens or obvious damage. any help here would be greatly appreciated.
