See that several people have changed out the throttle cam on their Tohatsu 9.9 to take it to 15 hp. Everybody reports this as an easy changeout, but we have the boat in the water, and since the screws that hold the cam go in from under the coil plate and flywheel, it seems really tricky to get the old cam out and the new one in (too little clearance). I've looked all through the manual, but it looks like my only two choices are to take the engine off the boat, so I can lay it down and change it easily, or I have to pull the recoil starter, flywheel and coil plate assy. so that I can flip the plate over and change out the cam. I am new at outboard boat maintenance, so maybe I'm missing something about how to do this easily. Any help?
