Were the parts you mentioned above on when you got the faster speed or did you instal these and then lose the speed?

no new parts just lost some speed

When was the last time your sc was rebuilt? Sounds like clutches slipping.

How are you measuring speed?

When was the last time you changed the plugs? how is the oil lvl? how old is the oil? old gas?

Take a good look in the impeller area see if you have some fishing string in there. Did you notice any water in the hull? May have a carbon seal starting to fail.
