My advice is to go with a 4 stroke.They are much quieter than the two's and you don't need to buy any 2 stroke oil.With the technology in the motors today you can't really go wrong with any make.I had a 90 Optimax on my Lund.It ran awesome,had lots of power and was great on gas and oil.However at cruising speed(24 mph@4200 rpm)it was loud.We regretted not going for the quieter 4 stroke.When I was fishing it wasn't an issue but when the wife and I went for a cruise we had to kind of yell over the engine noise.I'm just throwing out a consideration.
