Yanmar 2cyl auxiliary engine - boats - by owner - marine sale
This is a running engine that is still in the boat. I can send a video of it running, or start it for you. Price includes everything except the propeller. Fresh water cooled. Selling at a price...

I suppose if I was flush with $$ I might go for it and get the extra HP. The guy is looking for $1200 which is about what my 1GM10 cost me. Of course the 1GM10 was a never installed engine until I dropped it into my boat.
If you have an E-27 to maybe 35 and need an engine this might be worth a look.
