Hello i have a old 2qm15 for sall in marathon fl #05 9000499

So far we have found a siezed water pump (replaced), Bad Fuel lifter (replaced), and finally (hopefully the last) the injector pump is only feeding fuel to on of the injectors. THe mech says it needs to be recalibrated...

Total cost so far:

Fuel lifter = $200.00
Water pump = $ 80.00
Labor @65/ 7 hours = $455.00

The key thing is I watched everything he did and learned how to diagnose this type of problem in case of future re-occurance.

Hopefully after today I will be on my way to Key Largo...(10 hr run from Miami)

BreakingWind2 Noreaster,
Thanks for the links. I think it is the regular 2GM.

A friend of mine

recently ran into the exact same thing. He had one and book kept saying it was something else. He figured out that there were some engines not intended for use in this country,that were labeled differently. His was what the book said it was and what it looked like, but was tagged as the other.

Northeaster Breakingwind - Do you mean a regular 2GM (which is 15 HP max, 13 HP continous), as I have never heard it described as a 2GM15. The regular 2GM manual is likely what you need.

another link!

BreakingWind2 Thanks NOLAsailing,

Just what I needed.

NOLAsailing No problem guys. When I bought the boat, I had a hard time finding the manuals. I finally bought them off Ebay from some guy in the UK. When it arrived, it was just a burned CD with the two .pdf's on them. I decided that was ridiculous, so I uploaded them to my website so those that need it can get it for free.

As for the 2GM, another J30 owner has the manual and EXTENSIVE, photo-documented 2GM info on his site: Rhapsody J/30 #348 Yanmar 2GM Rebuild

Ditto for me! I just bought a new-used boat and it has a 2QM15. Thanks for the manuals!!!
