My main question for now is how best to get the toon off the trailer and onto some supports in order to cleanshine up the toons.

Lift pontoon off trailer. I would do this every time I fly the plane instead of leaving in the water as my lake gets pretty green. I have a boat landing on my property and the plane could be set on the grass and tied down easily. The LL-224 is 31 overall length with a 247 bed length and is 44 wide.

We pair the 1800 lbs winch with a 14 to 1 mechanical advantage. The shop who is experienced at this sort of thingI hope says they will lifthoist my boat off of the trailer to paint the bottom half of the tubes. Put a 6x6 under the pontoons and block it past the wheels then go to the back and lift it up and pull the trailer out.

Lifting on the two cross members on the floats. Then lower the jack and use wooden plates under the jack to give you additional height. Having the pontoons painted with anti-fouling paint TRILUX 33.

Using the two hoist package GoHoist uses lifting chains in place or standard lifting straps. Tilt the trailer tongue down to the ground block up the stern jack up the tongue as high as you can get it and slide a 10 4x4 under the bow block that up on the outside and pull the trailer out. With a Portable Boat Lift and by following the steps below specific to using the Portable Boat Lift you can finally work on your boat or trailer when where and how you want with total access to the hull or trailer.

When the jack extends as high as possible you may have to place blocks and wooden plates under the front cross member to support the boat. Place a hydraulic bottle jack under the tongue of the trailer and raise the front of the trailer. Still reading other threads regarding best methods of cleaning toons but would appreciate any comments from those that have done this themselves.

If anyone has a picture it would be wonderful to see. 1974 Harris 70 HP 4 stroke EFI Yamaha. A strong 1800 lbs self braking winch with a rear stern lifting system.
