Yanmar 2QM20F, walk away?

I'm looking at a Morgan 32 with a 2QM20F with around 1100 hrs. The broker pointed out to me it is an older model yanmar and the parts are harder to get. What are people's experience with getting parts and working on this engine? Should I walk away from the boat based on the engine alone?
(Not not a mechanic but I have experience working on and doing maintenance on gasoline engines. I'm ultimately hoping to take the boat to the Bahamas)
Thanks

New parts for the QM series are just not available. the only source are used parts and hard to find. if it only has 1100 hours it could be in good shape and runs for several more years. but in a few years it will be even harder to sell the boat with that engine.

FWIW I've been able to get the usual maintenance items, filters, thermostats, impellers, gaskets. even a new mixing elbow last year. Mine is 1977 with ~2800hrs, I plan to run it as long as it is reliable. I know that the transmission is NLA (~8 yrs ago I replaced the transmission with a used unit that I found on CL)

I don't advocate using the global health crisis to gain an economic advantage, but, the odds are that boat prices will be dropping. Either wait for a better deal, or use that information, and the issue with parts on the engine, to negotiate a better price. Even if you find another boat with an engine that has cheaper parts, it could still die on you (then it doesn't matter what the part price/availability is because you are repowering anyway).

What year is it? My 2gmf13 is an 82 and runs beautifully (knock on wood). The usual maintenance parts have all been available including oddball sensors and what not. If I needed to tear down and rebuild it would I be able to find sleeves, pistons, etc I don't know. If the day comes for a rebuild odds are I'd just replace it anyways.

My hour meter has been replaced by a PO, current one reads about 650hrs of which I put over 500 of those on. Just finished my circuit of the Bahamas and we started in the great lakes. Currently anchored in lake worth after over 3000nm logged and headed north again starting tomorrow. Oil changed and usual stuff checked, she starts right up.

Some youtube videos, nothing fancy

If it is running OK, then run it. It is still possible to find spare parts for these older motors.

35 hrs per year. You have to figure a number of things . One is that realistic or fudged. Thatís a couple of hours a day would be 18 days of use per year.
Seems a little low,

Diesels like to be run...did this just sit for a long period of time. Are there any records. Iíve got an original Yanmar 3gmf. Itís well over 6000 hrs and runs like a top. I am itís history so I know itís been regularly maintained.
