Rybuffett Posted March 2, 2018 Report Share Posted March 2, 2018 My local dock/davit company setup bunks for my lift on a 2500 pathfinder. They welded in a piece on the back to “catch” the step, but it seems too big. The whole setup isn’t right. Anyone else do something different that works well? Sorry the pic is upside down.

SCFD rtrd. Posted March 2, 2018 Report Share Posted March 2, 2018 Wow, I would have that fixed pretty quick. You have a lot of weight resting on two small areas. I'm about to go through the same thing, but will be on hand to supervise the modifications. You might be able to solve the problem by adding some material to the front of the bunks (near the bow). If you add height to the front of the bunks, that will lower the hull at the stern. This modification is something you just can't eyeball or use a scientific guess. Someone actually needs to get in the water and add material, such as 2x4" and wedges to certain areas between the bunks and hull until the correct angles and support is achieved. Then, they need to translate those angles to a piece of permanent material and add that to the bunks. My idea is to remove the plastic material that is attached to the bunks (at the rear of the bunks), then add a marine grade 2 x 4 to the aluminum bunks, then reinstall the plastic material to the 2x4's.

Vapor Trail Posted March 2, 2018 Report Share Posted March 2, 2018 If they got a very accurate measurement of the gap in the back they could move the boat, cut the flat bars on the side of the tubes and lift the back of the shorter tube to the correct height. Then install new flat bars on the sides. Link to comment Share on other sites More sharing options...
Rybuffett Posted March 2, 2018 Author Report Share Posted March 2, 2018 Fortunately the bunks are wide, but yes way too small of a contact patch for all the weight. I have 2x4s now in the back to support the transom. They are building new bunks for me with a smaller step. Hopefully it’ll fix the problem.

SCFD rtrd. Posted March 2, 2018 Report Share Posted March 2, 2018 Good luck, please send some pics of the new bunk arrangement. Link to comment Share on other sites More sharing options...
Rybuffett Posted March 13, 2018 Author Report Share Posted March 13, 2018 Update: new bunks were made with 1 3/4” step welded in, just like the first picture only smalller. Fits much better now. Couldn’t take pictures cause it’s dark but will try and get some soon. Link to comment Share on other sites More sharing options...
