Greetings, all-I was just putting the new year-registration sticker on the 170 yesterday and, since I was dealing in dates, realized she's coming up to her 6th birthday-- her being a '99 model. I don't think the guy who sold me my 170 (he was original owner) did anything toward servicing the bearings. Does anyone know how often/ and HOW bearings should be serviced on this size trailer? It's called a "MagicTilt". On my trailer-sail a couple weeks ago I thought, "Hmmmm, I hope the bearings get us home!" This is something I probably should have already attended to, but no time like the present...Also, has anyone replaced their 170's main halyard lately and if so, can you recommend a good line for this task? I just replaced my boat's original topping lift which was about shot, and the halyard's next on the list.Best,Gball
