Lifting boat off trailer by hull engine mount stringers
« on: April 11, 2020, 12:59:22 PM »
Hi:
Are the engine attachment points to the hull strong enough to lift the boat hull off a trailer?

I have a 21ft 76 Tahiti Boss Cruiser jet with a 460 and Hardin engine mounts and hardware. I want to change out the side and bottom bunks of my trailer by just lifting the boat off the trailer about 1 inch and changing out the bunks one at a time. So I was thinking of using my engine hoist by lifting the engine (which is still attached to the boat by motor mounts) to lift the whole engine and stern of the boat and pivoting on the bow roller of the trailer. I have enough lifting power to lift the engine/hull combo (720+1600=2320Lbs), but I am concerned that the two engine mount stringers and attachment points are not strong enough to support the dry weight of the hull (1600Lbs). My stringers are OEM design and the engine mounts are Hardin aluminum mounts with 2 bolts each through the stringers.

Does anybody have any knowledge about trying to do this?

Regards,
Henry2

I have used a jack to lift the rear of the boat from the jet, and an A frame hoist to lift the bow using a strap going through the bow eye. Mine is also a 21 ft cruiser.

I once tried to NOT have a good time. It just didn't work out!
