From what I see thus far, it would be a great idea to install a V type center roller to help support and install the boat on without hitting the trailer. And it also looks like it needs to slide forward on the trailer so your transom straps are not touching the hull when you strap them down. So you need to determine the weight of the total trailer setup and adjust the tongue to around 10% to 15% of that weight for proper tongue weight. And that could mean sliding the boat forward or whatever it takes to make that weight range. And I can't see for certain but another V type rear roller on the very back of the trailer so the boat won't hit the trailer as it slides on if there isn't one already. And finally, you really need a transom saver or motor toter so the engine is secure and not flopping around while trailer also. When the motor is allowed to move around or up and down while moving, it puts a lot of stress on the transom and a motor toter will stop that... Make sure you service the wheel bearings and seal and check all the lights. If all that checks out good, happy trailering...
