Old Mercury 50 HP Help

So if it checks out in decent shape I should go for it? Sounds like a little cash to clean her up and it would be worth it. Thanks.

And does anyone know about that trim setup? Looks like the pump is inside the boat and the dash has a three button tilt/trim setup...

Can you put a rope around the flywheel and check the compression?

[tsubaki]

There should be a release valve on the pump to be able to let it up and down manually, if need be.

Great little motors, electrical system can be a pain in the ***.. The trim setup sounds about right for that era, should have 2 rams, one on either side of the motor if i remember correctly.

That is one of the best Mercs made and I have been accused of not being a Mercury fan. But I will admit to owning a bunch of them. The inline 4 cylinder like that one was what I sought out for a tiller motor for my gutted 17' Whaler pickup truck. The motor became the classic "50" in 1986 and actaully had a 40 horspower rating due to the change to prop rated hp. My motor is a 1996 40hp rating but will outrun the porky mercaha 2002 Mercury four stroke 50hp it replaced. Idles just as smooth in my opinon and isn't terrible on gas.

I had a 1987 Merc 50 on a Bass Tracker one time, it was a great running little motor, easy starting, easy on fuel, quiet for a 2 stroke.....I loved it.

Anyone familiar with these enough to help me find a carb rebuild kit? It is an 1982 (serial 5951267) with a tillotson carb. Cannot find any other info on it and it seems like there are 50 different carbs for that year.

Had one on a smaller boat years ago EXACTLY like that...very dependable and strong little motor. I agree with "brushes in starter, check compression, go from there"

My Dad had a 1972 Mercury 80 h.p. which looks exactly like that motor but with red instead of blue trim. Merc did not change those 4 and 6 cylinder motors for quite a while. It was a great motor for about 6 years but then starting having electrical issues. Dad was frequently changing "power packs." He was a PITA with Mercury though, and somehow kept getting Mercury to replace them at no charge.
