Top speed???

Up north for the week. Took a WOT run last night..... 351 Windsor 13" 3 blade prop.

34 MPH is all she's got at about 3900 rpm. Seem too slow to you guys?

Yes you have a problem. First you should be turning way more Rpms then that.

Hole shot feels good, seems to have plenty of power. Overall I'm happy with the performance. 1:1 tranny...., something's fishy huh???

What's your pitch?

[biggsie]

Not too sure. Haven't looked into it. All I can read is 13x

I would look into a new prop, you probably have an original on the boat.

Regardless, should I get more speed?

You got a lot of factors here but yes, i run in the low 30's but my elevation is 8500ft. If your engine appears to be running good then i would suspect it is a prop problem, or a tired engine that needs a refresh. Have you rebuilt it?
