I just picked up a project boat. It's a 1971 Mariah with a Oldsmobile 455 and a Jacuzzi pump. The issue is I'm new to jet boats and it appears I'm missing the Bell housing/rear motor mount and whatever it is that attaches the motor to the splined shaft for the jacuzzi pump. I have been able to find the Bell housing on eBay but my ?? Is what is it that I need to to mate the 2, together. Thanks Dustin
