bigtallweed Posted September 21, 2013 Share Posted September 21, 2013 I have a 1994 Malibu Euro f3 and was wondering if anyone has had success with upgrading to a newer cnc 3 or 4 blade prop to soften the 15/22 off wake or reduce the rooster tail on this hull? The 28 off wake and shorter are great and 15/22 off are better than the Sportser I also ski behind but not as good as the 98 tsc1. The current prop is the factory 3 blade.

Baller nam1975 Posted September 21, 2013 Baller Share Posted September 21, 2013 I put a new 3 blade on my 99 Response. I don't think the wake needed much help. It did help hole shot. Got rid of the factory 3 blade stainless. 98 nautique is tough to beat. I ski behind one too. Link to comment Share on other sites More sharing options...
bigtallweed Posted September 22, 2013 Author Share Posted September 22, 2013 @nam1975. How does your 15/22 response wake compared to the 98 Nautique ? Link to comment Share on other sites More sharing options...
Baller nam1975 Posted September 22, 2013 Baller Share Posted September 22, 2013 I don't notice either one really. 34 mph for the most part, 32 early in the year or for a warm up. If I had to give the edge, the Nautique is a little better, but some of that is the feel of the pull. I like them both really. Not much difference to me.

BobE Posted September 23, 2013 Share Posted September 23, 2013 I have a great prop for your Malibu. It's a 3 blade Acme that I had Acme take down the diameter to 12.3 from 13 inch diameter to make the wake better at 22 off. Acme also balance the prop so it is super smoothhhhhhhhh. 12.5 x 12 pitch. $300. plus shipping. Call if you are interested. 970-390-7595 Link to comment Share on other sites More sharing options...
Baller_ DW Posted September 24, 2013 Baller_ Share Posted September 24, 2013 I installed a 3 blade Acme on an Echelon and it works very well. The Echelon does not have the roost but it did reduce the bump there & softened it over the CVP stainless prop. What is the unit currently on the boat?

bigtallweed Posted September 24, 2013 Author Share Posted September 24, 2013 @ DW It has the factory bronze 3 blade. It does have a slight bend in one of the blade tips ( boat came that way). The 15/22 wake is not bad and have had compliments from others who have skied behind it but if new prop technology would make a noticeable softer or smaller wake I would change. Would you say your wake improvement was significant or subtle? Link to comment Share on other sites More sharing options...
Baller ForrestGump Posted September 24, 2013 Baller Share Posted September 24, 2013 A tweaked prop can induce a hard wake. Link to comment Share on other sites More sharing options...
Baller_ DW Posted September 26, 2013 Baller_ Share Posted September 26, 2013 Not dramatic but noticeable. Important note, my change was from a stainless prop to a nibral CNC prop so the material change made most of the difference. The hull shape certainly has a major influence on the wake specifics so you might try some minor tweaks on it, such as additional hook and make sure as much stuff is out of the rear as possible (remove rear seat, keep fuel level low, etc.) Link to comment Share on other sites More sharing options...
Baller PurdueSkier Posted September 26, 2013 Baller Share Posted September 26, 2013 @DW can you explain how you would go about adding additional hook to the boat? I have an older Malibu echelon with a pretty hard wake at 15 and 22 off. Gets better at 28 and nothing at 32. Boat drives and tracks great but really hard wake at the longer lines.

bigtallweed Posted September 26, 2013 Author Share Posted September 26, 2013 Y@DW the back seat is never in and I have a max of 6 imperial gallons in the tank. I have heard of a hook being added to a the death star but not any other hull types. As I said the wake very skiable but rather than straighten the prop I would go new if it would improve the long line wake by a very noticeable amount. It seems that not many ballers have had or do have a Malibu Euro f3 or Skier and tried different new props? Link to comment Share on other sites More sharing options...
Baller fu_man Posted September 26, 2013 Baller Share Posted September 26, 2013 I don't understand how a prop can effect the wake that much. Can someone explain? Link to comment Share on other sites More sharing options...
Baller_ DW Posted September 27, 2013 Baller_ Share Posted September 27, 2013 @fu_man: different levels of cavitation or frothing of the water will alter the softness of the wake table. Also a different profile prop blade will change the thrust wake from the prop itself. @btw: those boats were not created in an era of numerous prop options, so probably little data available. Maybe you can find somebody that basically did the promo thing with one of those boats and they would have some tips. Actually, the Malibu SV23 hull has had the hook changed over the years. @btw & PS: an easy way is to take some bondo spreaders and tape them to the hull bottom with shrinkwrap tape. Easy to remove if you don't like it. Other method(s) include bondo or even fiberglass. @PS: did you have a Goode 9700 for sale on SIA? Link to comment Share on other sites More sharing options...
Baller PurdueSkier Posted September 27, 2013 Baller Share Posted September 27, 2013 @DW thanks for the hook tips. I like the idea of being able to test with the shrink wrap tape and not be permanent. That wasn't me on SIA. Never had a Goode. Link to comment Share on other sites More sharing options...
Baller_ DW Posted September 27, 2013 Baller_ Share Posted September 27, 2013 @PS: how serious do you want to be with that boat? I have a similar craft and drastically improved the wake but it does take some effort. Not cheap, but much cheaper than a new boat, swap out many of the cast iron engine parts for aluminum: cylinder heads, exhaust manifolds, intake manifold & if adventurous, swap out the tstat housing for a lighter one. That will get you 250#. Link to comment Share on other sites More sharing options...
Baller PurdueSkier Posted September 27, 2013 Baller Share Posted September 27, 2013 @DW probably have this boat for another few years until the family and budget are ready to upgrade. Part of my issue is The weight. I have the Pres. Edition with The 454 big block. Great HP and EFI but adds weight to the boat. Not sure if replacing parts would be enough to be worth it. If I try the hook do I put it on the center section, outside 2 sections, or all three? Link to comment Share on other sites More sharing options...
