is that equal to saying a girl has a good "personality" ? LOL

Yes using GPS... Nothing at all wrong with hull...I am running with both fuel tanks full though... But still should be at least close to 70 mph.. I'm going to drag it by the shop in the am..we will see what they say...

Raise the jack plate when running at W.O.T and observe the speed and water psi. Trim it up and observe the speed. There is a sweet spot. But it sounds like it isn't getting full throttle or has a dead cylinder. It is down about 9 or 10 mph, something isn't right. I would check the throttle and see if it is getting fully open and check the compression.

Where is the water spray at ? In front of the driver seat, right next to it, or way back at the back ? Your set up needs to properly lift the boat. The right set up is a must because a Ranger is a heavy boat. How high is the rooster tail ? It should not be any higher than the top of the engine cowling ? It sounds like you are getting the rpm out of it but not the full thrust.

I have a 08 ZX225 w/yami 225 2 people hits 72 no problem,however when putting into gear if u don't put the throttle all the way down,it will restrict the speed.

This is about right....

You did not mention what RPM's you are getting.

He said 6000. If your tach is accurate I would start at the prop.

thanks guys.. i am going to have it checked out just to make sure its not a dead cyl. but im about 99% positive its not..the motor runs to smooth..

Wouldn't 60 mph with a 25 pitch prop twisting 6 k rpm be around 20-25% slip? Seems like a prop issue. Have you tried borrowing a prop from a friend?

The evinrude will turn a much bigger prop. Start with a 26 raker and go from there.

i took it by the shop today and they seem to think its a prop issue too... talked to matt at marine propellers in longview and i will be taking it by there asap... dont have any buddies that fish like i do or have bass boats lol.. but that would be a good idea.. we will see what happens and i will let you guys know what i find out... thanks for all yalls input

LMAO!!!

I agree with AstaSoftride.....If your getting 6000rpms your motor is turning where it should be. Can you tell if your prop is slipping? deff change in sound. I had a similar problem on my ZX250. My jack plate was too high. 1/4" down solved the problem. In my case I was running 3mph faster at 5500rpms than at 6000rpms. Also, I hade Steve rework my prop. He did a great job and helped me set everything up for my rig/load. Give him a call Steves custom props
