I bought my boat and trailer used last year from the original owner. I have a 1991 Regal Valanti 220XL 22' bowrider (dry weight 3700 lb) and a 1988 EZ-Loader T22 tandem axle roller trailer (32 rollers).<br /><br />My problem is this: although most of the rollers appear to be in OK shape (worn but not falling apart), loading and unloading the boat seems to be more difficult than folks on here make it out to be. To launch, I have to submerge the trailer very far (completely over fenders, almost to tongue jack, to where the boat can pretty much float off. Otherwise, try as I might, I cannot push the boat off. To retrieve, I back in just as deep, and winch it on. The last 4 feet or so are very hard to crank in - to the point I worry about pulling out the bow eye. It's almost as if the rollers are not rolling. I cannot back the trailer in deeper or I will be be submerging my truck's rear axle.<br /><br />With the boat launched, I inspeacted the rollers and they are not stuck (they turn with no load on them. But loaded I noticed that the weight seems to ride on the metal washers instead of the hub of the roller. Is that correct?<br /><br />I was going to replace all the rollers with the yellow poly ones - do you think that will help, and are there any special tools or information I should have before beginning that project?<br /><br />Thanks for any help you can offer!
