NEED SOME ADVISE ON HOW TO INSTALL A SWIVL-EZE PRO SKI PYLON MODEL#923-009ADJ IN A 1971 13 SPORT SOURPUSS. NEED TO KNOW THE BEST PLACE TO INSTALL THE 6" ROUND BASE PLATE AND THE BRACE ARMS.

Gilbert,

Don't do it! The 13 is too small a boat for a ski pylon. The smallest whalers that can safely use one is the 17's. If you install a ski pylon in a 13 you very likely will flip the boat. It happened to my uncle and cousin. Boston Whaler itself strongly discourages the use of a ski pylon in these boats and says so in their owners manual.

Gilbert,

You emailed me and said you have a 60 hp Mariner?! Now I am even more convinced you will flip that boat if you mount the pylon. A 13 is not the boat for wakeboarding, at least not with an elevated tow line attachment point. Get yourself a 17 footer and put the 60 hp and pylon on that.

Don't disagree with your warning. BUT, why did the 13' Super Sport Limited of '86-89 come with a Ski pylon built in?

The bigger problem in this case is the 60 HP Mariner.

Thanks.

polaris,

It did? That's news to me, but as my Mother always said: "It's a dull day when you don't learn something new."

I'm sure someone here has a Boston Whaler owner's manual and can quote the section I was refering to.

...sure enough, here's a picture of one: http://continuouswave.com/whaler/cetacea/cetaceaPage19.html

Does anybody have experience with this set up?

HI GUYS:

I SAW THE PICTURE OF THE BOAT AND THIS IS THE TYPE OF PYLON THAT I WANT TO PUT. THE DIFERENCE IS THAT THE ONE FROM SWIVL-EZE CAME WITH TWO BRACES ARMS THAT I WANT TO PUT IN THE FRONT OF THE TRANSOM. I GOT THE BOAT TWO YEARS AGO WITH THIS MOTOR AND I RUN IT TWO TIMES A WEEK AND IS VERY STABLE WITH TWO PERSONS OR MORE AT FULL SPEED. THE MOTOR GOT TWO HYDROFOIL DOEL FINS TO MAKE THE BOAT PLANE FASTER AND STABLE. I USE IT TO KNEEBOARDING AND SKIING TOWING IT TO TRANSOM RINGS.IN THIS TYPE OF TOWING THE ROPE IS TOO LOW AND IS VERY DIFICULT TO DO SOME TRICKS. I WANT TO PUT THE ROPE 8" OVER THE MOTOR CASE.YOU CAN SEE A PICTURE OF SIMILAR BOAT LIKE MINE IN http://continuouswave.com/whaler/reference/13/models.html#sourpuss.PLEASE HELP ME TO DO THIS PROJECT.

THANKS,
GILBERT

Not only is ski rope low, the drag of the
skier is applied well aft, and that makes it
difficult to turn the boat with a skier on.

The ski pylon he is looking at isn't a big
tall onle like the wakeboarders use to get
"big air".

BTW, Gilbert, there's no need to shout (all
caps). We can hear you just fine.

I turned our 13 on its side while slalom skiing using a fixed Y harness on the tow eyes. I changed to a Y harness with a pulley and took care of it. It keeps the load low and transfers it to the proper side of the boat to prevent roll. I wouldn't recommend raising the tow point any higher than the transom eyes.

I too have flipped a 13 (50hp Merc) while pulling a skier. The pulley on the transom bridle had broken so we improvised a Y bridle. I was making a right turn and had no passenger or spotter in the left seat. Forces combined, physics prevailed, and she flipped in the blink of an eye. We swam the boat to the nearby beach, turned it rightside up, and cranked it up on the trailer. Unfortunately, my car keys ended up on the bottom of the lake. When we finally got it home we flushed the powerhead with alcohol and we were skiing again the next day. A pylon seems risky to me.

The section
Tom was referring to in the BW manual says
"Do not install elevated ski hitches on 13' Whalers; they may tip the boat over when a skier pulls outside in a turn. Ski eyes installed on the transom are for ski line attachment. A bridle equipped with a pulley and float is recommended....."
