 I would recommend the traditional "C type" puller. My experience with the harmonic puller was well lets just say a waste of time and money. They say the harmonic type may not work if you have a damaged prop, but in fact it doesn't work on an undamaged prop either. I bought the acme kit you are referring to for about $99 and I was very disappointed; a nice bag full of cheap ass Harbor Freight tools. I picked up a puller from propellersonline.com for $70 and the prop was off in about 45 seconds VS. beating on the harmonic type for over an hour before giving up.

Sorry if this is a dumb question, but how do I check to see if it is fully open on the throttle position sensor and where do I find it?

Thanks, I was hoping someone would have dealt with the puller question already!  I think I will go traditional as well.  They sell an Acme kit with the traditional puller as well!

Yep, my two cents says you got a power problem. You'r 3 mph slower than me for every given RPM and your WOT is 10 mph lower than mine. That doesn't indicate a small amount of power loss...

If your effective ratio (tranny plus prop) were really taller than mine, you'd be running faster mph per rpm than I up until some point where it's just too tall and doesn't let the engine wind up. You're the opposite - you effective ratio is shorter than mine (I'm 3 mph faster at each rpm mentioned.)

As for the ptop kit - not sure how yours is but I got a case with puller, nut, etc. with my OJ and love it. If you are far enough from home, you'll want to bring that case on the boat. Last year we ran aground at 25 or so (mud, no damage whatsoever). Could easily have seen donning goggles and swapping props out there. The case protects your boat from the spare prop and I recommend one strongly.

This is good stuff.

Here is my two cents worth.

The harmonic puller worked fine for me.  One rap and the old prop came off.  As for the tools.  Well,  I agree with the Harbor freight comment. The ACME bag is not too bad though.

Capt. Rick - is there really a sensor for Open Throttle?

Finally,  I am not sure it is up to Derek's standards but here is the data from the prop change I made to my X-22.

[extruop]

I forgot to include running conditions. 

Full on fuel.  550 lbs of flesh.  No ballast.  Not glass but very little chop in the water.  I also tried to average running two directions.  It didnt feel like much of a wind but there was a full mile per hour difference between running one direction vs. the other.  That tower is a bigger drag than I would have guessed.

I think I am wide open on the throttle but I cant really tell.  Its quite a wild ride with the cover open at 40 mph and a little bit of chop.

For everyone else's benefit, here is Capt Ricks reply to my email on "how to check the throttle sensor."

Capt Rick,
You do it yourself engine off move shift to wot( wide open throttle) remove cable ball joint to see if engine can move more

After I replied, "What do I do if it can move more?"

Capt Rick,
The correct installation requires to check to make sure you have full throttle. The adjustment is on the cable loosen nut and turn ball( socket ).

Thanks again to Capt Rick for helping out!  I will try this the next time I get to the lake (probably 2 weeks).  Has anyone else tried this?

Love to see the data! Here's it plotted against mine and KTOWN's:

And after swapping axes....

I feel like I am on a spending spree!? Can't determine if the site is saving or costing me money?? After I hear about the performance/wake/cool factor that these upgrades bring, I can't stop from buying them.? I just bought an Acme 3 blade (#449 LH) which is a 13 X 12.625 X 1 1/8 and .080 cup.? I plan on changing my plugs and checking the throttle cable this week and testing the RPM's/Speeds again on the GPS.? Then add the prop and re-test.? I will post the results for all the data junkies out there!? Just in case anyone is looking, I picked up the Acme prop from a small on-line company called board it up.? Very friendly guy who runs the business from his house.? Drop shipped it direct from the factory.? Only 325.00 shipped to my house!?

On a side note, has anyone used an automotive tool to pull a prop?? I have heard rumors that some people use an automotive puller similar to the prop puller.? I have a sweet auto shop at my disposal and wondering if I could use something there instead of dropping the cash on a "prop" puller.? I know this defeats the spare prop argument, but might save me some cash for a month or two!?

I see no reason a traditional puller wont work.  Just be careful not to scar the threads on the end of the shaft while you are using it.

Check to make sure a standard harmonic balancer puller will work.
It is a little more difficult if you have a four blade.
A prop puller specific is the best.

I adjusted the throttle cable today.  It turns out I was missing a small amount of throttle at Max (aprox 200-300 RPM difference). 

Same data as before except I now have @4600 RPM WOT and max speed of 35-36 MPH. 

One question though.  Is the bolt that the throttle cable attaches to designed to move as the throttle cable moves (kinda swiveled).  I tightened it in a position that allowed full travel of the throttle (it no longer swivels), but want to make sure it isn't designed to swivel that way?  If so, I will loosen it up again. 

Changing my plugs this afternoon and hopefully the prop next week!  More data for Derek after the changes!

? ? Finally figured this one out!? It turns out that I had a cable on the opposite side of the throttle body that was not (completely) connected.? It was attached but not seeded properly (I will take a picture of the exact cable and post it!).? I don't know exactly why, but I believe it was causing my boat to go in "limp" mode.? If it indeed was "limp" mode, then "limp" mode rocks!? Other than the obvious distance to find usable power, it got me all the way to 4600 RPM and 33 MPH.? I now have almost instant power when the throttle is moved out of idle (I have to re-learn how to drive the darn thing).? The engine was turning 5300 RPM and topped out at about 36 in very choppy water with the ballast full!? Now that I know how this engine is supposed to work, I won't mistake this kind of problem again.? The beast is alive!? Thanks for everyones help and hopefully someone else will save some time (that I spent) by reading this post.
