05 pump upgrade results
Well I did hull truing and upgraded my 2002 GPR to a new 05 pump and DF prop. We were unsure where to start the pitch after comming from a 14.5/ 24 running 76mph @ 7150..
So I went to a 14/24.
The accelleration was out standing. 0-70 in just a blip. But I RPM'ED out at 7280 on a GK motor.. at a crappy 72.9mph I was just testing the pump and hull today. alot to go...
So what are your thoughts?

CARL. I was wondering if with a GK motor 7300 was the top? It doesn't have power valves to act as a rev limit? so what does?
Does the stock IGN?

I am worried that when I changed the pump, I DID SOMETHING WRONG??? But what would cause high RPMS and low speed?,, I don't know I am ready to send the whole pump out to have it checked?
I did the pump right to the setback Numbers? I double checked it!

It IS a new YAMAHA liner, so It is not worn.
