Looking for advice

2005 is just now getting broken in, for a Yamaha at least. I had a 1986 Yamaha on one of my V's and when I sold that boat and bought another one it had a '99 Johnson. That '86 Yamaha ran circles around the '99 Johnson. Had not one problem w/ the Yami and from day 1 that damn Johnson was unreliable as hell. So keep that '05 Yami until it dies. Good chance it'll outlive all of us here the way those things run. I've got a 2001 that runs as soundly as it did on its first run. I have no clue if I'm running the right prop though, so you're not alone there.

About the best way to check the efficiency of your prop is to find out the mrgr's max RPMs for your motor...for instance, mine is 6,000 @ Redline...the prop you're spinning should allow the engine to go to it's MAX RPM at Wide Open Throttle (WOT) w/light load, min wind and current (and top down if bimini)...if it goes well over the max she's propped too high...if it won't achieve the max, then she's propped too low...hope this helps...the wrong prop will over load the motor and keep you from gettin the best fuel mileage...mine is not quick outta the hole, but set up to cruise at max fuel efficiency...hope this helps!!...

And also remember... Pitch, Diameter and number of blades ALL contribute to your boats performance. Like Reelapeelin says.. get the one that does what YOU want it to do. Keeping in mind that constant overrevving or lugging your motor will contribute to a shorter lifespan.
