I picked up a 89 Prostar last year as a second boat, strictly to use to slalom ski as a family.
We've truely enjoyed the time on the water with it, and while I wait for the ice to melt up here, I'm thinking of some possible upgrades. The boat is a stock 240hp 351, running stock prop.
We run the course with it, and are very happy with it.
I'm considering adding perfect pass to it or a Acme 541 prop. No real reason to HAVE to have it, but wondering if either of these 2 upgrades are really worth it.
For now, the prop seems to perform just fine, and the boat holds its speed manually through the course pretty good.
Waste of $$ or worth while upgrades?

Those are the two best upgrades, of course pp is the better of the two. Only thing I will add is I prefer an oj prop. Prices are all about the same and oj has better customer service and that's original equipment for that boat. 13x11.5 three blade CNC is the ticket for that boat! That's assuming it's 1:1. If it's a 1.52:1 powerslot, I think the stock 14x18 three blade is always great, with the 14x18 four blade being a bit of an upgrade.

Between the 2 options, I'd go with PP. Consistent pulls, and ease for the driver are worth it, even if you're not skiing tournaments.

PP just makes it all easy. It's what we used to keep the skier from trying to blame the driver for a bad pass.... :-)

That would be my first choice and would probably be worth something on resale or at least be an option to help sell the boat if you decide to later.

I'm swinging an ACME 541 on mine and wouldn't put anything else on it. I had OJ's before and there was always a sight vibration. Just saying. Maybe only a quirk but paranoia does come into the equation. ;)

+1 on everyone's input so far.

The 541 will perform much nicer and smoother. Your feet on the floor board will thank you for the smooth and stout upgrade. The prop will compliment the 351W / 240 HP engine very well.

The Perfectpass is a must for any enthusiast boater. For your skiing, you'll love it, and more so your driver will really like it.

Two of the top recommended upgrades in my opinion, lest you forget heated seats :D . Easy to retrofit on most any model and your wife will love you more while she is driving on cool days.

I just added perfect pass and a Bimini to my 89 Prostar. In my opinion money well spent. Good luck with your upgrades!

Acme 543 for me. (11.5" pitch)

I have no reason to dislike OJ. When I was prop-shopping a couple of years ago, the few test results I could find indicated that the Acme was the better all around wheel, results were very close.

I agree wholeheartedly that a CNC prop will be a noticeable improvement, no matter whether it's OJ or Acme.

FWIW, my '92 carbureted 205 out-performs my buddy's '94 205 with EFI. Just sayin'....
