Shift clunk at idle

[Boat_Boy!]

I have a Yammy C40 that give a big clunk when I shifft into forward or reverse from idle. I don't think I can lower the idle speed because it often stalls when I shift into gear.<br /><br />I would really like to be able to get this thing to troll down a bit and be able to start it more effectively. Any ideas?<br /><br />New carb kit, timing is correct, idle seems to be at correct RPM, new plugs.<br /><br />Thanks guys and gurls.

Re: Shift clunk at idle

Boat_Boy<br />Realize that the shifting of gears on all outboards involves ramming a non rotating clutch dog into a rotating gear. The faster this happens<br />the LESS wear on both parts. Notice I said faster shifting, not faster idle rpm. When this happens it produces a "clunk" which is fine and normal. A thunk, thunk, thunk, thunk, clunk is what you do not what. Pause in neutral when going from forward to reverse or r to f. Idle rpm should be at factory specs, probably 600-800. Any lower rpm will depend on engine tune and your ability to deal with shift/throttle situations.<br />Backfire
