two things get repeated often on this site:
if you want to make a small fortune restoring boats, start with a large one...
restore the boat for you, not for resale...
the switch in the handle is operating the contactors which operate the motor.
no way to run motor wiring thru a switch small enough to make it fit into the binnacle handle
a 20-30 amp switch is going to be fairly hefty
I would use a pair of $2 VF4 relays
my issue isnt having to replace the idler, its having it go bad with only 24000 miles (under 39,000 kilometers). so if that bit of plastic bit held on to a cheesy spring is failing, what other plastic bits will soon be failing? the dang oil pan is plastic.
