New to the site... I am not a racer like you guys but I was curious about sport c boats and I had some tech questions that I thought a few of you might have some insight on. I was trying to replace the propshaft seal on my 40d and things went bad starting with the first bolt. I have a 40c and 40d I know the lower units are different just buy looking. My question is are the hubs for the propshaft (that hold the propshaft needle bearings and lets the exhaust out) the same?

Just out of curiosity which motor is better? the 40c or 40d???

Thanks in advance
Riche
