I have a 1989 85hp force motor, when under load and I try to put it in reverse it keeps stalling.Going forward is fine, only in reverse and under load.I 've had the boat about 2 years and it slowly started to happen more often.Now it's becoming increasing difficult.I have never done anything to the motor besides gas/oil since I got the boat. How should I start to clean maintain and solve my problem? Any ideas? Thanks
