removing the motor?

[tipitina]

Fixing to begin rebuilding my transom with some help from the rot doctor. I was wondering how heavy this engine is? '76 150hp mercury<br />and any easy way to get it off the transom.<br /><br />Thanks

tipitina, <br /><br />According to the NADA Guide, your motor's dry weight is 300#.<br /><br />Tcube

Two things that I've used are <br />1. A motor hoist - I have an automotive hoist with a double action cylinder that works great.<br />2. A tractor with a bucket on front - my 20 HP Kubota tractor will lift 700 or 800 lbs no sweat.<br />Failing either of those maybe a come-along off a tree branch?<br />Hope this helps.

I made a support to lift my motor out of 3 landscape timbers, part of a sheet of 1/2 inch cdx plywood and a $9 cable come-along. The upper corners of the upright were braced with 18" triangles to spread the load. For the base I used plywood triangles 18" high and 60" across. Cheap, efficent, and it worked for me. There was a photo of one some guy posted. That is where I got the design.

Re: removing the motor?

Tipitina I have removed the same motor as you from my speedboat several times. I put the motor under my Garage door header, into which I have screwed a 1/2" lag bolt. I use a cheap block and tackle which I fasten to the lag bolt and to the motor's flywheel. I have used double plumbers strap to attack the block and tackle to the flywheel, by bolting the strap to the flywheel using two of the 5/16 fine thread bolts that hold the outer part of the flywheel to the center.<br />Simply trim the motor down, pull the block and tackle tight, loosen the motor's mounting bolts and jack up the trailer tongue to drop the transom.<br /><br />Alternatively, that motor can be disassembled into upper and lower unit with just a few bolts. This makes it lighter and easier to store as well.

Having a lifting ring that screws into the flywheel will be a BIG help here. I made one for about a buck, although mercury sells them for about $40.

I got a nut at the hardware store the same size as my flywheel nut, and then welded an eye bolt on top of that.
