I have a 1991 caravelle it runs perfect on muffs when you put it in the water and accelerate it just stays at low rpms I can't figure it out I rebuilt carb, new cap and rotor new plugs cleaned all fuel lines

Sounds like something timing could do. Did you follow the manual on setting timing? Merc has very specific method.

You'll find it. Good luck.

I checked the timing it was good I thought it may not be advancing the timing but don't know what controls that

There are weights with springs under the distributor mounting plate that advance the timing. I had an issue with my distributor being rusty 'under there'.

I have pics somewhere in the link.
