Hanging from a lifting eye

[powrguy]

I broke down and bought a lifting eye for my Mariner 135hp outboard. Seems that's the way to go to take the motor off the transom, instead of some straps and finagling a removal.

I also thought of building an outboard stand, to hang it on while it's prepped and painted.

My question is:

Would any damage be done if the motor was hung by the lift eye on a hoist, for a sustained period of time? Is there a thrust bearing issue here, or is it okay to leave it hanging for, say, a two week period while it's worked on?



thanks

Re: Hanging from a lifting eye

i think it will be fine. maybe if anything just lower the motor on to a block of wood just to take a little weight off the lift eye.

Just don't start it while it's hanging on the eye.

Just kidding.

For a motor stand, get one from harbor freight, turn the vertical post around so it slants inward, make an adapter plate out of any piece of scrap metal you have laying around, and yer good to go, and on wheels to boot.

You funny guy !

Yeah; I'm thinking of that, but most of those have the design where the legs on the bottom have one directly in the middle, where the skeg would be, and the height of them may be too short for the motor. I'd have to modify the post height, adding to it, and then somehow mount the motor on that plate you talked about, offset to clear that center bottom rail of the stand.

Seems like making one from scratch would be more custom and would fit better, without all the modifications. I know I can build one out of 2x4's and 2x6's, too, but I thought why go through the hassle IF hanging by the lift eye for a couple weeks was not going to damage the motor

rest it on a block of wood to carry the weight, won't hurt a thing...oh ,we want pictures too !

I've had my XR4 v6 hanging by the hook for months while I overhauled the transom. It won't hurt it. (I have a rail in the shop with an extra truck, so I just hung it and put it at the other end out of the way.)

I've also used the harbor freight rig I mentioned. You can almost get the engine high enough with just the arms on the engine stand, but with a plate it's real easy. You turn around the post so the angle of the dangle is right.

The plate has the standard BIA pattern on it, and another set of 4 holes that clears the engine rails and allows the 4 arms of the engine stand to be fastened to it. Once you get the BIA pattern in it, and the engine hanging and bolted to the plate, you can throw the other 4 holes in with a hand drill and the SWAG engineering method. (Scientific W *** A*** Guess)

If cold storage, or humidity might be involved, be sure to fog it as for winter storage before you shut it down and pull it. You can't crank it when it's hanging, but you can crank it on the stand. I wouldn't let it fire, though.

hope it helps

"The plate has the standard BIA pattern on it".


I'll try to find the BIA pattern on-line somewhere.


Okay, how thick is the plate? Is it 3/8" steel, 1/2" steel? I was thinking of a 2x12 plank as the "mounting plate", or maybe double 3/4" plywood, epoxied together to put on the face of the stand, to hang the motor?


If I welded up a frame, would 1x3 square tubing, with minimum .125 walls be thick/strong enough to hold 400 pounds of motor? I thought maybe if I made a U-shaped base frame, with an H-shaped uprights, with a couple pieces cross-ties between the uprights to mount a 2x12 that it might be strong enough to hold it without worry of finding it on the floor one morning?

BIA Bolt Pattern

BIA Bolt Pattern

I was able to find a drawing for the BIA bolt pattern for outboards, so I thought I'd stick it up here:

Doesn't look like the image will show, but you can go to the link to see it.

Is this what you wanted posted?

Re: Hanging from a lifting eye

I just found a better pattern and did an edit. You got the pic on here, too, so thanks!

Re: Hanging from a lifting eye

I am looking to get a boat with a 96 Mariner 135HP. What can you tell me about this engine performance. Its on a fish and ski boat and thats what I will be using it for, fishing and sking. Does it idle and run good at very slow speeds for fishing and does it ramp up good for sking?

Thanks,
Ken

Re: Hanging from a lifting eye

I only run it with a 3-blade 17p prop on my boat, because I don't use it for skiing. However, I did get a 4 blade prop with it from the previous owner who used it for pulling tubes and skiiers. Plenty of low end torque, and with a correct prop, no problem for skiing. Match the prop to the weight of the boat and purpose. 4-blade props give more low-end performance for pulling skiiers, I guess, but lose some top speed depending mostly on pitch. As far as performance, it idles down nicely, and performs well throughout the range, but, again, match the prop to the useage.

Thanks for the information.

Is the boat attached to the motor as your letting it hang?....:

Yeah; it assures transom is solid and avoids buying boat stands to paint the bottom, too!
