Rage 14 upgrades

I got a chance to try skiing behind my Rage 14 on Saturday. I can get up ok on a wakeboard, but on my slalom I just couldn't quite get up.
Now I'm no bean pole at 218 pounds but I do have a wide, shaped ski and can get up all day long beind a pwc or regular boat.
The boat needs just a bit more power to get the job done. So, I've ordered a set of Smart Tabs from Nauticus, should be here in time for a trial this coming weekend.
I expect great things from these tabs given what I've read and the difference in the Rage's ride characteristics when I moved weight (wife) to the front of the boat to keep the bow down in the chop.
Pulling the kids on the tube at 18mph (4100rpm) was a constant throttle exercise because that seems to be the speed at which the hull is just on plane and can fall off easily, another characteristic I expect to improve with the tabs.
I'm also considering the performance kit from TurboJet marine ( http://www.turbojetmarineproducts.com/kits.htm ). They have the kit that just includes the nozzle and intake grate mods, not the engine mods. It sells for $450.00 and claims to increase top speed.
I've always been under the impression that modifications done to increase top speed tended to hurt hole shot performance which is really what I need. Does anyone have experience with this performance kit to confirm or discount that it will help hole shot?

You need to inspect the impeller/wear ring for condition and wear.From what you state for preformance(18MPH@4100 RPM)it appears you need some pump work.
The Nauticus tabs are a poor band aid solution to a trim solution.You will find the boat preformance in reverse will be poor, the tabs hang down and make backing the boat up a problem.You may find the passenger moving in the bow from the cooler seat to the bow cushion area a much better solution trim solution to the Nauticus tabs.A proper set of adjustiable tabs is the best solution to trim.

Thanks for the quick reply, tuna1. The numbers i've quoted are when towing the tube. It is a large, two person tube with lots of drag.
I don't recall the rpm's without the tube attached, but I did clock a max speed with just myself in the boat of 34.6mph. Does that number support your statement that I should have the wear ring and impeller inspected or does it seem ok?

The impeller of your jet pump,acts a ducted prop,and the effeciency of the jet is developed and lost at the clearance between the tips of the impeller and the inside diameter of the wear ring-where as the clearance is increased the preasure and volume of water the pump moves drops due to the wear.Anything you do to reduce the clearance to a min. of .020" will be the best money spent on preformance items.

Did you decide to install the smart tabs or go with something else. Elsewhere others have mentioned adding a wedge to an 18 rage but I don't think that may be an option with the 15 rage.

In the end I decided to go with the Smart Tabs. They did not arive in time to install them before the weekend, but I should have them on by the end of this week.
What convinced me was reading the reviews that other small boat owners have written, mostly over at trailerboats.com. By the way, I ordered them directly from the manufacturer and got a price lower than even eBay.
I'm expecting alot from these tabs, I'll let you know what happens as soon as I get them installed.
