Intermittent starting problems with universal
Have a Universal m3-20 18hp installed in our Newport 28. First boat for us and first exposure to a diesel engine. Been having intermittent starting problems.
About half the time the time the engine starts right up after holding glow plugs for around 45 secs- 1 min and cracking the cracking the throttle open about 1/3 open.
Other times, using same procedure the engine cranks and cranks and nothing. We ususally wait with the glow plugs on a bit longer and t hen try again. nothing. We repeat this process several times over next 5 mins or so without any luck.
We usually give up and let it set for a while (5-10- minutes and t hen start over with same procedure and t hen it usually starts fine.
Seems odd. Air tempture seems to be same as does everythging else but sometimes it starts right up and sometimes it just doesn't even act like its every going to start.
Engine has low hours (under 300) and battery seems strong, seems to crank strongly and fast. We are new to diesels so we are wondering if it is somethng we are doing wrong.. It also runs and idles fine after started.
