DIY lifting Ring for 2017 Mercury 75/90/115 engine cost $2.02

I just raised my 2017 Mercury 115 Pro XS engine a couple of holes on my new Tracker 190TX. Some members wanted to know how I did it and what I used for a lifting ring.
This post explains my DIY lifting ring. I did not want to pay $100s of dollars for a tool that I was only going to use once or twice so I made my own. Very simple when you realize all you need to do is LIFT.

How to make a lifting ring for a 2017 Mercury 75/90/115 hp 4 stroke engine.

The three lifting ring holes on the flywheel of the Mercury 75/90/115 engine are on 4” centers.

The three holes are for metric bolts: 10mm x 1.5 thread
The engine weighs approximately 360 lbs.

Your lifting ring can be made out of almost any sort of scrap steel strong enough to hold approximately 400lbs. It could be a flat plate with 3 holes drilled in a triangle on 4” centers with some sort of lifting ring welded in the center of the triangle.

The metric 10mm 1.5 bolts need to be long enough to fit through the steel on the lifting ring, span the gap between the head of the large bolt holding the flywheel to the crank and thread into the flywheel holes at least 6 turns snugged slightly. The gap between the large flywheel bolt head and the flywheel is approximately ¾”.

My metric bolts were 2.5cm long. They are NOT hardened bolts just regular strength mild steel bolts.

I made my lifting ring using one piece of 1.5”x ¼” flat stock approximately 5.5” long
And 1 piece of T-channel steel from an old garage door track approximately 4.5” long.


1. Drill 2 slightly oversize holes in each end of the 1.5” x ¼” flat stock 4” on center.
2. Cut off a small piece of steel on the end t-channel making a flat for the 3^rd hole.
3. Drill 1 slightly oversize hole in the flat on the end of the t-channel.
4. Drill one hole in the t-channel center for the actual lifting ring.
5. Securely weld the t-channel to the 1.5” flat stock so that the 3 holes are on 4” centers.

That’s it. I had everything I needed to make the lifter except for the 3 metric bolts hence the $2.02 cost. I suspect my lifting ring is strong enough to lift probably 1000 lbs.
I will be posting another thread on how I safely raised the engine by myself with very little effort.
Stay tuned.

Thanks for posting. I started a thread asking about this after a search brought up nothing.

Only $2.02 plus the cost of a welder and some vocational training on how to use it.

Joe:

While I must applaud your ingenuity, the puller you made is relying solely on the bolts and threads to support the engine. This is NOT how the factory lifting eye works, and the flywheel was not designed for this.

JMHO- the method used above is not something I would recommend, as there is a strong potential of damage to the product (and depending on the severity of damage to the product, there is also a potential of INJURY as well).

Read and/or proceed at your OWN risk!
