First off, this motor was a throw-in to sweeten a deal on another motor, or in otherwords I have nothing invested. She runs very well, nice and smooth, and starts easily.

Here is the mystery... if you look you will see that the head is sealed with JB Weld!!

Here is the question: I want to sell it, BUT I also want it to be reliable, and I just don't have any experience with the grey goop on an outboard.

What would you do ???? also do you see the bright blue half of the powerhead?? is this a clue to the head needing to be sealed ???

Well that's a first, someone did some red green on that sucker. If i were to take a guess the head is badly warped and instead of replacing the head or sanding it flat they jb'd it. It need to come apart and inspected, that's if you can get it apart!

Looks like a Johnnyrude! I'd be hesitant to sell it in that condition, other than to sell it as a parts motor.

That's pretty nasty. I guess that is why they threw it in for free. If it was me I would take a fair bit off the price and let the buyer know the issue or just use it myself. If it has good compression, I imagine there are quite a few buyers out there that would never attempt to remove the cylinder head and I doubt it would be worthwhile to take it to a mechanic, so for a good amount off the purchase price, they might love it.

Also, there is no such thing as a 1965 5.5Hp motor. I am pretty sure they stopped calling them 5.5Hp in 1964 and decided to round up to 6 Hp in 1965. So if you are going to sell it you should find out the proper model. If you give us the model number, we can give you the year of manufacture.

Model 6502S is a 1965 6hp Evinrude. Frankly, if it were me, I'd remove that head in order to find out exactly why that JB Weld is there. If you can fix it properly, fine....... and if not, either keep or sell it as a parts engine. Otherwise your reputation will go downhill fast and what little profit you might make temporarily isn't worth it.

I agree with this entirely.... I won't sell a problem to anyone, and this could be a problem. What I will do is take the head off, and inspect, then report back and tell you what I found.

Take the head off, clean the JB off and check it on a flat surface, i have had success on a window but have been told it's not truly flat. Heck it may have been used in place of a headgasket, PO was probably too cheap to put one on.

Sell it off as a "junk" motor. Fully disclose what u know and tell the buyer its junk. Let them decide if it is or isnt. Not worth the headache in my opinion unless u have cabin fever, a machine shop, and spare parts. Value? Idk 50 or so, 75 to right person.

-8.... Leave it alone! You stated...."She runs very well, nice and smooth, and starts easily."....

It's a 45 year old small outboard motor - and runs great - leave it alone. I've seen too many outboards hit the dumpsters because all of us are Perfectionists - I'm Guilty as charged.

In all fairness, run it hard on a boat to ensure nothing blows up, overheats, or hits the spark plug... and give a fisherman on a very tight budget a chance to get out on the water (enclosed waterway). Given your Pedigree, it's plainly obvious you'll let the buyer know the status of the motor.

Someone's been in that motor so it's probably got new rings and more, very nice given the age.

I'm aware of a hand full of heads that have been MarineTex'd. Salt had corroded the block mating surface, Aluminum block had chipped(around steel liner) and owners that were looking for more power (via compression). ALL ran long enough to justify the intended mod..

Think Mercury and their gasket less block system and that's what you've got. It would be interesting to know what you get for compression - if you've got a gauge.

If the motor runs OK, I would leave it alone and sell it for a very low price or simply give it away. Obviously disclosure of issues that you know about, is appropriate.

I can't quite figure your motor out. The cylinderhead is definately off of a 6hp OMC. There are two cues there - the bypass tube down the back of it and the angled spark plugs. The flywheel is also from a 6hp engine. What is strange to me, is that the rear portion of the powerhead casing is the red Johnson color that was used on the 5.5hp motors. The blue paint on the front half of the casing doesn't look like a stock paint color, so it could be a matched casing, but it also might not be. The read pant could also be undercoating - I'm trying to remember how late in the 60s run of motors this was used.

To complicate things even more, that red rear casing has a fuel pump mounted on it - something that the 5.5 hp motors didn't have. So, if there are mounting and pulse air bosses molded into the rear casing, its a 6hp casing. If there is some sort of an improvised mounting point, its not.

If you have more photos that you can post, it might be interesting to see the rest of the motor.

Well, myself, personally, I would just remove the head and get the JB Weld off and re-install the head with a new gasket. No biggie. At this point, you'll be able to sell it as a running motor and not have to worry about your reputation. If it runs great, you're all the better off with this selling point. Fixing the head situation won't hurt anything. Even replacing the head entirely, won't cost a whole lot either. Maybe the head was JB Welded, because of a crack or something. To JB Weld, in place of a head gasket is just plain nuts.:eek:

If you don't need it, I'd sell it but disclose the JB issue. And Jay, all of the 60's 5.5's did have a fuel pumps. They stopped using the pressure tank after the '59 CD according to the parts manuals I have.

With this kind of fix on the "free" motor, I'd be worried a lot about the motor you paid for. How many cobbled up repairs can you find?

Jay,

I have a 72 6 HP that I am rebuilding, and my head/block has a red coat (primer?) underneath the green OEM paint.

I also agree with your assessment of it being a 6. Mine looks dang near identical.

I completely agree. Who knows what you might find on the motor you paid for. Hopefully all is well with it.

I have a 1961 model 5522 and the original paint matches yours with the underlying red primer. As for the blue of the rear case, who knows.

Whatever you do, it is a fantastic little engine!
