Typical boat stuff, last October when I winterized my genni was running fine. Yesterday I commissioned it while still on the hard and it is giving me problems. It initially started and then ran for about 90 seconds and then shut down. I restarted it a number of times and each time it would run for a few seconds and then shut down. I have reviewed the Westerbeke owners and technical manuals and I know the shut down system has 4 components: oil pressure (normally open) water temp (normally closed) exhaust temp (normally closed) and engine overspeed. I know I can jump out each of these sensors to see which one may be causing the problem but based on the fact that it started and ran I am thinking that the over speed switch may be the problem. I plan on jumping out each switch and if the over speed is the culprit to then measure the RPM with the switch jumped out to see if it is within the 1800 RPM spec. If it is then I guess I will suck it up and spend the $195 for the over speed switch. Anyone been here and done this? Got any other thoughts for me?
