Much depends on the angle of the ramp. I use only ramps with docks for this exact reason. My buddy blew the motor up on his dirtbike. A shallow trailer will do WAY less damage than a trailer in too deep and like everyone has said, slow on and let it settle before powering on. Start with a good line up to the trailer, then in and out of forward gear as you ease toward the trailer--I usually am in gear only seconds at a time then back to neutral. The fluid is then returned over a meter out circuit across a valve, back over an oil cooler and into the tank to flow back up through the pump, etc.
Of course as mentioned above, give yourself plenty of distance to be able to drive the boat straight onto the trailer. To deep on a river especial is not good. I believe you are correct in saying that the linear acceleration should have little effect on a spinning wheel regardless of orientation. At this point my speed is almost zero and I am also lined up. Basically you want the bunks to guide you on or off. Lots of people use the fenders as the guide to depth, and to an extent it works, but I like to use my front set of bunks.

Yinzer Moto , Dec 4, Mar 21, Oddometer: Are you talking inner or outer bunks? Thread Tools Show Printable Version. Sure as shoot, the shaft runs in a bushing a bearing can't seal the pressure and the rotational maximum speed is predicated on the ability to lubricate this bushing. As somebody who has a winch on a truck, get a good couple of pulleys and rope instead.
In extreme cases, the connecting rods between the crankshaft and the pistons could bend and snap with an alarming force, which could send one or more of them out through the side of the engine block. Eventually the line will become tight, the system pressure will rise and a tug of war will ensue between the pilot and the rewind motor. Simply mounting a spool sideways doesn't necessarily mean that a hydro motor will seize up. The Basics for me are: If I were you, I would hand winch up a couple of times and see what the heck the boat is doing, sounds like you have a very steep ramp.
