With the engine out, it seemed like a good idea (at the time) to fit an Aquadrive from Halyard Marine. This involves fitting a dwarf bulkhead for the thrust bearing at the inboard end of the prop shaft to be attached to. My problem is deciding what to make it out of and how thick it should be.
It will be between the engine bearers and will measure about 500 mm by 250 mm.
Clearly it needs to withstand the thrust of the prop pushing the boat along in all conditions and the instructions indicate that it should not flex in operation.
One idea is to make it out of marine ply (perhaps a couple of layers of 12mm epoxied together to make 24mm then glassed in place with epoxy and glass matt etc.
Another idea would be to have something cut/welded up in stainless that I can try to bolt in place between the engine bearers.
At the moment I am stuck in the stage of 'well that looks strong enough in my mind'.
Anyone got any experience/ideas?
Many thanks in advance.
