Dumb ass move

[Lew]

Short story, just serviced port Heat exchanger and installed smx 160 thermostat. Was excited to try it all out before I serviced  the SB side. Went out of the harbor and watched sb side climb from like 180-210 when I put load on about 2200rpm.  I noticed white  smoke that I don’t usually have. “CRAP” immediately shut down and ran down stairs. Opened sea cock. Re started engine and temp fell quick and smoke gone… 

Got back in checked impeller also new SMX pumps last season, and no damage. Coolant level did not drop.

What are there chances I destroyed this 330 6BTA, that has run flawlessly with 2200 ish hours.

Thx

Copy that Rob, 

the manifold looks fine, no coolant loss. What else would I look for?

I am in process of servicing heat exchanger on this engine now and will also install a 160 smx thermostat.

Thx for reply

Chances?

I’m in the 0% chance of you destroyed it because you caught it in time.

Figure some alarms would have sounded if you got close to causing damage.

Any symptoms of damage?

Did you cook the exhaust manifold enough to turn the paint brown?

FYI – if an engine is still circulating coolant (didn’t throw the belt, etc) letting it idle and move coolant can be a good thing to avoid damage from hot spots.

A good fail safe is any time you close the seacock hang the ignition key on the seacock.
