I am a new owner of an 1988 2001 Ski Nautique and the prop has some dings in it. Are these serious and will they cause transmission issues or motor vibration issues? What are my options can this be repaired or do I have to replace?

Welcome Troy. Others with more experence with your year and model will reply but here is your chance to just use that money for the repair toward a better new more modern prop. Delta prop is a site sponser and has a discount for us. Their add is in the left side column. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

My Grandpa has a 1989 SN 2001. For his birthday several years ago we bought him a new 4 bladed OJ prop. I like the OJ opposed to Acme, but either way, getting a 4 blade over a 3 will totally increase the pull out of the water. Made a huge difference on his, But I would buy a new prop, because not only are you fixing the issues the old one will cause, you are upgrading as well. ------------- 74SkiNautique |

Do some research before you buy,4 blades are old technology, look at a Acme 540 ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

+1 I put the 540 on my 82 this winter and love it! ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

+2 on the ACME 540 unless you're using it mainly for wakeboarding purposes then you should go with the 542. Less top end with the 542 but better hole shot when loaded down with ballast and peeps. ------------- "Morfoot; He can ski.

Tim, what do you get for WOT RPM's on your '88 with the 540? The more time I spend in the late 2001's (87-88), the more I think they need less prop. 542 may be the way to go for all around use. I wish I had one to try on the '87 thats currently at the dock... but I'll bolt up a 540 and get another data point. ------------- |

Buy a new prop. Have that old one repaired and keep as a spare. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=2798 - 93 Sport Nautique |

| Yeah I called Delta props and they recommended the 542 which I am ordering right now. |

Here's the thread I tossed up a few years ago just after I installed the prop. WOW! Holy cow what a difference the 540 made on the boat. It's just as everyone has described here as the hole shot was incredible. The bow came up about half as much as it did with the Federal 13x13 and it was allot smoother. The boat seemed to handle more solidly and with just me and a 100lbs of weight on the observer side to balance it out she seemed to turn more solidly with less cavitation of the prop in high speed quick turns. I did (as expected) lose a little top end but it's rare that I throw the hammer down and run full throttle so that doesn't bother me. I did forget my notepad in the truck but took some snaps with my phone and recorded a few readings. It was money well spent and I too am looking forward to the first chance I have to ski and wakeboard behind her. Merry Christmas to me! This is on a stock 350 with pointless ignition with 890 hrs on her using a GPS for velocity. Weather conditons weren't ideal with a little breeze blowing. The water wasn't glass but if I were skiing I would have been all over it. 2200 - 22.2mph 2400 - 25.4mph 2650 - 28.3mph 3200 - 34.8mph 3550 - 38.1mph 3800 - 40.3mph 4600 - 43.5mph ------------- "Morfoot; He can ski.

I assume you meant stock 351w  4600 is perfect, so the 540 is ideal for you. I have not seen another 2001 that can turn a 540 beyond 4400, so that is some strong performance. The other boats Ive tried the 540 on were the earlier version and ran between 45 and 46 at 4400 on the nose. I seem to remember our '88 running about 42, but that was a long time ago and who knows how accurate that was. The '87 I have right now needs a tune up, so we'll see if I can get it to run better than the 4000rpm and 39mph its currently good for (with a dinged up Federal, presumably a 13x13). As far as your note on the conditions go, a little bit of chop is generally ideal for top end speed- just FYI! ------------- |

Ooop.. ..... Yes Stock 351w The data was taken 2.5 years ago so maybe I should do this again just for giggles to see if there has been any change after 100+ more hours have been put on the engine. A little chop is ideal for top end speed but didn't know that at the time I wrote the original post. Oh the things you learn from hanging round guys with fast boats.  ------------- "Morfoot; He can ski.
