You've probably seen my mercury 850 posts about flywheel pullers and lifting eyes.<br /><br />I've come to the conclusion that getting the flywheel off is not the obstacle and lifting the powerhead is the real problem.<br /><br />Is it safe to lift a merc 850 by threading something on over where the flywheel nut is. For example, take the flywheel nut off thread a long nut over that has a ring welded to it over the end of the crank and lift by that.<br /><br />I'll get this figured out and leave you guys alone soon.

I would say no, all your force will be on your crank and seals. There are always threaded holes on blocks to insert a large bolt or two for the purpose of lifting..but don't lift on that crank!

my merc 150's and older 175's had a 3 bolt pattern on top of the flywheel for the lifting eye to be bolted to.... your pulling on the crank when using the lifting eye, motor is balanced etc. I don't know about your model, but I expect the lifting eye is to be bolted to flywheel also, which will pull on the crank when lifted...

Yeah, there is actually a mercurty part number for a lifting eye that threads into the center of the flywheel. I thought that lifting by the flywheel is the same as lifting by the end of the crank. I would assumt that mercury designed to be done this way. I just wanted to make sure that it would be the same thing.<br /><br />I'll probably be buying the lifting eye. Mercury part.

Hi<br /><br />All newer Evinrudes V4 and V6 are lifted by lifting eye attached to the flywheel and threrby cranck - no problem its less than 400 lbs - forces on cranck when running are much, much higher.
