can any Human hand start a Yanmar 2QM or 2GM?

MedSailor-

Good post... but I think you need to add emphasis to this paragraph:

BTW don't mix the wd40 trick with overly aggressive blowtorch in the air intake. Also take off the air filter for torching or Wd40. Wd40 is also good if you have old fuel that may not combust as easially. Also place a towel above the starter so that you don't drip Wd40 all over the electrical connections (spark) of the starter.

I think the trick is how much fuel. I find that it will not start on full throttle, but 1/2 throttle.

It is a workout to get it started. It takes about 6 turns to get it up to speed, then drop the decompression while cranking and get the first compression to fire. I usually takes two or three tries.

I always used full throttle on the advise of the mechanic. BTW once you start it you might want to wander up to the cockpit and throttle down from 4000rpm in idle. Alternately you could shut it down after a few seconds with the decompression levers. Then do it again on 1/2 throttle.

BTW from your picture you'll never start the bugger. The top is missing from your Racor and you have air in the line.

BTW someone asked about where to get a handle. Your yanmar dealer will have one and since it's a genu-ine yanmar part is should cost about 1/2 as much as your boat.

Crank away!!!

PS The boat's name when purchased by us was "Fairhaven" and yes, the PO lived in Farihaven WA (Bellingham).

I've had problems with mine starting on full throttle, that's what the manual says to do, but I have found 1/2 to 3/4 works better for me.

Also I have read to NEVER use the decompression to stop the motor. I guess it will fry the seals.

Hi,

Last year I was on a boat with a small Yanmar engine. Hand cranking was the only engine starting option, it was not fitted with a starter motor from new as far as I know.

I can't remember the all the details but it had some kind of mechanism which held the decompression levers open. On about the 4th or 5th turn of the hand crank the compression dropped in automatically whilst you were cranking away. Had no problems getting it started. I didn't pay to much attention but it all looked like a genuine part of the engine. So may be it is available from Yanmar if you know the right question to ask.

Cheers
