A 13x13 prop is standard issue on 89 prostar 1:1 transmission equipped (not a power slot), so yes it should work on a 1:1

A power slot used a 14 x 18 & has a 1 1/8" keyed tapered shaft.

The Acme 425 LH 13x13 will work for your PS....

I bought a lh 13x13 1 inch for 100 bucks. Are you guys thinking this will work? I have read different things. I'm trying to save a little money. I will be pulling kids on skis and wakeboards.

I will be pulling kids on skis and wakeboards.Here's the real deal..... You have a power slot tranny. It will have a 1-1/8" dia shaft. The prop you bought will not fit.

You can use a 13 x 13 or any other pitch prop, but the bore has to accommodate the keyed shaft (1-1/8").

Are you certain that the one you bought is a 1" dia bore? If you bought this one ( http://www.ski-it-again.com/php/skiitagain.php?topic=Search&category=Propeller&postid=23869 ) it is the 1-1/8" bore it will indeed work for you.

Slow down a little on this boat and read for a while, then go forward. Read the correct information, but also post the correct info in your inquiries.... You're on the right track. The 13 x 13 x 1" LH should sell easily enough at $100 and shipping (makes a great spare).

I hope this post is approved as useful....

Am I missing something? On my 1987 PS 190 Powerslot Acme recommended the #275 or #381.

The 275 and 381 are 13.5 x 17.5 with minor differences in cup.

Cloaked is right, you absolutely need a 1-1/8" bore.

The thing to do is call Acme and ask them which prop they suggest.

Catamount which one did you go with and why? I pull mostly wakeboarders and usually have a several big people in the boat. Thanks for your help.

I would not CONSIDER 13x13 on a powerslot boat.

The 14X18 moves 18" forward through the water per revolution of the prop - minus slip.

The 13X13 moves 13" forward per rotation - minus slip.

A powerslot is a 1.5:1 transmission, therefore for every 3 turns of the engine the prop turns 2 times. That means a 14X18 moves forwards 36" per 3 turns of engine and the 13X13 moves forwards 26.

Compound that with the fact that a 14X18 should in theory be more efficient (less slip) then you'll have to consider that the 13X13 really won't move the boat forwards through the water like it oughta.

Full truth is as long as the prop has the correct bore for the diameter of the prop, and so long as it is keyed instead of splined you can put it on - might not work very well - or be worth 100$

The first thing I did was call Acme. The guy I spoke to was incredibly knowledgeable. Asked me about which model MC I had, which engine, what my elevation was, how many hours on my engine. He recommended either the Acme #275 or #381 (I think... you should call & confirm).

This was my old prop. With a Powerslot, you should have had a 14 x 18 on there originally.

This is the #275 Acme I replaced it with. I have since had to ask my driver to ease into the throttle on deep starts so my arms don't come out of their sockets.

Acme recommended a 1591. Anyone used one?

1591: 14 x 16 - .135 cup?

I haven't heard any mention of that prop on this forum before.

Acme recommendations are very good. They were spot on for me. I ordered exactly what they recommended. And at 4000ft I was getting 43 mph with 5 people with my 91 super comp. which is what it did at sea level when it was new in 1991. I am happy with the product and recommendations from acme.

Agreed, they know what they're talking about.

Fishnhunt, it would be great if you could give us the reasons Acme recommended a 14 x 16 - .135 so that people looking for a prop in the future can reference this thread.

Thanks.

I have a 89 prostar 190 with power slot. I told them I pull mostly wakeboarders and usually have 3 to 5 people in the boat avg weight per person is 180 lbs. they felt like this prop would have great low end and acceleration. He asked how often I would run full throttle and how important top speed is to me. He said my top end would be around 44 mph. I asked about the 275 and 381 and he felt like this was the best choice. I hope this helps.
