1947 Century
My good friend's father in law just finished restoring a 1947 Century. The boat is beautiful (awaiting pictures). The question that has been presented to me is how to connect the engine to the prop shaft. I feel the engine that is going into the boat may not be original, hence the driveline issues. I know the trans is a Velvet drive, but don't know much about the engine. It does have Offenhauser valve covers and a very low profile dual carb intake system.
Any guidance would be helpful. Thanks in advance.

The prop shaft should go directly into the transmission coupler and held there by a pair of set screws as well as a keyway. http://kfulford.globat.com/SkiNautiq...ter_hookup.jpg

needless to say, the coupler has to be the correct size for the propshaft. so first get shaft diameter and see if keyway has been machined into it. shafts are usually on even 8ths of an inch. 1-1/8, 1-1/4, 1-3/8ths or in this size boat mebbe 1 inch even. see if velvet drive has flange on back that looks like it will match up to payupp's pic. it should. unless it has been removed from trans.

There's definable a flange on both trans and prop shaft. I guess the issue the owner has is the height of the engine in the cradle....he feels it's too high. He wants to add a u-joint to the prop shaft and the trans so he can lower the engine in he cradle.
I'll try to get those pictures today.
