Advise on Motor Oils for Wet Clutches
 

Ok, a very nice person read my post here about our
clutch slipping and recommended looking into the oil
we are using. I've been doing some research but
figured I'd also post here as it may interest others
and I know there is a wealth of knowledge here.

Situation: Our 1958 Chris Craft has a 6-Cylinder
model "M" engine. It has a Paragon transmission
that used discs (not gears) to engage power.

The transmission does not have separate fluid, but
uses the same motor-oil as the engine for it's lubrication.

When we get the boat up to about 2500 RPM the clutch
momentarily slips. We do have some instructions for
how to adjust the clutch, but it seems very hard to put
into gear already -- as if there is already plenty of
pressure on the plates.

What has been suggested is that newer motor oils
have more "anti-wear" additives and that these may
actually coat the metal-to-metal parts to keep them
from wearing. But in our case we *want* the metal
to metal parts of the clutch pressure plate to come
into contact with each other and *not* to slip past
each other.

Anyone have knowledge or ideas about this in
general and/or about Paragon transmissions?

Also, any recommendations on specific
motor oils to use that might be better for us?

Thanks,
Gary

Well, the bad news is you're due for a set of clutches. You can try to run
some Marvel Mystery Oil in the oil, might help you out, but if you're
already tight on the adjustment and still getting some slip, well time has
come. Good news is it's a pretty easy thing to do and not very expensive. I
believe the parts are still readily available.

What was the oil specs for the motor to begin with? I'll bet it was
straight 30W non-detergent. If so, that's what I'd look for. If it is
slipping badly, I'd bet that it needs adjusting, and I don't think
that adjusting the clutch will make any difference in how hard it is
to engage.

It does on those, it's a mechanical over center engagement lever system. The
oil is mearly there to cool and reduce the wear on the clutches and to
smooth the coupling transition.
