Author Topic:   Lifting Outboard w/ engine hoist

John O posted 03-16-2003 12:55 AM ET (US)
I rented a engine puller to hoist my old 1988 Johnson 88hp off my Newtauk and onto a wood rack that I made. I want to mount my new Merc 75hp onto the transom and bolt on to deliver to the marina that is adding all the controls, cables etc.
I was considering bolting a piece of 2x10 onto the Merc and lifting with a chain. I do not have the fitting that screws into the Merc. Power head. With three men to steady the motor I think it would go smooth.
The hoist is a commercial grade used to pull automotive engines. It's heaght is approx.65" and uses a hydrolic piston. It also has wheels. Cost $30.00 to rent from Sat-Mon.
Any feed back?

I found this on another forum. I have no idea about its validity:
"You can use a standard puller found at your local tool store. I just changed motors on my boat and used a puller purchased locally. Measure the spread on the holes in your flywheel so you know what size puller you need. I got an extra center bolt (purchased at an industrial supply store) and welded a picking eye to that so I didn't have to mess with the cener bolt that came with the puller. I also ground the end of the center bolt to a bevel so it would mate up with the dimple in the end of the crank at the flywheel. You simply bolt the puller to the 3 holes in the top of your flywheel, (I had to buy additional bolts to match threads with the flywheel)screw in the center bolt with a picking eye and your set. I have $20 in the whole contraption and am left with a puller I can use for more normal projects."

John, the Merc tool costs about $30.00. You could then resale it for at least $15.00. The wood sounds precarious. Get the right tool for the job. Or: If you must, use a safety rope (1/2in. doublebraid) on the hoist and between the braket and exhaust housing. Just in case something gives. Steve

Good reference. Now I am a bit confussed. The loop on the Johnson power head can or can not be used to lift the engine? I was going to use it to remove from the boat. I do not have the Mercury part that screws into the power head and planned on bolting a piece of 2 x 10 to the motor where it would normally mount to the transom and then steady with three guys and remove wood and mount to boat.

You are right Steve. I may have a problem locating the Merc part on a Sunday. Does that part simple screw into the power head?

Hi John,
Last week re removed a 70 from my father's boat with the hook on top of the OMC powerrhead. This hook is placed there for the doing this and works very well.... It is a shame that Mercury has not done this.

thanks guys,
We finally have some good weather here in the Northeast.
Well I am off to find an open Mercury supplier.

You can use the hook on the Johnson / Evinrude product. You need to use the loop on the Mercury product. If you absolutely have to do it today get some welded link chain. About 2ft of it should suffice. Remove (3) three of the bolts on the inner flywheel. These are fine threaded case hardened bolts. The trouble is that they are too short to go through the chain links. Go to a good bolt supply store and purchase 3 bolts twice the length of the ones you removed. Make certain that they are the same thread size (bring one with you). Also buy some thick washers for these bolts. Now: Thread the bolts through the chain into the flywheel, making sure you have a loop for the hoist to grab onto. Good Luck, Steve

Oh, I forgot to add that you will need to space the three bolts you remove. Try and make them equally apart from each other. Email me if you have any questions. Steve

John,
Here is the url to Harbor Freight, they have a 440#/880# electric hoist for $75. This seems like a very good price, depending on the quality of the unit. It may or may not be of help to you, but I thought I'd mention it just in case.

Got the job done today. Went by the marina that I am keeping boat at this summer and found one of the owners working on his truck. He lent me the proper ring hook. The motor puller was a must. I got a little scared when my buddy wanted to remove screws that I believe are used on the manifold block. He still insists that we could have rigged the hook from the Johnson onto the Merc with theses. Made some claim that they were rated for 4000 lbs. I said "no way" and was able to get the lifting eye. We did have one mishap when he rigged a chain to the pallet to pull out of garage. He wrapped chain around the center board of the pallet rather that around the exterior boards. The pallet I assume is standard with 3 boards running the lenght of the motor. At any rate the motor twisted an fell on the starboard bottom cowl.
Suffered some nice dings and 3 nice cracks in the cowling. I am pretty sur the daamge is all cosmetic. I will have reglassed or replaced. Am I being optimistic? I aasume the bottom cowl which comes in two seperate pieces offers no mechanical support other than keeping the motor dry.
The Johnson came off fine and we bolted the Merc on the existing holes. I will trailor the boat Tuesday to have it completely installe by the marina which is merc cerified, but does not sell motors. Every thing is stripped off the center console and I removed the RPS to give the mechanic more room to move around. Currently the bolts are on the 3rd hole from top. It looks like it will need to be on the top hole. I will research in the archives for that answer.
I recconmend the motor puller. Two guys can handle it well. Be sure to use a flat surface and if you use chains to drag the pallet out of the garage wrap them around the widest part fo the pallet even though my buddy claims it adds no more stability.

I am a bit tired and stressed after the afternoons "mishap" as evident from the several typos in the previous post. Sorry Gents.
