I can't get the RPMs out of it.

I just moved it from another boat to a 21' barge.

The motor shutters and won't get to full RPM.

I have a 13 pitch prop on it.

If I get a 9 or 10 pitch, will this help it?

Good compression, good plugs, good fuel, good injectors.

It ran good with a 15 pitch on my former duck boat...
