Sterntube removal

[BASS]

I need to repoistion my sterntube in order to swing a bigger prop. The engine/gearbox are in situ. Is it possible to fit a flexible coupling or do I need to lower the engine? The engine is fitted "back to front" with a v-drive. Any thoughts apprieciated

HAd to put mine back in when it came out in my hand this winter! on a GRP hull it isn'ttoo big a deal. I slicedof the rear section of the deadwood so that i could glass the stern tube to the inside face - therefore not covering up the thread the cutlas bearing sits on. I then bolted the whole transmission back together, and (epoxy) glued the severed section back on, held in place with gaffers. when the thickened epoxy hadgone off, I ground back around the join and went over with plenty of glass and epoxy.

of course if the boat's not plastic that won't help much...

Thanks for that. The boat is GRP. It is a 28ft Aquabell. It has a shaft approx 11ft long.

a flexible coupling will not do what you want
you would need aqua drive assembly to take up that amount of miss alighnment

could you use a 4 blade prop
talkto a good propeller supplier

Thanks scottie, I already have a 4 bladed prop with a 21" pitch, so am on the limit now. I think the original tube was installed to high, so I think I have to lower it. I really want to know if it is feasable or not without engine removal
