Hi Derek,
My 2QM20 might be a similar vintage to your
engine. Mine has a fuse near the back of the
head, port side, that has a connection which
often comes loose. The symptoms shown have been
no idiot light at panel or lights okay but no
starter power. So far I've cured by wiggle action
but one of these days I know that isn't going to
work anymore. It really needs new connections, no
"spring" left to grip the spade.
Cheers, Russ

Iâm having ignition problems with the 2QM15
engine in my C&C 30 mk1. Normally, when the main
switch is turned to on, the oil pressure alarm
sounds. Pressing the starter button starts the engine and the alarm stops.
This season, after a few successful starts, when
I turned the main switch on one day there was no
alarm and nothing happened when I pressed the
starter. No cranking. Not a sound. My batteries
spent the winter in my basement and were fully
charged. As well, shore power was plugged in and
the charger showed full charge on both batteries.
This happened once or twice last season but when
I repeated the process the engine started.
I assumed that the main switch was worn out and
ordered a replacement Yanmar switch from
Rosborough Boats. It was my first dealing with
them and I was very impressed. Rob Manual had a new switch to me within a day.
I had carefully labelled and photographed the
connections at the old switch before removing
it, but when I installed the new one it didnât
solve my problem. When I keyed the switch on, I
got a very weak sounding alarm and pressing the starter button got no reaction.
Iâm unskilled at tracing problems, so thought
Iâd ask for help. Thanks in advance
