34/35 Prop Shaft Strut?

IIRC you have to remove the fuel tank to get at the bolts for the strut. Quite a project. I replaced my fuel tank several years ago.

I believe that you are correct... When speaking with Rudy, he indicated that IF the screws come out, and IF the holes are drilled in the strut exactly as the holes in the original strut, then I could simply screw in the bolts to reattach the strut. Otherwise, the tank has to come out, and the nuts, which are encased in fiberglass will have to be dug out. :wahwah:

I did not see on the drawings the alignment holes for the bolts to install the strut on your boat. Do you have to drill the new strut bolt holes?
You are correct - there are no bolt holes on the new strut. Rudy indicated that they were drilled when the strut was mounted at the factory, and therefore there is no standard location. My plan is to remove the current strut, insert short screws into the holes, apply paint to the screw heads, position the new strut and thereby transfer the location on the old holes in the hull on the new strut, and finally, drill the holes.

Also, the boat was hauled a week ago, and I was able to compare the new with the old. I believe that there are two fasteners that are holding the OEM strut to the hull, in addition to a generous bed of 5200 (or similar) adhesive. In comparing the new and old strut, I have come to the conclusion that, despite the electrolytic corrosion that took place, the old strut is still mechanically up to the task. There are no cracks or any signs of weakness that I can discern. Also, I am not looking forward to dropping the rudder, and draining and lifting the (full) fuel tank in order to replace the strut. I will
therefore hold onto the strut until I see any sign of weakness, or until I sell the boat (not planned).

Yeah, I guess after all the waiting & money spent you still have to drill the holes for the mounting bolts?

If the old one is still good why not keep new as spare? Good to know replacements are available. What was the cost? Will you need to remove the engine to remove the tank or can you just slide the tank forward?

I am keeping the new one as a spare (did I not say this?). I was able to source a replacement - although it took some time. I would not bet on being able to source one next year. When (if?) I replace the strut, the tank must either be lifted vertically or removed so that I can have access to the hull under the tank. No need to touch the engine at all. Right now the tank is full (I always fill it before I have the boat hauled), so lifting the tank would be more complex than if it were empty.

I think the tank will have to come out to access the strut bolts - I just removed my tank last weekend, major pain if you don't want to cut fiberglass (I cut the tank). I don't think lifting it will give enough access as there's only about 6 inches of room above the tank.

Given the corrosion that occurred, do you think it would be worthwhile to attach a zinc to the strut?
