Indeed, never ending and surpriising how sloppily things are often done or time takes it's toll add in personal preferences and then in 12 months you can do another similar list
I like to detach, clean and tighten every electrical connection when I get a second hand boat, surprising how many loose ones. Usually the trailer lights get completely replaced but only have to do that right once normally.
I spent today rubuilding calipers, using a needle gun and a grinder with a flap wheel to clean the discs up x 4. And a few other associated jobs. Oh what fun, well maybe it was at one time Ramp is only a short distance and looks like we will have to drive a little after wash down just for the brakes.
Unfortunately the 'if you want it done right' saying is mostly on the money
I hope all goes well with the new boat
Cheers
Rod
