TNT Woes

[saltshaker]

One side of my TNT tender lift dropped down this week. Port side fell about 8" lower than the starboard. I was able to get it back up but it is leaking fluid most likely from the cylinder. Any thoughts about replacing this in the water or do I have to haul the boat? Getting the boat hauled now would be tricky as any of the yards that can haul me are already booked up for the winter so if have to do it in the spring. Hate to haul the boat if I can do this in the water as hauling my boat is a bit of a pain due to the distance and availability of yards with a big enough lift. Most here are 50 tons which isn't going to work for me.

Are the cylinders accessible with the boat in the water?

What size are they?

I would need to dive to do the work. Cylinders are pretty big. Two lines to each cylinder but should be straight forward to replace with dive gear. Just don't want to get water in the system but if I did it's pretty simple to flush and refill.

Same thing happened to a boat in my marina late last summer and they decided to haul it for those reasons. I saw what they did and would think it would be pretty difficult to do in the water. Now that I think about it I believe it ended up being a line that they had to replace. Two guys were up in between the lift and brackets and were wrangling with trying to get the lines off.

Can you make a cofferdam?

Are the lines long enough to to disconnect the cylinder and then change the fittings above the water?

Pressurize the lines with air while hooking them up to keep water out. Lots of redneck engineering ways to get'r'done.

This is what I was thinking. The lines connect just above the water line and at the cylinder below the water line. Out of the water would be the easiest way to work on it but hauling this beast is a project. Last haul out was too close for comfort as the boat barely fit in the well. The lift was 55 ton and the boat weighed in at 54 ton with next to no fuel and no water.

You could always run her a ground at dead low tide. Then do the repairs and back her off when the tide comes in. Just don't forget your extra wheels, you might need to change those also. I figure 23 to 25 knots should do. Anything slower not you might not beech it enough and all your troubles will be for nothing.

Get 50 of your best friends to stand on the bow so the stern comes up enough to access the cylinder.

My solution is a hacksaw and get rid of it !

Now Dave I love TNT lifts. I have an old set of cylinders in the back of my truck that I changed out. Nice scrap and I love the $2,000 parts cost. Made money on the project an probably will again in about 2 years.


I Love TNT lifts.

FYI Jack are you using it regularly? It probably needs to be run to keep everything lubed and protected.

I was waiting for you to chime in and this is exactly what I thought you'd say. Kids love to swim and now they have all the water toys to drag out with us.

The parts are ridiculous. I'd never put one on a boat and I have thought about taking it off. I agree the problem is we don't use it enough. I had it fixed when I bought it and the PO had it fixed at least twice. It was only 2 years old when I bought the boat so it's definitely not reliable. That's why I don't use it much. I'm always concerned it will crap out and ruin my season. It's been over 5 years since the last fix and this time I think I'll just put a new cylinder in and use it more often. My neighbor just cut his off of a 62 Ocean and tossed it in the dumpster. Wish I got it before he trashed it all.

Well some people might mistake the 65 for a Sea Ray when they see the TNT. Just trying to help.....

Damn, good burn! But hey, that's what friends are for.
