Lift Capacity

[wrut]

Hello all. I have a 7200 lb RhinoLift for my G23. The boat is 5900 lbs, the tank has 400 lbs of gas. We have 160 lbs of misc gear, and I have 600 lbs of lead. I am just under the the rating of the lift. I have an issue where over the course of 1-3 days the lift will slowly lower until all the way in the water. I have had the lift checked for leaks multiple times. They are now telling me I need to add an additional tank for $3,000 to increase the lift rating to 9000 lbs. Does that seem right? Seems like the lift must have an issue. I would assume the lift ratings are even on the conservative side.

I posted my this in regards to trailer weights in a different thread (G23 Actual Tow Weights), but it may help you as I came out with an actual boat weight of 6,858 lbs which includes the following.

The boat had a full tank of fuel, 200 lbs lead ballast, empty water ballast, 2 tower speakers, wavefront stereo, battery tender, power tower, and the normal boating supplies spread throughout the boat (1 wakeboard, 2 surf boards, 1 tube, 1 anchor, a few prop tools, 7 life jackets, required safety equipment, and 3 ski ropes).

I estimate my gear loadout was probably 100 lbs or less, but you also appear to have an additional 400 lbs of lead which would likely put you around 7,320 give or take. I can't help with the issue, just an additional total boat weight reference point from an actual scale for a 2020 G23 setup for real world use.

You should weigh your boat and trailer, then just the trailer. That way you can get a true weight. My guess is you are pushing if not over the 7200, wet. Weight adds up quick

It sounds like you are at the very limit of your lift weight wise and maybe a little over the limit. Either way, not an ideal situation.

Having said that, I don't think your lift should sink over time. This defies the laws of physics. If the lift can raise the boat completely out of water it should not sink unless there is a leak allowing water in. The only way I can see a partial sink issue is if the ambient temp drops dramatically after you raise the boat out of the water.

An analogy is an air conditioner...if you have to add coolant to an AC unit then by definition it has a leak.

This was exactly my statement to the lift contractor, and the point of my post. Yes, I may need to add another tank to be safe, but if the boat comes out of the water (even with my whole family on board) 100%, it should stay there unless there is a leak in our current climate conditions.

I also have a Rhino lift and I am also right manufacturer rated capacity, however it lifts the boat no problem with several people onboard and full tank of gas. I have never had an issue with it sinking. I assembled and installed mine and if properly assembled installed it should not sink. Do you know If they put silicone at the hose connections to the tanks? The rep. that sold me mine said he had problems with the connections coming lose and started putting silicone on before attaching the hose and hasn’t had problems since.

If it was me I would invest in a 10,000 lb lift to have a safety margin
