1972 20 SF weight?
 

I checked the specs page but it won't load for me so... Anyone with a 20 SF know what their boat weighs with 50 gal fuel tank plus 200 lbs of ice and Yamaha 115 2 stroke? Having trailer tire issues. Thanks

If I remember correctly dry weight is 1600lb.

That's just the hull I assume?

Yes, 1600 lbs is dry weight. No motor. You're probably at least 2500 lbs with that load. Maybe closer to 3K.

Don't forget the weight of the empty trailer when you are adding it all up

Do you have tire issues or axle issues. Single axle or dual, conventional or torsion. A long time ago, I switched from a 17' Mako to 18' SeaCraft on a single axle torsion type trailer. The Mako was probably close to being overweight for the trailer and apparently when I switched to the sc I tweaked the axle on my little trailer, causing blow-outs.

Well are you running a single axle. I went with a duel axle and its a world of differance

Tires are the symptom, axle is the cause I believe. It's a single axle torsion venture roller trailer. Both tires are wearing heaving on the inside.

Chance I think a 5000lb axle could be in your future. Look's like your right on the money, it appears there's some flexing going on back there. Do you have a 2'' 3500lb axle ? 1600lb boat 400lb motor 400lb's of gas, 1000lb's of trailer or so; plus gear. I always think about those bumps in the road and the flexing going on back there.

Good Luck Bill

If you are not overweight, there is another way to cause the bent axle. if your submerging the trailer to launch. I found out firsthand when the wheels went past the end of the concrete ramp and kind of got hung up on the way up. It caused a toe outward condition and I had to replace the axle.
