1964 Evinrude 60hp Sportsfour

[baldwisa]

My first time here. Just purchased a 64' Evinrude Sportsfour 60hp. Runs and starts easy. Has a hair line crack in the lower unit. Was hoping some JB Weld would hold up. Was also wondering about the water discharge. Looks like it was just "spuddering" out the engine. Is that normal for these old engines? Don't have much to spend on repairs, so any work would probably be done in the garage. If a new water pump is needed, could someone help with a services manual copy of the procedure?

Welcome to the forum! Nice old beast - I had one of them back in the day.
If you're unsure of the history of the motor, I'd replace the water pump impeller as a routine maintenance procedure. Water should flow pretty good, but there won't be a stream like on newer motors - more of a spray/shower. Post a pic of the crack in the lower unit.

You can see the white gear oil dripping out the bottom. The crack is barely visible. I need to get that black paint off to see it better. When I pull the lower unit off to do the water pump, should I replace anything else since it's off already? Any gaskets to seals that should be done?

First thing baldwisa :welcome: to iboats...

As per the gaskets and seal question. I would buy the needed seals gaskets and "O" rings for the water pump impellor change, but unless you plan on disassembling the lower foot section, there probably isn't any others. I would however, change the lower foot oil. And if that oil looks good and not contaminated with water or such, then you are good to go. However, If there is water in the foot or milky looking oil coming out, I would then rework the lower foot too because that indicates it is leaking... Not good!

No Title

Is this the crack? My friend, you have a broken rear stud. I have seen a number of them back in the day. It is important to make sure the upper section of the gearcase isn't bent and that you use a accurate torque wrench to tighten the nut on the replacement stud, or you may break another one. A qualified machine shop can check the case for being bent (parallelism).

 

[baldwisa]

No. It's closer to the bottom. I'm guessing a winter in Ohio claimed the crack with water in the gearcase. The crack isn't that long.

That's odd, I'd expect it to be solid metal in that area. Hard to say without looking at the inside. You might want to try your JB Weld cure. Better yet, Marine Tex. So, you are confident it isn't cracked open where I marked?

 

[baldwisa]

I have a video of the water dripping from that spot. Pretty sure its there.

 

[F_R]

OK, clean it up real good and Marine Tex it.

 

[baldwisa]

Thanks for the tips. I am going to pull the lower unit this weekend and look at the water pump. There is an access plate on the side of the upper gearcase. Ive read that's the access to the bolt that holds the shift rod. Is there any other bolts besides the ones holding the lower unit on?

 

[baldwisa]

What type of grease would you recommend for the grease fittings?

 

[lindy46]

Completely remove the lower bolt from the shift rod coupler. Then remove the bolts holding the L/U and she will drop loose. Use 80-90wt marine gear lube in the gearcase.

For the Zerk fittings use a quality waterproof marine grease. All outboard mfrs sell their own brand name, and all are good for any brand.

 

[baldwisa]

You guys are the best!!!! Here is a better shot of the leak. Sure looks like it was repaired prior. I'll clean it up and do the Marine Tex. I've read these lower gear cases are a real pain to get off.

 

[baldwisa]

How do you remove the lower bolt from the shift rod without it dropping into the case?

 

[baldwisa]

This is what I found when I opened the access plate on the gearcase. Any idea what this is from? Must have broke off something and fell there.

 

[lindy46]

I use a socket filled with grease. The grease will hold the bolt in the socket.

 

[F_R]

So it drops, so what? You are going to remove the lower unit anyway, right? Just reach in and grab it or dump it out. More fun is when you drop it while putting it back together.

 

[baldwisa]

Any idea what that broken piece was I found when I opened the outer access plate?

 

[F_R]

I'd venture to say it is a piece of a broken distributor cap. At least that is where those vent screens are used. Maybe an old one broken in years past (???)
