Gotta hillbilly my way through an outboard lift.

Hey guys, trying to get an outboard swap accomplished this weekend and I don't have the proper outboard lifting eye. Engine is a 2016 Mercury 90hp (360 lbs). Does anybody know what size and thread pitch these three bolts are? If I can find something that matches the 3 bolts I can make this happen. Thank you.

There’s no hook on the motor instead of the flywheel? My 2012 merc 90 had one. I just used a shackle and chain hooked to a forklift

Measure the diameter of the bolt hole.
From there you can get the pitch from a table off the web.
Every diameter will have a fine pitch or a coarse pitch. That you have to figure out. It is usually pretty easy to tell whether it's a fine pitch or a coarse pitch.

Do you have a tap/die set they usually come with the gauges to check pitch. Worth purchasing if you don’t have https://www.canadiantire.ca/en/pdp/...tric-carbon-steel-86-pc-0587201p.html?loc=plp

I have some random taps, but not a set. I should invest. Thanks.

I belive its an m10 x1.5

Well, I ended up finding three bolts that fit. Laminated a piece of plywood to a chunk of 2x10 and drilled holes for the bolts. I used large washers on the top side of the plate and drilled and installed a threaded rod with an eye bolt for a pick point. World like a charm, hung relatively level and cost about 15 bucks in hardware.
