In this video, I have a Westerbeke 8.5 KW marine generator that surges at idle and also underload. I take it through the full process of how to adjust the governor and also adjust the engine speed to obtain the correct 1800 RPM to achieve 60 Hz frequency.. so come along the step-by-step procedure and if you got the same problem that I did, I’ll help you fix yours just like I fix mine. you should check out the Jeep King channel for many more boat projects in Marine application, maintenance and repairs. God bless.
