Hello all, I am new to this so, please bear with me.

We have had an 85 Skier for about ten years, and I have a question. The Pylon on our boat flexes when a skier crosses the wake. Is this normal? I can't remember this always happening, but I do remember trying to tighten the U-bolts underneath. (they were very tight already) I have skied behind lots of Mastercrafts and some flexed and some didn't. Is ours worn out, and can I get a new one?

Thanks for your time.
Mike

We don't spend too much time on the beach, in MT, your beer freezes 8 months of the year!

take up the floor board around the pylon.check the bolts that secure the crossmember to the stringers.if these are stripped or loose they can be tapped out to the next size.

I had to tighten my u-bolts on my pylon a couple of years ago. Much more of a noticeable flex with the extended wakeboard pylon. It scared the crap out of me at first, thought I was going to rip a hole in the bottom of the boat. They didnít seem to want to tighten, but finally did after I coaxed it with some elbow grease and used my spinach (PBR). Pylon will never wear out, just bend or break (very doubtful that this is possible under practical terms).

Or..... if your boat has wooden stringers, come completely out of the boat. The reason why I don't own an 84 supra Comp anymore is because each time I cut, the pilon moved about 2-3 inches. 2 owners after me, it came out. Along with the rudder a couple of weeks after that. :eek3:

Jimmer, my brother in law has a 99 Supra comp and has a lot of pylon flex. They weren't still using wood in the stringers in 99 were they?

No - I believe they fixed the wood bit in the mid to late 80's. A buddy of mine has a 98 legacy (they're version of the 205) and another of mine has a 99 (also the legacy) and another with a 98 comp. all of their's move about 1/2 an inch or so as well as vibrate. Supra uses a cup & set-screw design on their pilons. The vibration comes from the set-screws digging away at the pilon (the screws don't back out, the pilon loses metal:eek: ) Anyway - I think it's a poor design. One of my bud's who has a 98 Comp asked for a warranty on the pilon... they said "we'll replace it, but the new one will do the same thing anyway".....

Design flaw. go figure.

So are you saying that if it moves, he can tighten it, but then, it'll vibrate?

The ones I know - yes. They were fine for a bit, but after a while, they started vibrating/wobbleing. The pilon seems to be strong enough - but their mounting system stinks.

In both my old 94 PS 190 and my current 96 190 the pylons flex. They are tight and still flex.When I'm the spotter I like to put a foot on it to see how much it moves.Some skier came move it allot more then other.If the mounts are tight and still flexes it is normal. :D

I rode along on a 91 Ski Nautique and it flexed with hard course skiing. The driver/owner said this was normal. The pylon in my 93 p/s 205 doesn't flex at all with the same skier that will pull that supra pylon all over the place. I think his supra could stand some tightening.

My 1993 190 flexes and as far as I can recall, so did any pylon that I have been around. Obviously, my 7 year old doesn't bend it, but when I am out with the boys we all flex it.. (in my MC, in buddies Tige, and other pal's Nautique)

Our pylon had alot of flex when we first got it even though the u bolts were tight. The previous owner did not tighten his wakeboard pylon enough and cracked out the base of the pylon. we had to refiberglass the mount. Just tightening the U bolts may not be enough. Make shure you check the base for cracks and wear. (especially if you use a pylon extension) Once we rebuilt the base the pylon didnt budge even when the big guys were behind it. I am shure that was the problem because i didnt tighten the wakeboard pole enough and cracked out the base again. Needless to say my dad wasnt to happy. Once tightend up again the pylon was great. I hope this helped out :)
