Freeze Damage to Sea Strainer and Kohler generator

DavidWMackenzie

Attached are pics of one of my sea strainers that was leaking.  It was not leaking last fall when I laid the boat up for the winter but is now.  I suspect that my marina did not winterize properly.  Does anyone have another theory?

Fyi, this feeds my Kohler 5E 5KW generator which now has all its oil sitting in the pan underneath the generator.  I fear that I may have a cracked block due to lack of winterization.  Thoughts?

Those strainer types do not hold up well over time.  I think the bowl would have cracked if froze. The raw water only goes thru the heat exchanger, the engine has antifreeze running through it. So unless you had only water in the coolant system, not a cracked crankcase from freezing. 

Oil in the drip pan might just be a sloppy oil change or the drain valve not fully shut.

I agree with BD.  I'm betting the oil in the pan is just a sloppy job for oil change &/or them leaving that valve a little open.  First check the dipstick.

The strainer looks like it could have been over tightin but does look to be aged. X2 on oil change that is a little hole to get oil in and you have to pour vert slow.

Strainer for my A/C cracked just like that last year. I never ran it so I did not winterize it, but water got in there anyways.
