Saildrive 120s propeller.

Today I got our Bavaria lifted for the usual antfouling etc.... In our ownwership this I is the second lift for antifouling. The last time I changed the saildrive anode which required me to remove the prop. There is an Ambassador rope cutter installed.

Between the cone and the prop there is a tiny gap even when everything is tightened up. I noticed this time that when I grab the blades of the prop and give it a wiggle, ther is movement that I would not have expected I am wondering if the previous owner missed out a big washer/ spacer, it its meant to be like that. I have used the boat for two years with a lot of motoring and not noticed any problems.

As the boat is out now it would be good to know if the installation on our boat is the way it is meant to be - or not.

As always any advice would be appreciated.

Ta.

Seems like you are missing a large Delrin washer which fits between the cone and the prop. Essential as it is there to electrically isolate the propeller from the shaft via the cone. The prop has a rubber hub so the splines are isolated from the prop and the washer isolates the cone.

Thanks Tranona. Looks if it has not been there in my ownership, which is 4 years!!!

Fortunately, it has not caused any problems. Touching wood!!

One problem is that when removing the prop sometimes the thrust washer can stick on but be knocked if without being noticed an therefore you are convinced that there was nothing there

I have ordered a new one. Thx for the advice.
