I have a running pull out I have yet to advertise. A yanmar 3Qm30H 33hp with gear, panel and muffler. I have a shaft & martec prop to go with it. No hour meter but I would estimate 2300 hours. Ran very nicely and used .75 GPH to power a 21000lb sloop. This boat goes offshore for racing and a newer, lighter, more powerful 47 hp yanmar was installed. The old engine primarly powered the boat out of the slip and into the bay where we then shut it down and sail. We used the diesel mainly to charge the batteries while underway.
I have considered keeping it as a means to produce power via a generator for my home because I am concerned with the Cap & trade legelation currently being debated.

The reasons for changing it out are simple... The engine & gear weighed 590lbs The new one weighs 420lbs. The engine needed a simple repair to the block that could not be done on the boat. It did not make sense to pay all that money for the crane to lift it out of the boat and take the boat out of service for that long without entertaining the logistics of installing a new one. The use of the boat has changed and now does more cruising and was in need of larger diesel that produced hot water for showers & heat for those fall and spring weekends.

Please contact me if you are interested. By the way the head on the engine was changed out about 10 years ago with a brand new one from mac boring in Union Nj. seems there was a zinc that did not get changed with all the others. This engine is all cast Iron but the pan is a machined aluminum. also have spares .. Injectors, gaskets etc

This is a ready to run diesel with a gear 2:1
