A while back I posted a few of the issues I discovered on my trawler in the return cruise. I'm still having issues with over heating in my stbd engine. (Perkins 6 cyl 135).
I changed the impeller out and I replaced the coolant. Engine then went into repair for a fuel injector leak.
Now fuel pump replaced and today went for a short cruise. Engine was 3 gallons low on CoolAnt! Put new Coolant in and started engine. Noticed coolant was going straight out the engine exhaust. Water was green. So I went out under idle to run her a bit because I wasn't sure how much I lost but didn't seen like too much and engine temp was steady.
Noticed temps starting to climb so came back into marina. Engine went to shutdown when trying to dock and I ended up taking another slip due to wind conditions.
Now I am trouble shooting it.
Thoughts?!?
Engine oil is black. Don't think it's a head issue and I didn't run it past high temp alarm
