Over heating

Oct 30, 2019

Lately, it seems, my Beta engine has been approaching overheat. It
never used to.

I've cleaned the stack twice, topped off the coolant. (Is there a way
to flush out/drain the whole freshwater side?)

Hi Victor

Ensure you are getting a decent water flow. Flush complete system (Fresh and salt-water). Clean heat exchange tubes carefully, change O rings. Check thermostat (Take it out and see if any different).

How do you know it is overheating, alarm or gauge?

Cheers

Greetings Steve,

The alarm did go off at one point and I've kept my eye on the temp
gauge ever since. The Beta manual is on the boat so I can't check it
now, but, does the manual explain how to flush said systems?

Have cleaned the tubes twice now; but sometimes have trouble with the
reinstall. It's difficult to get everything line up. Is this typical
or is it possible i'm not reinstalling correctly.

Thanks for the help.

Cheers

Victor, when the alarm went off was the tempreture actually high or was it just the alarm?

I had an incident on a vega with a new Beta, we were struggling to get into Newlyn In Cornwall against a full 7 to 8 wind, it was night and the seas were horrendous, the alarm went off and at first I switched the engine off but in the end decided I had to use the engine alarm or no alarm, with motor going and sails up tacking into the near gale it took 7 hours to cover 14 miles, the engine coped and the alarm didn't go off again. Two days later we sailed from Cornwall to Southern Ireland and had to motor most of the way. As you can imagine I watched the engine temperture very carefully but we had no difficulty in nearly 24 hours motoring. I can't explain what happened but if it happened again I would open up the engine compartment and check just how hot the engine felt before deciding whether to continue with engine or not.

Good sailing

Hi Victor

Bit fiddly to change but ensure you change the O rings at teh same time. Manual explains, I think!

Just a thought, Mikel: If you were beating into the wind with the
motor running, maybe the raw water intake was coming out of the water
on one tack?

That is a very clever suggestion!

I will add that to my list of things that I should remember...

My engine (MD6a) manual prescribes a max degree of heel with engine
running - presumably for other reasons?John

Peter _ Hadn't thought of that one, we were certainly heeling although heavily reefed. The water intake was at the usual point in the engine compartment only 15 cm or so off the centre line so it is not likely that the water flow would have been interrupted for long despite the very lively sea state. I think the alarm is rigged to go off at a certain temperature rather than lack of water flow and with indirect cooling on the Beta it should run for a while without the raw water flowing.

Sometimes an engine will overheat from heeling, I understand as a result of oil distribution being affected, esp. if the engine oil is a bit low.

Also you might have been getting air in the raw water intake from time to time.Nicholas H. Walsh P.A.

The temperature gauge was also high. Tried cleaning the stack again
today, fresh coolant. We'll see what happens.

When I heel over too far on the starboard tack I can hear my Yanmar
right away .... it starts popping loudly. My usual exhaust is very
quiet (Vetus wet exhaust).
