Depending on how much open water is created by your water circulator, and the approach location on the lake, there's definately a few snow-mobilers out there who go for the extra rush of skimming an open water, of say 100', in the ice. They gun the engine as they approach the open water, and lean back a little to make a better angle for the ribbed rubber traction belt to grab the water......and it's five seconds skimming the 34-degree water to cheat a possible icy drowning..... what a roaring noisy watery rush!
About twelve years ago, after trying to hire three guys on a weekend to remove my boatlift I got weary of all the hassle. After one of the prior year's 20-something helpers wound up engine exhaust-rubber hose to talepipe-asphixiated in a car, in a residential garage, in Florida, in a supposed suicide, which some presumed to be a drug related murder and not a suicide; I decided to approach my boat lift removal by myself, with no assistance. So, who wants hired help like that? Sometimes, you are just better off doing things by yourself, without introducing trouble onto your property.
Anyway, what I used to get done with four strong backs, now gets done by one person, myself, using some long planks and a boat trailer winch that gets attached to a tree. If the Egyptians were able to build the pyramids using all hand laborers, then one person can usually figure a way to remove a 400-lb boat lift!
Lots-o-luck! Just work like an Egyptian!
