Grady White falls off of boat lift - Pics
I know... I only post when I have a problem. This happened two weeks ago.
The bolt on the front outer piling holding the boat lift cradle pulley sheared right off and the boat went in the drink. Photos of the boat, the bolts, and some telltale corrosion streaks are stored at the links below. www.thespaceexplorers.com/corrodedbolts3.jpg (boat in water) www.thespaceexplorers.com/corrodedbolts1.jpg (3/4 galv. bolts corroded away to nothing) www.thespaceexplorers.com/corrodedbolts2.jpg (bolt rust stains on pulley housing) OK. So my question is.......... is there any way to diagnose a galvanized bolts integrity before it rusts through like this again? I can't seem to find my portable X-ray machine. I also can't quite figure out how to do a simple swapout on the other three. I don't know anybody who swaps their lift bolts out every few years! Chuck |

Chuck Since apparently no one was injured, the important questions: Was the boat damaged? Will your insurance cover any damages to the boat or the lift? Maybe you need to check the area for stray electrical currents...and also change all the bolts and use nuts and bolts you can swap out every season. |

Chuck I'd be putting stainless steel bolts in there as fast as I could. If you can't unscrew the nut, then a hammer and chisel may be an alternative. Another alternative may be a grinder. |

Which means that you have some kind of current leakage somewhere - maybe from a shore charger? Is your boat isolated from shore side current? |

As a side note: Chuck, no offense but I can understand why you posted the question here and not at your place. ;-) Different chuck, methinks. Anyone, sort of connected, I pull a couple of bolts on my boat trailer every year, just to see how they are doing, and I pull the wheels once a season, mainly to make sure I can get them off if I have a flat, but also to see what is going on behind them, in corrosion. Corrosion can be a real problem on salt water boats, especially. When I installed the deck hardware on my Parker, I first took the hardware down the street from the dealer to a metal working shop, and had the owner cut stainless steel backing plates for me, so that the stainless steel hardware and stainless steel nuts and bolts would be touching only stainless steel, not aluminum. Stainless in contact with aluminum can be a problem. The backing plates were cut from a piece of 3/8" stainless scrap the guy had in the shop. He cut four different plates for me and drilled them for $20 total. |

Yep... its a different Chuck here. Too embarassed to remind everyone what I asked last go-around. Just to clarify, here is a link to a picture of the lift sheave bracket. I like the idea of replacing the old galvanized 3/4" bolts with stainless steel ones. I am trying to figure out how I can do this myself without enlisting a boat lift company who will charge me BIG $$$$ for replacing the bolt on the other side. Have you heard of this happening very much???? http://www.thespaceexplorers.com/gal...rackets001.jpg http://www.thespaceexplorers.com/gal...rackets002.jpg http://www.thespaceexplorers.com/gal...rackets003.jpg |
