have  a wake setter with the 383  hammerhead engine. this year it is lacking power. It used o top out at 52MPH, a couple years ago it was down to 42MPH,. and now this year it is 35MPH.  Otherwise it sounds healthy and no codes have been set. I changes the plugs a few years back, not much of an effect. Also changed the air filter... Is there an inline fuel filter I may have over looked. I'm thinking to check the compression and the fuel pressure. So I'm here to ask if anyone knows the fuel pump part number and if there are in line filters then those part numbers as well.   Any thing else to check? 

Two different size pullers. One for 1 1/4” shafts and the other for 1 1/8”. The larger will work on the small in a pinch.

It was to short from the back to the front of the shaft 

Thanks.  I don't ever get near newer boats, so I was curious.

No.  Moving the engine or strut would affect alignment. 
 

However, I’d look more closely at your weight, and your prop. Specifically the outer edges of the blades and the pitch of the leading (bow side) edges. Also, check the key between your prop and prop shaft.  
 

Are you sure you don’t have any buddies who were talking about how they loved your prop and maybe swapped it out for you?

In what way was it too small?
