Use Automotive CV Joint ?

ok, older Prout cat with a Nanni (Kubota) connected to an old Volvo Aquamatic 100 outdrive. In the course of having the outdrived serviced before heading to the Bahamas, found that both U-joints in the intermediate shaft were worn. Turns out that these are NOT Volvo U-joints but something smaller - no one here in the US has anything like them- had several people searching for me. Today someone suggested replacing the 2 u-joints with an automotive CV joint, thinking maybe a Civic CV joint a they should be common and not too expensive. The U-joint shaft has splines at each end so I might have to cut those off and have them welded to the CV joint. I know that the alignment/runout is critical but is there any reason this would not work? I am a quarter of the HP and not nearly as brutal as a front suspension. Plan "C" is to remove the outdrive and add an outboard to get us back into the water and out of the cold - wife has had it and ready to leave me.

Re: Use Automotive CV Joint- gave up

Just too many difficulties to overcome - bought a new outboard and will try to fix the U-joint issue at a later date.

Re: Use Automotive CV Joint?

Not uncommon in installations in Aus.

Something that can handle 200hp on the road will easily handle 30-50 hp of boat motor.

Last a long time and cheap.
