[FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica]Well I'm sure this is along shot but I have nothing to loose.
1978 Cruisers Villa Vee with twin mercruiser 228's and BW velvet drives.
The last 2 times I've taken the boat out the starboard motor has quit. This is after running at around 2000rpm's for just over 1/2 hour. Will not restart.
First time back at the dock we do trouble shooting. Using a timing light looks like no spark. Switch coil, replace rotor and cap. Still nothing, then notice a wire on the + side of the coil is frayed. Repair this and the boat started right up. Problem solve, or was it?
Yesterday at about the exact same time frame the starboard motor once again stops running. Again back to the dock. Pull the fuel water separator and a little water but not much (both motors run off the same tank) we replace F/W filter, carb filter and inline filter.
Motor starts up and we let it run. After 35min or so quits again, is something getting hot?
I converted both motors to electronic ignition years back. So switch the electronic pickup from one motor to the other.
Start both motors and run at 2000rpms for 60min no problem. Shut down and decide to take the boat out to be sure. Run the boat up on plane for around 20min or so (3300rpms) and back to the dock, not problems.
Today figure I'll run it again to see what might happen, runs fine for another 60min and I shut the motors down. Decide to restart just to be sure. Starboard would not fire, turned over but no fire. Wait about 10min and now it fires up and runs.
Temp gauges on both motors shows around 140 but could something else be getting hot and causing the problem, electrical or fuel?
Sorry this is so long
