Prop removal questions...

A new Acme 422 was delivered from Delta this morning. I'm still at work, but look forward to installing and testing it this week. I'll get a photo of the "wedge" and post. (it's the size of a fingernail)

This will replace the stock prop, which I drove onto the mud flats while seeking "smooth water" for my 9 yr. old. She was on the boom, and just got up on the trainer skis.

Ed,
Post a picture of this "wedge". I don't know what it is ether. Is it a brocken piece of the key? Some were tapered on the front ends.

For what it's worth, I just used an Auto Zone tool loaner propram pulley puller to remove my stock prop from a 93 SN. 50 buck deposit, zero cost to me after I returned it. It was a tight fit, but it worked.

It took longer to jostle the puller and prop to a location where all the bits would clear the rudder. After that I put the screws to it and the prop broke free with a big bang after about 2 minutes and and 3 turns of the screw.

I was left with three pieces: the prop itself, the "key" and a little wedge. Where does the little wedge go, and what is it's purpose?

Thanks,

Ed

Did I mention that It's my bachelor party? Haha let's plan on sunday!

Awesome Steve. By the way, we have the 1442, NOT 1422 (if that's even a prop ACME makes)

Dad said we have 1.25" between the blade and glass which is plenty of room IMO.

We also have a 654 I may try if I hate this 1442 (I didn't like the 1442 on the 90) reason being I think is because the 90 didn't have enough power to turn it. I don't know.

I have my bachelor party on the 18th but we will be skiing Sunday the 19th for sure. The bach party will be around town so if you're in the area whatever time works come on down. Sunday would be our best bet though!

I'd love to post on tach numbers but after our new gauge install our tach has been flakey....we need to have our Marina check it out again.

Steve, ACME 1442 on 2000 Sport Nautique GT40 Perf testing will begin promptly tomorrow morning at roughly 9AM CST.

I will report back on my findings. From what I understand there aren't many 1442's on Sport Nautiques. Should be fun to see the numbers and feel it! (feel the power and the prop) Can't wait to see how smooth it'll run, hoping it's better than the stock job. We have a tiiiny bit of mirror wiggle with the stock prop.

GOOD NEWS!!! Dad just texted me (he's off today)

"got the prop off, heated the crap out of it and invited Joe and Moe"

While blowing kisses to his arms he likes to say "once you meet Joe, you don't want no Moe"

Goofy guy yea? Heat was the answer I guess!

i keep using the steel plates for other projects, and my machinist keeps bugging me to come in on Saturdays to finish them up. i will eventually build them...lost a bit of fire over the years.....

...sign me up. I just picked up a puller but will always buy whatever eric is selling.

Doug,
Here's one of the threads the puller came up in: Build your own prop puller towards the end of page one.

With the C-clamp style if it doesn't pop off after ther first 1/4 turn I'll take it off and rotate between blades. Only once did I have to use a little pursuasion.

Mark, what is that number based on?

I agree with HW. Tighten, wait, retighten. If youre in a rush, a single hammer blow to the back of the puller will usually do the trick.

Mike I had the same feeling with the original prop. It felt like it was using far too many rpms at speeds above 30mph. This was comparing it to my 89 with the 422. I decided to change the original prop (OJ 13X16 4 blade) with the 422. The results were disappointing in that the rpms only went down 100-150rpm at 40mph.

The original prop was also very tight on my boat it bent my g clamp style puller so I made a quick copy of Pete's puller and it came straight off.

I think the larger hull does require more thrust to get it through the water. I was just not used to the extra rpms required. Remember the GT40 is good for 5200rpm.

Overall I think the OJ is a reasonably good prop for these boats.

Looking forward to you testing the 1442 on this hull. Get the speed and rpm figures at reference points with your current prop before changing. I regret not doing that myself. One of my winter projects is to back to back both props with full data.

If you do, please do down in pool13 and not 12. That will give you plenty of time for that flatty to catch you. You don't need to repeat the "Tx Damn Test"

In the back of my mind I knew it was gonna be an awful deal, but was hoping by some miracle it'd just pop off. Yea right.

I hate the prop that's on it now. Motor turns great with it, problem is you don't go anywhere! It's like it sits there and spins
