Still looking at it. If I paid myself a nickel an hour for the research time I coulda bought a new one already. I think Kelly Controls is gonna be the answer to my dilemma.

Waiting on a response from Steven Li on a few issues like the momentary on and any additional resistors/flux capacitors that I may need. Looks good so far. I think the throttle is gonna be a slam dunk factory type retro-fit. Nice because I am not sure how salt-proof they are. At $19 I don't see it being a big problem. The control unit may need to be mounted in the semi-dry hatch directly under the motor. Might need to get rid of the foot switch too. I'll conjure something up and let everybody know what I got.
