Help, any Ideas?
2000 342 Performance. 2 years ago, rebuilt Starboard 502. It is like new, runs perfect. This spring I rebuilt the port 502, by the same shop that has been around for years and years with a great reputation. Sounds and runs well but will not make the same top end. WOT Starboard RPM 5000, Port RPM 4500+ almost 4600. We have checked everything and are out of ideas.
Help please
Thanks

I would start off checking fuel pressure, timing and take a look to see what the spark plugs look like.

Swapping drives will do nothing unless one of them has external damage.
Make sure the throttle cable is adjusted properly. Pull the flame arrestor and make sure the the throttle body flap is going to WOT. Unless the cable is hard to move, changing it will do nothing.
Did you check fuel pressure while running at WOT??

Another avenue to look at is the props....i had one prop from a set that were supposed to be 23p each......problem was that one prop had blades closer to 24.5P and it was loading the motor down too. They must have been worked at some point but you couldn't tell just by looking at them
