Mercurys - what to do? 07 Dec 2017 01:25 #80142

Gasserx, where are you located? I would buy a 402 for parts.

I'm in upstate NY.

Mercurys - what to do? 02 Sep 2017 00:15 #77578

Well, I guess I have to differ quite a bit. As a Mercury dealership for more than 50 years, we certainly sold some of these outboards, as the 40, and later 35 horsepower at the propeller rated versions, were made from 1970 to 1993. The 1970-71l 400 model certainly had some issues, but revisions creating the 1972 402 models ended the previous issues. As these outboards were only 33 cubic inch piston displacement, way too often they were really too small for the job they were supposedly to do, being "lugged" they are likely to break the crankshaft, but I have seen other outboards to do so when abused to the level involved, so on a light-weight boat, being "propped" correctly, I do not have an issue with them. Certainly rotten wiring is often the cause of "blown" ignition and charging components, as with other horsepower models. As said earlier, being 35 horsepower and 33 cubic inches, it is silly to see them installed on regular size pontoon boats, as they were very often sold by others on, being that they could not be "propped" correctly in such a usage, one is silly to expect any outboard to "last" with such abuse.


A Happy Labor Day Holiday To All,

I owned 2 of those in the past. The last one was on my FC when I bought it and I could not get rid of it fast enough. Wiring, stator, switch box all went bad on the one I had first and ran for a few years. The only good thing I can say about it had a lot of wallop for a little 2 cylinder engine...when it ran.

I was given a 402 years ago that looked like new.
It made a funny noise when last operated.
I tore it down, and the crankshaft was broken in half.
I heard that they had issues with them, so I junked it.

They are mercury 402's
40hp two cyl

Not a great motor
Most merc fans despise them
I cannot attest to their weakness/failings but I think it was carb related
But they are to a mercury what YUGO was to a car
List them on the John's Old Mercury site
Good luck

These was delivered to my house yesterday.... got them for free from a friend. Its FIVE Mercury 40 hp outboards. I havent checked the serial numbers yet, but i believe they are from around mid 70`s to early 80`s?

But what should i do with them???? :yikes:
Should i try to build one good engine out of the 5? And if...how do i choose the one to start with?
