Default Default Jack stands for trailer winterizing

Winterizing a GW 180 on the trailer and want to get the wheels off the ground for the winter. Boat and motor are about 2500's .

Was planning on getting a couple sets of 2 or 3 ton automotive jack stands, they're about $9-12 each, probably cheaper than buying and stacking wood blocks. One under the tongue where it meets the frame and one on each side of the frame by the axle. Anything better I should consider?

thanks,

Rob

I have the same ??? I'm not sure how I feel about my boat sitting on Harbor Freight Jackstands even using 4 of the 3 ton version on boat motor trailer fully loaded at 8,000 pounds.

Who said anything about Harbor Freight? And where did you get 8000# for a GW 180? Hull is 1800, motor is 600, with fluids maybe 3000 tops.

I picked up 'stumps' of cut off 8x8 house pilings from construction dumpsters just for this type of trailer work - I need to replace the brakes on mine.
Jack up the trailer, and put 2 or 3 on their side at the tongue, and 2 or 3 more at each end of the trailer on each side.

We don't have houses built on 8x8' will look around for something similar.
I'll have to go 24" high, 3 jacking points, that's 18 pcs. of 8x8. How long do you make your pieces? Minimum would be 16" for a solid square of 8x8, do you go longer?


thanks,

Rob

Will Pep Boys/NAPA/Car Quest/Auto Zone/Advance Auto/WalMart jackstands make you feel any better?

Why not use Concrete blocks ($ 2,00 with a 2x8 on top of it. Will be more stable then jack stands. Why 24 inches high?

I used to do this with my former boat (an 18 footer of similar wt. to the OP's). Concrete block on ground with a short length of 4x4 on top for the frame to rest on. Then a jack stand under the tongue to take the extra wt. off the tongue jack. Remove the wheels and store them in the boat so you don't have to block it so high.

My frame is 19" off the ground and I'll have to go up more to get the wheels off. 2 courses of 8" block is less than 16". I'll have to use some 2x8 and 4x4.

I use my boat year round, but if I had to winterize, I'd rather spend that time using the boat instead of putting it on and off stands. Sounds like a lot of work for little reward (and potentially dangerous).

Just stick the blocks under the axle right next to where it bolts up to either the spring hanger or bolts to the frame. No need to overthink it. I would just use the tongue jack up front personally, with a block under it if you need more height.

As far as blocks vs jack stands, blocks are far better unless you are specifically on concrete. Jack stands typically don't have all that much surface area touching the ground and can sink in. If you are going to the effort to do all of this may as well take the tires off and get them out of the sun & snow.

My boat with trailer fully loaded is about 8,000.

You have a 8,000lb Grady White 180? Is that in 1/4 lbs?

I just stack a couple short 6x6's stacked under the axle where the leaf springs clamp on to lift the wheels off the ground on my 19cc and dinghy trailer.

You might want to lower that drive so no water sets in the prop shaft cavity and freezes

Waste of time IMO.

Air tires to max PSI, put a mat under the tires, and keep the sun off of them. Store indoors if at all possible.
