Well that tears it! It locked up!

Re: Well that tears it! It locked up!

Got the model number - 40353, which by my research makes it a '63 40hp. Unless one of you more knowledgeable people begs to differ.

Given that a new crank, piston, rings, bearing retainer/pins, and having the cylinder bored out is going to cost me nearly $300 for my '61 motor, (not including gaskets) if this '63 40hp has good compression I think its the best route for me to go. It comes with a boat and a trailer too


BUT.....does that motor have that electric shifting lower unit? If so, can I swap my older style mechanical one in without much difficulty?

If it has electric shift, I would stay away from it, but that is just me. Too bad you don't live close by, I could set you up nicely with a replacement. Some people like their electric shift motors, but things are a bit pricey, if something goes bad and fixing it, would likely cost more than what the motor is worth. All of mine are manual, so I got lucky. In your case, I would swap the powerheads out and stay with your '61 lower unit and mid section.

I second staying away from electric shift.

Fine if you have plenty of experience with them, if you dont, you'll pull your hair out when you have to troubleshoot.

Re: Well that tears it! It locked up!

If nothing else, use the electric shift until it goes bad, then swap the powerhead over. Reseal the manual, while you're out using the electric shift model.

If its a Big Twin, it is standard shift. The Electric was saved for the Lark series...

Re: Well that tears it! It locked up!

Yep, exactly right. 1962 and later and the third number in the model number is a 9 instead of 5 and in the Johnsons, it's an RK model, versus and RD model.

Re: Well that tears it! It locked up!

Well, dragged the whole rig home today. Here's a pic when I stopped at a produce stand on the way home:




The seller said he ran it for a bit a few weeks ago, but it wouldn't start the next day. Compression checked out at 100psi on both cylinders with me using the pull start rope, and the electric starter spun the motor over easily, so I decided to take my chances on it.

Got it home, and decided to pop the flywheel off - it came off with no effort at all - because it had a sheared flywheel key. The ignition looked brand spanking new! $3.89 later I had a flywheel key and had it all back together. I got it to fire for a few seconds, but I think I am going to swap my freshly cleaned carb for this one before I try starting it again.

Will post more results tomorrow.

I love it when I am with a seller and the motor doesnt fire. Watching the sweat start to form on their brow while they yank away, and explain to you that it never does that!

Re: Well that tears it! It locked up!

lol yeah, it always seems that any cars I try to sell run perfectly until a potential buyer shows up.

But this guy was straightforward with me, so I took my chances on it.

Re: Well that tears it! It locked up!

It sounds like you did good. 100psi on both cylinders isn't bad. The motor and boat look pretty clean.

Re: Well that tears it! It locked up!

How the heck did you get compression readings with a sheared flywheel key?

Re: Well that tears it! It locked up!

As long as the crank will spin, that's all it takes.

"I did manage to fight the piston out of the bad cylinder, and after an initial hone things started to look up - the rust came out. It was getting excited, but then I noticed the huge 2 inch scratch running down the cylinder wall. That ain't gonna hone out."

You might trying the hone more, but from what you've said , it wii not work cause that scrach could be a crack if it ever sat with water in the cylinder jacket and frose before you got it. Probley not the case tho if it has been in Flordia its whole life. Just a thought as I get them up here every so often . As for parts, if you cannot find what you need here, try SeaWay marine, They are a old Johnson Evinrude supplyer that has most everything clear back.

Best of Luck on your project,

Re: Well that tears it! It locked up!

Exactly. The '62 and newer had a lot of major changes to the powerhead, and the crank and head being a couple of them. From what a long time mechanic told me, the 1960 - 61 was merely a punched out 35 and they were notorious for twisting the cranks apart, in the event of a runaway situation. A lot were even recalled. Aparently not many went back, because I still see a lot of them out there. LOL

I keep hearing the 60-61's also had bad cranks but have never seen one (and have had several) so I guess they got weeded out years ago and only the strong have survived!

Re: Well that tears it! It locked up!

Ok guys, I have some news.

Today, i swapped out the carb and fuel pump from my '61 onto the 63'. It took longer than I expected due to not having the right tool for those spring-style hose clamps.

Said a small prayer, turned the key, and she fired right up!!

And, stayed running.

The idle could be better, I am going to have to go over Joe Reeves's method of adjusting that slow speed needle again. But, its alive.

Of course, I do have one more issue to solve, which is the opposite of my previous problem - it wouldn't shut off when I turned the key off. :redface: I just suffocated it by putting my hand over the carb, but I'll do some more poking around before I make a thread on it.

Oh yea, there still are a lot of them out there running. I happen to have a nice running '61 model myself and have worked on lots of them in the past. One of which had the top of the crank welded back on. LOL It's not that they had bad cranks, they were just more prone to blow the cranks in a runaway situation.

The ground wires to the mags aren't hooked up. Easy enough to fix.
