Well hello there.
Just got on my uncle's Leopard
42 with 2x Yanmar
4JH45s. Seems we have a little trouble starting the portside diesel engine
. The engine
cranks no problem, but doesn't seem to catch. We can get the engine to start by manually priming it (the auto primer no longer functions), but the engine dies as soon as its in idle.
When we manually prime the engine and get it to start, I'll throw it in neutral and give some throttle to make sure the engine runs, which it does. As soon as I release the throttle, the engine dies. We've replaced all the filters today, but it still doesn't work
Couple ideas being tossed around here.
We've heard maybe it's got to do with the diaphragm
We're thinking there's air in the system.
Does anyone have any ideas? Please
EDIT: Tried correcting the title of the post, but don't know how to.
Also, it's a brand new boat
. ~110 miles on it.
We heard it's possible that when assembling the boat
, there may have been some debris that accumulated in the diesel
reservoir. After some rough(ish) seas, it's possible this stirred up the debris, which flowed through the lines and caused a partial blockage. This would be enough to cause the problem.
