Our Kohler 8EOZ won't start. Yanmar 3TNE74 engine. Not finding solutions in the Kohler and Yanmar service manuals.
Last time we ran it was approx early Oct, maybe Columbus Day or thereabouts... then we didn't happen to try to start it again until approx 9 Nov, i.e., four days after we left home on this current ICW trip. When we tried, that time, it failed to start.
I think I closed the seacock almost immediately...
The symptom now is that it seems the starter is engaging, but the crankshaft only moves about an inch, then maybe returns to original location, can't quite tell...
And I can bar the engine over manually.
Once we eventually landed in Jacksonville last week, we did a load test on the 10-year-old battery. Sure enough it was likely an issue, possibly the original cause, even though voltage tested at around 12.7V (dropping to 10.3-ish during a start attempt). Got a new battery delivered today, no start, same symptom. Haven't (yet?) done a load test on the "new" battery, but one generally expects a new battery isn't likely the cause.
I know what hydrolock (hydrostatic lock) is, but I think I closed the seacock almost immediately... And I can bar the engine over manually.
Could it be hydrolock anyway? I've got feelers out to find a good Kohler generator tech in Jacksonville... but if it's hydrolock, is there something I can be doing myself in the meantime?
Naturally the starter and battery/ground connections are on the backside, and physical access there is likely gonna need some carpentry through a stateroom...
