Re: Westerbeke preheat with torch?

I have read that engines with pre-combustion chambers can be severely damaged by ether. I used a very small shot of it once in my VW diesel in -15 degree Fahrenheit weather after just about...

Re: How do I keep bow from falling off the wind anchoring?

Ah, could be, as mentioned, I have never tried it. If the tiller is free it may not sail too much, unless the boat is perfectly balanced on the main alone? Our boat always had a bit of weather helm...

Re: How do I keep bow from falling off the wind anchoring?

Have not tried this, but if you have the jib down & the main still up, sheeting the main in tight, with the traveler centered, may reduce the bow fall off?, easy to try ahead of time.

Re: What would cause this?

Maybe some blue Loc Tite on the shaft threads at the next prop install? Not quite sure how the other "Locking" washer or whatever it is works?

Re: Thawing frozen engine

I think it will trip if it senses any ground, such as a short to the heater chassis or other ground source. Good point about pure load however. Hopefully, the shore power source would be load...

Re: Engine running cool

The last shower head I bought had a small removable restrictor "sleeve" in it. Somehow, it removed itself & now I can dig holes in my back if I want to. We have over 75 lbs of water pressure.

Re: Thawing frozen engine

Interesting thought. Not sure if the new ones have a mechanical thermostat?
In any event the OP's insurance company, if he is insured, may have some input on the subject.

Re: Thawing frozen engine

Assuming you have properly grounded shore power there are all kinds of small space heaters, without fans or flames, similar to base board heaters, or upright oil or coolant filled heaters. Not sure...

Re: Synthetic Motor Oil for my Diesel?

I am guessing here a bit, but the theory may be that as the water warms, it rises or expands, creating a "flow" of sorts. It also may matter where the heating element is located in the block. Every...

Re: Yanmar low oil pressure

I have read about some filters causing that problem, maybe try a Yanmar filter?

Possibly, the electric sensor is heat sensitive, Maybe try a new sensor, or temporarily hook up a mechanical gauge....

Re: Radiator Cap

Ah, I had the flow backwards. "Two step clamps", that is what I thought, but really couldn't see it too well from the pictures. If the tubes are sound it appears the boot is the only place for the...

Re: Radiator Cap

Interesting. Went back to look at the pictures, I assume the coolant passes through the tubes from one end to the other & sea water circulates around the tubes inside the "canister"? I can't tell...

Re: A 100 year old gaffer

My Dad & his partner had the "Flirt" (Page 8 of the link) on San Francisco Bay in 1945. I remember many a rough windy day on it. IIRC, my Dad said it was originally Gaff rigged, later converted to a...

Re: Yanmar 3GMD unburnt fuel/ black smoke/ Exhaust

Went back & read your original post. It appears the smoke started right after you cleaned the cooling system. Curious to know how you cleaned it? If it smokes right at the open exhaust manifold it...

Re: Yanmar 3GMD unburnt fuel/ black smoke/ Exhaust

Maybe a gasket(s) re-installed backwards?. Maybe the timing was disturbed? Any changes made to the injector pump? "New" injectors?, maybe the wrong ones?, or a bad "batch"?

Re: New Honda 2.3 outboard not running

Curious to know why the racing fuel is recommended for air cooled engines only? The only thing I can think of is that air cooled engines may run hotter,
helping to vaporize the fuel better, or...

Re: Synthetic Motor Oil for my Diesel?

before the recommended interval, 6,000 miles, IIRC...

Re: Won't Start after 4 hours of cruising.

Some possibilities:

1. Tank not venting properly

2. Air leak in the fuel system. Your electric pump should pressurize the system, assuming it is upstream of the filters, & may show where the...

Re: Radiator Cap

Re: Radiator Cap

I think the raw water circuit is under whatever pressure the pump puts out, not a whole lot, & that the raw water circuit would run considerably cooler than the coolant, after everything warms up?
