I didn't mean to imply that it just sits... I do start it and run it
for 10-15 minutes, either because I haven't run it in a while or
because I'm going out or coming in. Does that make a difference? I
don't mind changing it myself. The hardest part of doing anything with
the engine is actually checking the oil. The dipstick is in on the
starboard side about mid-engine, but the engine is offset in the bay,
with the forward part inset to starboard. So, basically, I have to
reach around it to get at the stick, which I can't see directly.



One of the very important things you can do for it is to take it out and
toss caution to the wind and run the hell out of it for 10 miles. 15
minutes isn't long enough to boil the water out of the crankcase. You
need
to run it hard and hot for that, raising the oil temp above 212 to boil
off
any water that may have accumulated, even from just condensation, in the
crankcase. Exhaust water cooling gets back through the open exhaust
valves, condenses in the cold block and always ends up in the
crankcase....under the oil where the pickup tube sucks it into the oil
pump, of course. It's not a serious problem, but is so easy to avoid by
simply running the engine for further than just far enough away from the
dock to get the sails filled. Run her out on the engine, not at idle, let
her breathe at cruising speed...way up there....above 2000 RPM. She won't
explode.

If you haven't run her hard in a long time, set her on 2500 RPM and let
her
run an hour. It's really good for it.

.....and, no matter what you may have heard, it's not mortal sin!...(c;



A couple of things... the engine temp never seems to get over 200 no matter
how long I run it nor how many Rs. Hull speed rpm is about 3200 or so...
can't remember exactly, definitely over 2500. No smoke out the back, so I
know I'm not doing harm. I do this if I happen to be fighting the current at
some point.

end of the sailing season

End of the sailing season?? Huh??

Sailing season never ends....does it??

How silly.....

SAIL SOUTH!! SOUTH!!

We'll leave the dock lights on for ya....

New Years day, Charleston Harbor, RACE DAY!!

End of the sailing season....yecch.



Well, maybe I should have said end of the primary season... typically
December, and I sail only occasionally in Jan/Feb, although this year
several times.

Ok, so what you need to do is to start changing oil at least every 4-6
months.

Once a year is plenty on a small engine that doesn't get run very
much.

I usually do it in panic as the tide we underestimated it dragging us

The coolant temperature isn't what's important. The CRANKCASE temperature
is much higher, the oil cooling the bottom of the pistons splashing around
in there. It's easily over 212F in the crankcase.....

Global Warming is only a downside if you're depending on government grant
money to study it, ad nauseum.

Unless you're an Amsoil dealer, whos company only has REBOTTLING plants,
not any kind of oil refinery or synthetic oil manufacturing complex.....

http://www.yanmarmarine.com/
click Questions and Answers
on the left panel is maintenance videos.

Ignoring that he didn't TIGHTEN the "radiator cap" when he told you to, I
stand corrected by Yanmar. Oil change interval is 250 hours or once a
year, now.

I also think the video violates the Magnusson-Moss Warranty Protection Act
(15USC50 section 2300) in that he specifically tells you to use ONLY Yanmar
BRANDED impeller, oil filters, air cleaner in this video. According to
FEDERAL LAW, Magnusson-Moss REQUIRES Yanmar to provide ANY part they tell
you MUST be a Yanmar Branded part.....FREE for the entire life of the
engine, not just to the end of the warranty. He's more vague about fluids,
telling you to use Yanmar or "approved" oils, transmission fluid,
coolant....

So, I guess, once a year is now OK.....at least for those selling engines.

Do all Perkins 4-108s smoke like that? I almost bought a boat that did that,
but it smoked at all rpms, so I passed.

I'm in favor of global warming wrt to sailing, but that's it.

At the risk of being shot down, I would say that it's cheaper to change the
oil than send it away for testing. With my BMW only doing 3500 miles per
year due to UK gas prices, I simply change the oil every 6 months regardless
of manufacturer's recommendations. Doesn't the same apply to boats?

Of course it does and all the rationalizing in the world doesn't
change anything. Oil is cheap and down time and repairs are expensive.
When I was working construction jobs in the jungle we changed oil
weekly on the earth moving equipment working 24/7 and monthly on
cranes and other less used equipment. Our re-supply time was about a
month and down time was far more costly then a few gallons of oil and
a couple of filters.
