Supra Sunsport Trailer measurement question

[mabbore]

Hey guys, so I picked up this Supra Sunsport skier (1987) and trailer about 4 months ago. I have had her on the chain of lakes a dozen times already this year(w/wetsuit : ). My question is about the trailer seen in this pic (sorry its not better, its all I had that showed the trailer). The trailer is clearly not original, it a roller trailer and the main issue is the axles are not placed accordingly to provide the proper tongue weight. From the pics I have seen on here, it looks like they axles are placed too far back putting too much weight forward of them placing too much weight on the tongue. Also I am a pretty big guy (6'3" 265) and I cannot even remotely budge the tongue when I try to pick it up. I was wondering if any of the sunsport guys could give me a measurement to help me adjust the axle position. if anyone could possibly give me the measurement of the transom to the center of their dual axles?

Thanks in advance, and hope to see some of the other Supras on the chain this year.

Come on you sunsport guys. I know this is a pain in the a$$, but I would really apprecaite the help.

I don't have a measurement since I have a comp, but I would say just move the axles to where they sit basically right under the engine. The next question is can that be done with that trailer? Its hard to tell from the pics

I have never seen any inboard on a roller trailer. Your boat weighs 3k plus equipment and fuel. The tongue weight should be 300-450 lbs. I would be more concerned about the support on your hull. I saw some trailers on Ski it again and here. How does your prop and rudder fit on the roller trailer?
To answer your question my 89 is 81'' from the bottom of the transom and the center of the duel axles.

Michael,

Thank you so much for your help. THats about what I figured for tounge weight 10-15%. There is actually plenty of room for the prop and the rudder since the rollers make it so high. As far as support the Hull has 4 seperate sets of supports with 8 wheels on each.

Do you have a welder ? C channel ? Why not move the boat back and make a true inboard prop gaurd and bow support , maybe
Take a day to fab up and a day to paint .. Alot easier to do rather than moving axles he'll u wouldn't even have to remove the
Boat

I do have an arc and mig welder and have just been putting this off until I could put my boat on the lift in the water. I really want to weld up a nice inboard style bow stop, add actual bunks and weld up a prop guard. The axels are actually really easy to move, they are just u bolted to the c-channel. This trailer need tires, bearings, and a new master too : (. Whatever I really don't tow much so it can wait.

Rather than spending the whole summer fabing the roller trailer why not buy a trailer specifically designed for these boats. In the long run you will be much happier and spend more time on the water. $ for $ I don't see much diference in cost in the long run. Sure they might be harder to find but with all the stringer rotten corpses out there you will find something in the budget.

[mabbore]

Thats true, but for the budget that I am on, plus this trailer is really beefy.

a sunsport is just a closed bow comp, right?

Either way, here's what mine looks like on the factory trailer:



the angles are different, but your front axle doesn't look a ton further back than my axle... I can roll mine around the dirt driveway with some help, but I can't lift the tongue alone.

If my boat was that high, I'd have to park the truck in the lake to get it off the bunks. Most of the ramps near me are pretty gently sloped.
