I need to replace the bunks on my trailer and would like to paint it while the boat is off. I've been kicking around the idea of using two cherry pickers to lift the boat off the trailer. My plan was to use one to lift the bow up with a strap through the hook and another attached to the engine to lift the back end. My question is: Is it okay to lift the back end of the boat like this?
Thanks in advance,
James

I have taken two boats off trailers along with my uncle and buddy, we use 4x4's and 2x4's to brace the back of the boat jack up the front of the boat and slowly work trailer out and brace the middle and front as you take the trailer further and further out from under the boat. We actually still have one boat to put back on but a buddy is lagging ass on lights and bunks, he had one day paint and body paint his for 3 bills.

Another option that is a little less scary than lifting a complete boat would be to try and find an empty boat trailer to borrow, or if you have a flatbed trailer like a car hauler you could build bunks or anchor some old tires to the deck and take them both to water and swap the boat over. It’s a little hillbilly but it does work

That would be ideal, Unfortunately no one I know has an extra trailer laying around. I still haven’t gotten around to fixing this yet. I have been thinking though... would it be possible to jack one side of the trailer up, support that side of the boat, then let the trailer down and replace the bunks one side at a time? Where would I put the jack stands and wood blocks?

I have seen my dad replace the bunks on his trailer this way, he didn’t jack up the whole trailer, just used a couple of bottle jacks and some 2’’ x 6’’ a few feet long and jacked the boat itself up on its side a little just enough to slide out the old bunks one side at a time. If that makes any sense.

I think this is what I'm going to do (Unless someone here has a trailer I can borrow for a day ;D) I feel more confidant this way rather than lifting the whole boat off or leaving it supported by stands all day. Where did you dad place the jacks and wood before lifting the side of the boat up?

It’s going to depend on where you have access to jack it up from. His was rather easy, he was able to put the 2x6 pieces next to the bunks (more towards the outside between the strakes) and place the jack under them and support it just like the bunks were on the trailer. Try and lift up where the stringers are or next to the side of the hull. Make sure you use some solid pieces of wood and decent size that will even out the load from the jacks. Try and get one near the transom and the other one about the middle (three would be better). You might have to play with where you lift it from. You just want it to be even, don’t try to lift it from one spot. You’re not trying to jack it up all the way, you just want to roll the boat on its side. I hope this helps…

Thanks for the tips, I'm gonna check it out this monday and see what I can rig up. If possible, that's probably how i'm going to do it.
Just to be sure you’re talking about placing a "bunk sized" piece of wood where the red arrows are and jacking it up just enough to clear the bunks on whichever side I’m working on correct?

drop the tongue, the ass end will come up, put jackstands under the hull a little bit forward. lift the tongue the trailer will drop, the hull will stay put. support the front. pull trailer out until it hits the jacks, put jacks behind trailer and then pull the front ones out... if you take a 2x4 and chop it into 1x1' blocks and make little stands out of em stacked up...

Replaced my boards the bottle jack method last month. Lifted one side, remove, measure n cut new boards, countersink bolts, cover boards, reinstall, lowered boat and repeat on other side. Took one full afternoon by myself.

That method sounds like the best for my situation. If anyone has pics that would be great (im a visual learner)
@5150whiteboy - my brotherinlaw is going to help me out lifting one side at a time, if that doesn't work out i will take you up on your offer of removing the boat off the trailer completely.
Thanks again for the tips and offers, i will be attempting next weekend and will hopefull be successful.

Get 4 8' 4x4s, 2 10' 4x4s, a few 2x4s for cross bracing and to make legs for your "cranes"....and build 2 gantrys.. Use straps to fasten the bow and stern to your gantrys, let the air out of your trailer tires, then drag the trailer out.

or you can do it like this >:D[attachimg=1][attachimg=2]

Well i decided to just replace the bunks at my local lake, the painting will have to wait. I had some bunks made and will hopefully get these installed on Monday. I figure me and a buddy can have the old ones off and new ones on in 20min. Thanks for all the tips and offers to help but to be honest I just dont feel safe, Murphy loves to visit my house.

Well I got them on. Took me a bit longer because my buddy bailed on me :mad: I messed up on one and it sits about a 1/4" back further than the others but hardly noticeable. I was a little shocked when my dad said that was the original wood, 34 years old! I took it to Puddingstone hoping to get some time on the water afterwards but odd days are PWC only in the speed zone, max for boats was 12mph. That and a water inj header problem made today a maintenance only day :'(
