Hello everyone, I was logged on before as Lurcher but site problems caused change, I have now had boat in water where I was able to change last roller (rear one) all new rollers, I notice that on my trailer the bunks take most if not all of weight, this is proved by being able to rotate the rollers slightly, I did notice a fair amount of effort winching the boat back on over the bunks, although I was not in deep enough water, I was wondering if I should put a spacer plate under the rollers to bring them into more contact with the keel, the trailer is original one for boat, I just replaced the rollers with original items, in deeper water will boat settle over bunks easier, I do note on other questions here that it is recommended the bunks take most weight, the bunks marked under the hull by me pushing boat off without enough water, should I leave bunks to take weight or pack up rollers, to adjust the bunks at this stage would be a mammoth task as the threads on the inner ones are corroded, (job for winter) thanks again JBD
