My LF38 has the QM series. But it is also hull #4. I am not sure when they
quit using the QM. Doug MountjoyS/V PegasusShilshole bay marinaSeattle.

how bad is it really?The difference between the GM and HM are negligible.
Most/many parts are interchangeable. The HM only came in 3 cylinders and had a
slightly higher power rating. The F designation means that it has a glycol
(fresh water) coolant system and heat exchanger. The GM came in 1, 2 and 3
cylinder versions in which parts were directly interchangeable. Visually I
believe all of the GMs have a place where a handle can be attached to the front
of the engine to presumably hand crank. I have a Yanmar service manual that
covers all of the HM and GM variants.Not sure about the QM.As for access I
enjoy 3 sides but could survive comfortably with just front and back. Front
alone would be quite challenging. Josh Muckley

I took a look at a Landfall 38 last week, and yeah it's pretty bad (engine
access). But does it actually prevent you from doing any critical tasks or is
it more of a nuisance?
Also anyone know the differences between the Yanmar 3QM30F, 3HM30F, and 3GM,
either in terms of size (access) or power / longevity?
The boat I looked at had the engine recorded as HM, as either a correction or
upgrade (to a survey which indicated it was QM), but the owner said on this
forum (a few years ago) that it came with a GM. The broker said it has the
original engine. So this is very confusing/misleading, but will try to clarify
with broker which it actually is.
