If your on the the throttle while trying to get on the trailer, you will make a ditch where your prop was propelling. so if everyone does this, next time u back your trailer in, your tires might get stuck in that ditch, and that would suck
No problem, it is perfectly OK to drive your boat on to the trailer with the engine as long as there is enough clearance to keep the prop from hitting anything or anyone. I used to do it all the time. As soon as you start to feel resistance from the hull resting on the trailer skids stop and use the winch the rest of the way.
This could damage the engine.
If your boat trailer is situated properly you will need very little effort to get the boat up onto the trailer. Using the engine will result in possible major damage to the boat, the trailer and its towing vehicle. It's always best to use the winch and crank it up slowly as in that manner you are in full control of things, whereas with the motor you are not.
jet drive
The wash from the prop causes a buildup of silt and rocks that piles up behind the motor. Other boats drive over this and it can damage props, or scrape hulls. The silt is washed out from below the ramp, which then causes a hazard for trailers which can back into the washed out hole and get stuck. Many states actually have laws against powering a boat onto a trailer. Read a boating safety course for more information...
If it has an engine and you can drive it, yes. If not (ie you have to tow it) then no, it is a trailer.
Jet drives are used commonly for boats designed for shallow water conditions. Jet boats can have inboard or outboard jet drives.
check your ground wires on the trailer a faulty ground might be a problem
