Hi everyone
I feel like a little kid. All I seem to want to do is see how fast I can get this thing to go. Ahhh life's simple pleasures.
My wife, would be happy just bobbing around and talking.
Maybe I like the speed because it is too loud to talk over?!
Anyway.
The boat is a 1987 4 winns 170 horizon with a 4.3l 2bbl carb and a mercruser outdrive.

With the 19 pitch prop top speed with two people and a dog was roughly 40 with RPM too high (5200!)
With the 21 pitch top speed is 43-44 with two and a dog at 4900rpms
Do you think I should go to a 23 pitch?
Is something wrong with my boat, or is it just perhaps a bit tired?
Some claim 50mph from simmilar set ups
