Tohatsu 50 throttle

Getting the boat ready for summer with some cleaning and general maintenance only to find my throttle cable has snapped.

Does anyone have an idea of the best place to get a new one? It's a tohatsu m50d2.

Also bit more worrying the throttle is very stiff. The rods and linkages all move freely but the silver part of the throttle assembly below the flywheel is very stiff (in photo) I've taken off the pull start assembly & have undone the nut on top of the fly wheel. However the flywheel won't come off. I've tried tapping it free and levering it free but it won't budge!

I think all it needs is greasing but I can't get the thing off! Anyone have any ideas?

If you're removing the flywheel, don't hammer it. Use a little Plus Gas or Duck Oil Penetrating Release on the exposed bolt thread and use a flywheel puller.

Once you get the flywheel off take the lighting coils off, you get a few more RPM for free, removes electromagnetic drag from the engine.

I used a flywheel puller, tighten it up and give it a gentle tap with a rubber mallet, came straight off.

And it's off!!! Took to a local garage in swanage. Put a flywheel puller on & even that struggled to get it off! All that needed doing was greasing the throttle & it's all back together. Click image for larger version

Throttle cable should arrive tommorow & fresh spark plugs on there way! All I need to do now is give her a clean & I'm ready for the season
