My "new" paint job is 8 years old and some areas are no longer shiny due to
strap tension on the winter cover, so I was wondering if a simply wax type
finish or a touch up paint job is in order. Saw some earlier posts, but wanted
to weigh in.
Thanks,

Not C&C related, but certainly maritime related - dramatic story about the
El Faro, a 1970s container ship that was lost at sea on October 1st, 2015

Hope all you C&C'ers are well.
Bill, my old 3qm30 had 2 thermostats. My understanding between the raw water
cooled and fresh water cooled is the opening temperature of the thermostats.
This was from my local Yanmar dealer.

Have Yanmar 3GM and Kanzaki transmission. Had similar issue of only one blade
opening after sailing, boat shaking and continuing problem after trying varying
speeds, reverse / forward etc. Worked fine if starting from dead stop. Not
excessive wear on blade pins. In our case turned out to be
Got it, thanks for your input...

Martec non-geared props have issues with both blades opening especially if they
get worn at the pin in each blade. Sounds like that might be the issue. Was
on a J/35 in the late ‘80’s that had that issue and the whole boat would shake.

Pretty sure it's a martec, folding 2-blade. I try to power up and it
vibrates like crazy. I power down to try and get it to reset so that I
don't damage anything with it vibrating so bad. Then I try again. If I
rotate the shaft manually I can hear each blade folding open but for some
reason it is t
Josh,
Thanks, but I must have older or newer than that diagram (1981 boat). My
thermostat housing is on top of exhaust manifold, square in shape with 4
distinct chambers, two of which are machined to accept thermostats..
I think I will just leave as has been for the 7 years I have owned boat
I’m curious. What kind of prop do you have that requires you to slow down to
get it to open. Most folding ones ask for more speed to get the blades to open.
Non opening would produce lots of vibration, which would get lots of noise as
the engine bounces around on (particularly) old motor mounts.
Bill,
Check out page 162 in the following link. On page 182 it describes the
thermostat setpoints. 160 = fresh and 108 =raw.

So your engine IS raw water cooled. This confirms my suspicion that the
dual thermostat is part of the raw water design of the HM/GM/QM series.
Typically the raw water thermostats run cooler than the fresh. This helps
prevent localized boiling and scale formation in the engine. I believe

Josh,
I have a drawing from yanmar manual, not quite same as yours. My thermostat
cover has bolt pattern different..fore and aft and side to side..I am always
confused by "raw water, fresh water" thing...I draw lake water in and through
engine and out...no antifreeze or heat exchange..just
Is your engine fresh water or raw water cooled. By the model number I'm
guessing that it is raw water cooled. I don't have the manuals for the QM
series but believe that they are the predecessor to the HM and GM. As such
many of the parts are interchangeable and much of the design is the same.

Good morning,
Yesterday I removed the thermostat cover on top of the exhaust manifold to
replace the thermostat which I suspected was bad. I have a yanmar service
manual which has detailed drawings of the exhaust manifold on this sea water
cooled engine. To my surprise when I removed the c
