 Now I have finished the upgrade of the cone clutch using the upgrade kit mentioned above. Everything seems to be working fine. Totally the job took me ca 15hr. I had help from a mechanical workshop to make a recess in the top lid. The rest I did myself which normal tools and the instructions I got with the upgrade kit. 

You can contact Gideon at saildrives@yahoo.com

He is very helpful and willing to answer questions.

Total cost for the upgrade was $580 for the upgrade kit and $40 for machining + new gearoil. 

Hopefully I do not need to think of the cone clutch again. Time will show.

Congratulations, assuming you have got your clearances correct, adjusted the throttle linkage as advised, vented your gear case and are using GL-4 not GL-5 oil you should not have to worry about your cone clutch again for many years to come.

Thaks StavrosNZ.

With the kit you get a go/no go gauge. You have to sand down the top nut to the right tolerance is achieved. This is done by hand. It is a time-consuming part of the upgrade, but not really difficult. I believe i got it right in the end as the "green" gauge barely fitted after applying correct momentum on top nut.

So far it is working. I have to say I was a bit anxious the first trip, but after a couple of hours it still seems to be working fine.

Stephen, Toholthe - many thanks for one of the most useful series of posts on this forum; I'll get mine done before the next lapping is due but am fitting the vent sooner. The SD50 manual recommends replacing the entire clutch at 2000 hrs; I'm wondering if this upgrade obviates that, however?

Hi,

That is hard to say. If there is a lot of wear on the cone then only this part can be replaced I guess. There is a part on this in the instructions. My engine has 1400hr, but I had not significant wear. 
There is probably a lot of other “cover my a..” in the manual for the saildrive and engine you will never follow.

i just had my cone clutch replaced. I does not pay to relap. Mechanic did it in the water and I’d not have to remove motor. Cost $2,000.
