Newer (Big) Tracking Fins on an Older VLX

Recommended Posts

trace

Has anyone installed the bigger newer (~'04+) tracking fins on an older ('96 to ~'03) VLX? Gorilla Fins, I think was the marketing name at the time. The typical questions... How much trouble? Where did you get them and how much? Make a big difference in handling?

The biggest issue is that the boat won't fit on your trailer anymore. The newer trailers put the boat higher up to clear the cross bars.

Cant you just put a spacer under the bunks?Or is there something bad about doing that?

skicrave,

Can you think of anyone that's done this mod? I sure can't.

The Gorilla Fins do make a significant difference/improvement in the handling of the boat. As far as what it takes to do the mod, as skicrave said it will be the trailer that would be your biggest problem. I would maybe start by contacting as many people that would know the difference between the 2 & go from there. A good starting point would be the trailer manufacturer & your Malibu dealer. Once you gain enough informtion, it may be something that you can have a local trailer shop take care of. In all reality it may be more cost effective to just upgrade to an '04, but that's hard to say.

Yeah, I don't know of anyone that has made the switch. I also don't know how much of a difference they actually make in handling, as I've never been out in identical boats back to back ('03 VLX vs. '04 VLX for example). I actually think it may be mostly marketing, but that's purely speculation.

If something happened and the tracking fins needed to be replaced anyway I might do the research on this, but purely as an upgrade project, I would probably skip it.

FWIW, I was thinking of doing it on my old 00 LSV and Malibu said they did not recommend it nor would they fit. Dontknow.gif

The difference could easily be the hull change as well - Didn't the VLX hull change in '04?

Thanks for the replies. I hadn't thought of the trailer bunk issue. That would probably amount to more work than just getting the fins on the hull.

The VLX hull changed in 05, and the old hull became the V-ride.

The Vride has the Gorilla fins too. They definitely make a big difference in how the boat handles compared to the early VLX.

No, it was the same hull (along with the Vride as stated) which would indicate that in this case the hull isn't the determining factor. I can see how it may be a problem with the 23' LSV boats, since that hull changed in '04 along with the introduction of the Gorilla Fins, so there would be the chance that they wouldn't fit on that older hull.

I think what Malibu meant was they will not fit in the existing bolt hole pattern. The newer fins have a longer base.

I remember a bunch of talk about upgrading them back in 04 on MBO, but no one went through with it.

I guess I just assumed that this would be the case. I don't look at drilling a few more holes as a big deal when looking at the potential upside of a mod like this.

Could someone post some rough dimensions of their Gorilla fins? Anyone know what they would cost from Malibu, or if they'll even sell them?

Malibu dosen't make them, marine hardware does. Look on their website and you'll find all the specs and drawings.

Cool, I've purchased ballast intakes from them in the past. Good company to deal with (in contrast to my experiences with my local dealer).

Trace, keep us updated on what you find. I may be up for doing this, I've done everything else to my boat so far.....
