Westerbeke 7.0 BCGB Genset
My westerbeke 7.0BCGB ran great the day of launch as we had no shore power I let it run for an hour or so to charge up the batteries. We changed the cap and rotor over the winter and it was actually running smoother than ever. Came back a couple of days later and since then it runs for 18-20 minutes and then shuts down. I can restart it by holding the "preheat" button but as soon as I release it it shuts down. Wait half hour and I can start it but the cycle repeats itself. First thought is overheating but we just replaced the water pump and it's pumping fine and the discharge water is cool to lukewarm at best. Looking for direction before calling the mechanic. Thanks in advance.
