Just wondering what winter projects people are doing?

On my 2003 Mastercraft X2, so far i have on the trailer:
- Replaced all the bearing and seals in the trailer hubs (tandem axle bloody expensive)
- Overhauled the surge brake coupler, stainless sleeved the bore
- Removed some surface rust painted with CRC zinc it and finished with hammerite (almost a color match)
- Cut and polish, mainly for rust prevention
- Installing a new Fulton XLT 1800# winch, last one died and was only rated for 1400#
- Rewired the trailer
- Replaced the only roller on the trailer which was broken with a stoltz non marking one
- Cut and polished the guards

The boat:
- Cut and polished the entire boat, used Farcela 300 cut and the UV wax, looks great, no water spots or oxidation
- Installed second battery, due to running 4 ballast pumps at once drawing more than approx 70amps. My engine was fitted with a 70amp alternator thatís provides 25amp at idle and 70amps at 2500rpm. With this in mind i added a 1200CCA battery giving me at total of 1860CCA. I installed new 35mm2 cable to the starter motor (i donít like joining cables in boats), and 35mm cable for the batteries. I used 2 BEP single battery isolators (i already had one installed) for switching.
- Replaced the 40amp circuit breaker to the house electrical system with a 150amp unit. Again this was tripping when running the stereo and only two ballast pumps.
- Installed a second amp for the tower speakers

Yet to be finished:
- Replacing the tower speakers with infinity components. Next time i will just buy Adams X-air tower speakers in the pods.
- Finish the addition of the fourth jabsco ballast pump. Last season i just used alligator clips.

I've been working on a trim tab system that integrates into Perfect pass. The idea is it puts the tab full down for plane up and moves the tab up automatically once at riding speed. It should reduce the running cost when fully loaded up, allow me to tune the wake to be less intimating for when the women and children are riding (Cam) and lengthen the pocket when surfing.

Should get the final install done this week.

I'm interested to know more about how the trim tab controller integrates with PP. What signals is it using ?

It uses the pulsed output from the paddle wheel. There is an adjustable trim pot on the control box to set the speed at which the tab moves from "plane" to "ride" position. The 0-100 knob in the middle of the face plate sets the ride position so you can go to the same place every time the boat starts. There is a trim pot on the box to set the plane position so it doesn't necessarily have to be full down. You can also turn off the auto adjust function and just use the up down buttons to set the plate anywhere.

A plate system on the X2 would be awesome, it would knock all of the bow rise on the head for sure. The Sanger doesn't have a bow rise issue, my application is more to mellow the wake out for the family.

Hmmm makes my winter projects seem boring. Would the trim tab work kind of like the Nautique plate that i have seen on the transom. I see it is actuated via a slide lever by the driver.

On the x2 it would sort out the porpose issue when you dont have the ballast weight quite right(we seem to have it dialed now) with no more porpose at wakeboard speed.

I dont think the bow rise is such an issue in mine as we are adding +200kg lead in the front and the ibs intergrated bow sac full.

Definitally it think this boat uses more fuel than my last mastercraft 205 DD. I have the 350hp MCX engine running a short prop and had an issue with the thermostat which has just been fixed which i think made the engine run rich, will soon see. So any fuel saving device like the trim tab would be a good thing. It would be very interesting to see what if any fuel saving there would be vs the cost of installation.

When you own a boat for 6 years and put 700hrs on it your projects start to get exotic to the point of being bizarre. I need to get a new boat ASAP because this one is looking like Xzibit play thing.

Similar in application to the Nautique Hydrogate but different mechanically, this is a classic plate system like as used by Supra or Tige'

I put a tab on my old woody after we had the strut area rebuilt (post boat vs log, log won).

I was amazed, the tab did practically nothing except adjust the prop wash! I never did figure out how the Tige and others got so much effect from them...

Got tab and control installed yesterday. Needs some tweaking to get the auto function working but works great in manual. Encouraged how the tab affects boat performance.
