Looking for advice

[Blue_Runner]

I have the same engine one year older but I bought it new in '05. I agree with all the posts .... except Willy's

Run it til it dies. That is what I'm going to do. I don't know how many hours mine has but I'd estimate maybe 2x as much as yours? Honestly I don't know but it has done everything I have asked it to do and more.

So yer gonna keep 'er...willy will be heart-broken...

I believe a deep V needs a large diameter prop to properly PUSH the hull thru the water...the more V, the more water surface is in contact w/the hull...I tried a 15 1/2" dia X 17 p Mirage when 1st got the Honda, but it was too heavy and actually caused a rattle in the lower unit at idle-speed...got a 15 1/4" dia X 17 p X 3 blades from Power Tech Props made for Honda...have not looked back since...props these days actually have bow-lifting or stern-lifting tendencies...V-20s generally ride bow-high to begin with, so if I were looking for a new prop today, I'd be looking for a stern-lifting prop which willl smooth the ride out a bit...which may take you in the direction of a 4 blade prop...

The is a great book out on propellers that you can buy from Amazon.com for around $14 bucks.. cheap at twice that price if it saves you from buying a $500 mistake.

It's called "The Propeller Handbook" by Dave Gerr

A must read for anyone contemplating buying a new propeller! In fact, you can even read several dozen of the pages by going to Amazon and clicking on the book and then clicking on the "See inside" tab.. or you can simply click on this link to get to the same place:

Although you cannot read the whole book, there are enough pages that are displayed for free to give you a really good idea of what you should be looking for and why things work like they do when it comes to propellers.

Another way to go if yer gonna spend big on a prop is thru www.ptprops.com Power Tech has been at it for a while...they speced the 4 blader for my buddy's 24' Everglades and NAILED it first shot!!...and had a hand in selecting mine...if they don't get it right, they'll swap...good folks...

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.
