I have a 277cc 2 cycle Rotax engine with point ignition and a built in
charging sytem on the flywheel. We are using this engine on a homebuilt
air cushion vehicle (hovercraft) primarily on salt water. The salt
spray is everywhere. The points become encrusted within a short time
and the engine will not take high rpm's or simply quit. Fresh water
spray around the points produces the same results. Is there a
replacement module that will eliminate the points altogether or as a
last resort a circuit that uses the points as a low current trigger for
a transistor or the like to initiate ignition? I am assuming if the
points are used in a low current configuration the degraded current
carrying capacity would not be as big an issue. Covering the points and
venting them would be my last choice as it makes it very difficult (
impossible) to adjust through an already small inspection hole. Any
ideas will be most welcomed.
Cheers...Gerry
PS. I have thought of replacement Solid State ignition modules for
lawnmowers etc. but apparently the built in charging coil on the
flywheel will not allow this setup.
