I have a 1986 Johnson 15hp long shaft outboard on my Mac 25. It works great. But the throttle arm when in the horizontal position hits the transom of the boat and prevents steering so I have to have the arm angled at about a 60 degree angle to be able to swing left and right. Problem is this throttle arm has a gear that connects to the motor and main throttle and at this angle the gear skips and will not hold RPM's. Thought about trying a motor mount that would hold the motor out futher from the transom but am afraid of the leverage and weight on the hull? I have already beefed this area up to handle the 15hp. Is there a remote throttle I could use for this motor?
