Running Twine Force 125

[Dave52]

Both engines are running at right hand props so you can imagine its a bear at WOT to make a left hand turn. So what are my options to change one of the props to a left hand rotation. I have looked at replacing a lower unit but looking at parts listings they dont specify left or right hand.

Na, an, na, na---It don't work like that. It 'aint never that simple

Force never made a counter rotating engine. There are no left hand gears and no left hand props. Basically yo must live with what you have.

Even if you could find parts, you would need to run the engine in the opposite direction, counter-clockwise,you would need opposite rotation gears so they would be loaded on the proper faces, and a counter-rotating prop.

By the time you get all this set up, you are better off buying a set of big name engines.

Never crossed my mind that the direction of engine rotation governed which way the prop turned. Rather thought that the lower unit gearing was responsible. But if your correct and as you say, its something I'll just have to live with.

Some outdrives on I/O's have gearing to make it counter rotation.Not outboards.
I have a set of twin 85's Force.I had the same problem you did. I started by moving the exhaust snouts..Turn both the same way it might help.
What really helped was the steering was too weak and finnaly broke.Then I replaced it with hydrolic steering and it's like I have power steering.Jerry
