The one OS makes for the OSXM outboard is the shiznits IMHO, Gabe Clegg (StumpFab/NovaRossi Marine USA) carries them. Or make one with 1/4 x 0.032 brass plate and brass tube, using short piece of fuel line clamped over throttle cable to lock in place. Bolting to crankcase motor mount lug is better than using crankcase bolt.
