YANMAR 3QM30 with KH-18 - $1100

I have a relatively low hour 3QM30 in my warehouse that I bought as a spare engine and for any parts I would have needed. When I bought it, the engine hours were estimated to be about 2200 hours. It started and ran smoothly on the shipping crate when I received it. The transmission was reported to be sound and not slipping. I am selling this as the buyer of my boat with her 7,500 hour 3QM30 said he didn't need it. Message me for more information.

I'm hoping this is reasonably close to Detroit... ?

It's in a crate in Little Rock, AR, and can ship LTL. If you need photos and live video viewing, that can be arranged.

I forgot to mention this engine also includes a young set of analog instruments for oil pressure, temp, voltage etc.

I sent a DM, but i'll also ask here for extra visibility to others:
Is the the raw or fresh water cooled version of the 3qm?

Good action, but so far, no takers, so now the price has lowered to $750.

Quick way to find out if you are in the ballpark is to compare the old engine's transmission output flange centerline to engine mount height dimension to that of the Yanmar's. You can do this using the engine literature drawings. From there you need to check where the engine will sit longitudinally with the prop shaft in position and if there is enough space forward of the engine, enough height and space port/starboard. The Yanmar's output flange is perpendicular to the engine mount pads but some transmissions have angled output flanges that may be a factor.
