    Force 70hp New trim motor

    I replaced the trim motor on my 91 Force 70hp. The problem is that I’m not able to go fully up or down. At the time of replacing it I had the motor trimmed down and filled with fluid and worked it to about 1/4 of the way up then added more fluid. When getting the motor trimmed all the way up I...

    Force 70 HP - Full throttle in reverse but underpowered in forward

    I thought so as well but didn’t go too deep to check the gasket but we put it on muffs today and the top plug looked like the others today.

    Force 70 HP - Full throttle in reverse but underpowered in forward

    I replaced all 3 about 3 days ago. I’m thinking it maybe be something with the carburetor, maybe dumping too much fuel. But still not understand why I’m not getting to WOT in forward. I’m kinda at a loss with this thing.

    Force 70 HP - Full throttle in reverse but underpowered in forward

    Okay so I removed the reed valves out and they look fine. I’ll post a picture of them on both sides. While take the bottom reed assembly off there was a puddle of fuel in the bottom of what I would assume is the intake on the bottom cylinder. Crank case compression is good as well.

    Yes we’ve tried up to 1/2” gap on all. We got spark all the way through. Yes, it is a single carb motor.

    Force 70 HP - Full throttle in reverse but underpowered in forward

    Ive checked spark and compression, but don't remember the numbers. i will do another test though! The spark plug isn't a traditional style, it use a NGK BUHW.

    Force 70 HP - Full throttle in reverse but underpowered in forward

    I have a 70 hp Force outboard that is having trouble getting WOT in forward gear. From what my tach says, its getting to about 3000rpm in forward gear. When shifting to reverse i can get full throttle of about 5000rpm. I've done adjustments from both engine side and remote side with no luck. Any...
