Mercruiser 454 to Volvo Penta SX conversion

[5andree]

Hello together.
I'm new in this forum and living in europe.
I want to change my 5,7 litre Volvo penta Motor from 1994 against a Mercruiser 454 gen IV from 1988. I want to add it on my Volvo Penta SX outdrive from 1994. I'm looking for a coupler which fits on the Mecruiser motor and on the splines of the SX outdrive.
Does any one know which coupler will work?
Thanks a lot
Andree

You might just be able to put the merc yoke shaft on the SX drive. Length is probably the deciding factor, they both use the same gimbal brg so that wouldn't matter.

I guess that could work, but perhaps there is a omc coupler which could fit.
Any ideas?

Ayuh,... Welcome Aboard,... Have you tried Any Couplers to test for Fit,..??

I would imagine the 1 from the 5.7 will fit...
