Help me out here guys. I have a 1972 Stardust cruiser with a 1972
Mercruiser engine. We took it out the other day and while we were
driving, the boat went into idle and would not go back into
forward. The control goes forward, but it just won't shift. It will
go into reverse, but obvoiusly I can't drive it like that! I am
thinking it's a shifter cable, but how would I tell if I need to
adjust it or replace it? Or if it isn't the cable, what else could
it be?
Also, I have a 6.5kw mcck Onan generator that runs for about three
minutes and then shuts off, even with no load on it. I have
replaced the impellor and changed the oil. I have even tried
disconnecting the heat overload switch to see if it was faulty, but
it still shuts off. And it's not a sputtering stop, like running
out of gas, it's an automatic shut off, like an electrical problem.
Any ideas of what it could be?
Dont claim to be an expert on this but here goes. starboard side of
the carb there are 2 cables. One goes to your shifters MMC or what
ever. The other runs down to your out drive. on the transom. Unhook
the one down to the transom and try to move it to manuely shift it.
Dont run the engine but you can get somebody in the water and
have them turn the prop to see if it goes into forward and revers
and neutral. If your cable pulls out of the housing at the
end you unhooked the cable is broken. If this seems good work your
controls and see if everything works at the engine. It should
be smooth and move an amount that will shift the drive. Good
luck.
Your generator still seems like an overheat prob. Do you have good
water out of the exhaust were all of the old impellar pieces
accounted for. A lot of the time there are rubber parts left that
will plug a heat exchanger or passage. I dont know
yours but most gen sets have an overheat switch on the exhaust and
on the engine block. Good luck. Post what you
find. Gen problems are the number on prob on all of the house
boats i know of and on all three that I have had. A
koler, Onan, and now a westerbeak. Just replace and overspeed
circuit board that would quit after running about 30 min.
carbis I was thinking about your problem and may have
steared you down a bad road. The first thing to do is watcch
the shift mechanism at the carb and have somebody work the
shifters to see if it is moving anything. If it is working then
unhook the cable to the out drive and try it manually.
