Well, the time has come to put out some really serious boat bucks. I am
about to order the Yanmar 4JH4. The clutch comes in two flavors, cone and
multi-plate. The cone clutch is about 3" shorter which would make life a
little easier but I am wondering what is the advantage of either type?

I will be using an Aquadrive cv joint/thrust bearing so there will be no
prop thrust on the transmission if that makes a difference.

No real world experience with these clutches but:

- I would suspect lower shifting effort for the multi plate
- I figure _maybe_ shorter lifespan for the cone, but you
would expect that Yanmar or the supplier has figured out to
design clutches by now.
