What is the Difference Between a Speedmaster 3 and a 3A? (besides the "A").
 
Have looked at a few boats with 3's and 3A's. Not sure what the difference is between them. Can you still get parts for them?

Lots and lots of information if you use the search function. 3's have a 19 spline propshaft
3a's have bigger bearings, gears and 26 spline shaft. That's the basic difference
