Can you use a bottle jack as a jack stand?
The user guide for my low-profile hydraulic jack warns against using it as a stand for static load-bearing duty. Paraphrased, it says that the jack should be used for no longer than necessary and should not be used for extended periods of time.
Can you jack a boat off a trailer?
Jack up the boat and slide the trailer froward until you come to the rear and last crossmember. Place some temporary blocking under the boat as close to the rear crossmember of the trailer as possible. Lower and remove the hydraulic jack. The boat should be sitting on the block and boat stands.
Which is safer scissor jack or bottle jack?
The bottle jack is more durable and resilient compared to its counterpart. The scissors jack has a high tendency of wearing out, especially if subjected to heavy lifts. The bottle jack hydraulic mechanism enables it to withstand heavy pressure from supporting bulky loads.

How do you lift a boat off the trailer to replace bunks?
Lower the trailer tongue as far as possible, which will raise the stern. Place a jackstand (with wood block on top) under each side of the stern, maybe a little inboard of the lifting strakes. Then jack the tongue up, which will lower the stern onto the jackstands/blocks and lift the boat off of both bunks.
How should a boat fit on a trailer?
Set boat on trailer while maintaining no less than 2″ gap between keel and tongue plate cover. The end of the bunks/rollers should be flush with transom and the boweye should reach the winch post. If this is so, the rear pivot should remain in the A-position.
Why are campers so high off the ground?
Older trailers used to have a wheel well so they were lower. About 1/2 of the tire/wheel was above the trailer floor. The newer ones, have the entire floor above the wheel, thus they are higher.
Where does the Jack go on a double axle trailer?
The safest place to jack (IMHO) is under the U-bolt plate, under the spring, just behind the wheel. After all, this is where the weight of the trailer actually transfers to the axles.
