Re: Just inherited grandfathers 1956 Evinrude 35 hp - I know nothing about it... help

looking for repair manual ect.

Welcome to the iboats forum. The members here are great and the experts, which I am not, can help you solve any problem. Another member posted a link to an online free public library that has lots of manuals saved including one that covers your motor. It is not a "factory" manual but it will get you started and the same one served me well for a complete overhaul of a 1959 Johnson 35 that was seized when I got it.

LOGIN as directed then drill down to: Small Engines, Marine/Boat Motors, Evinrude/Johnson, Outboard 35HP (1956-1964) and Condensed Service Data. Hope it helps you get that great old motor running. Good luck!

Excellent. It's a Lark. I didn't recognize it until you posted the pic of the cowling. I have a '62 Lark 40 on my Feathercraft right now :) Purrs like a kitten:)

I can't find a thermostat for the 1958 35 hp. But there's one for 1959. Would it be a safe bet to say it's the same?
Also I was told there's nothing really to replace on this model except the impeller by Laingsoutboards.com.. does this sound right?
Finally iboats website says I need J8C champion spark plugs however the "clymer" repair manual says I should use J6J spark plugs...

Hi jpm. Great looking motor! You can probably get it running for less than $100. These links may help. Champion J6C plugs should be correct plugs. I believe J8C are too hot and the J6J have been discontinued. The thermostat kit and Impeller you posted look correct also. You may as well order a carb kit while you're at it. You're going to want/need to rebuild the carb after sitting for so long. Good luck. Keep us posted.

Jeff at Laing's Outboards is a good guy, and a really well-respected expert for both 'rudes and mercs. The compression numbers will tell you more about the severity of the old overheat-hopefully not too bad. Maybe a head gasket could be a good idea.

Will I damage the motor if I just toss it on the boat in the water and give it a shot of quick start and try to crank it over?

If, by "quick start", you are referring to starter fluid/ether, then yes you may cause damage. Unlike your 6.2L diesel, two-stroke outboards are lubed by the fuel/oil mix and starter fluid will wash the oil from the bearing surfaces. Use only the same fuel/oil mixture that is in the fuel tank to spray into the carb. In the FAQ's you will find a thread titled "Awakening a sleeping outboard". That will steer you straight. Good luck!

Good point it's no good for diesels either as if the glow plugs turn on while the ether is on them it's bad news...

Ok so for the compression test I'm having a real hard time executing it. The problem is that I have a bum arm. So either it'll have to wait until I can find a friend to pull or i was thinking maybe I could jump the starter with a car battery and jumper cables? Any thoughts on this?

Re: Just inherited grandfathers 1956 Evinrude 35 hp - I know nothing about it... help

You should be able to crank it with jumper cables with the remote control wiring harness unplugged so the igniton coils are not grounded. I would not jump the starter for more than about five seconds at a time without letting it cool a minute or so. Also, from your previous question about the OEM Champion J6J spark plugs no longer being available, it looks to me that the modern equivalent is RJ6C.

FYI, your motor has a compression release mechanism attached to the manual rewind starter that opens a valve in each cylinder and makes it fairly easy to start by hand IF everything is adjusted properly and lubed. On the downside, if those valves stick open the power will be reduced while running or at the very least least produce low results during compression testing. Not being negative, just making you aware of some of the nuances of this particular series of motor. These great old motors do not die easily, they have to be murdered!

The best compression tests are from warm engines. Before running it though I would remove the plugs and spray in the spark plug holes a generous amount of combustion chamber cleaner so as to ensure the rings aren't sticking. rotate the engine by hand several times to distribute the cleaner and let sit for several hours. repeat a few times then flush with a bit of gas/oil. As mentioned before the compression relief system can cause some issues. If it has sat for 15 years there is a very good chance of the impeller self destructing. Cheap insurance to replace prior to running. Also the carb might have residual varnish in it that could become an issue. If you get it running and out on the water take pride in a having a piece of history. If people make nasty comments about the smoke... just say you're not charging them for the Mosquito Control.

Best response I've ever heard to the excessive smoke issue!

I see on the Johnson side the thermostat is the same on the '58 and the '59 35hp. I believe there was only 1 thermostat used for decades actually.

Compression is a high 110 in both cylinders!! Jumping the motor worked great once I figured out that the battery pack I was using had an on/off switch. LOL I thought the starter was dead at first.

Spark plugs in the motor are J4J's which were supposed to be for the 40hp motor. I guess there's not a ton of difference between them.. I'll leave that up to the experts I guess. Time to order parts and hope they don't take too long to get here.

Willyclay: thanks for the wiring diagram!

jimmbo: I did notice there's definitely signs of varnish coating on spark plugs so I will definitely try to clean out the combustion chamber

Fortunately I have experience with that since I drive a 20 year old diesel truck. It doesn't matter that it gets 5 mpg better than an SUV half it's size it matters only that it's smelly.

Good compression - will probably come up by soaking the cylinders with some Seafoam. Those J4J plugs haven't been made in years, so I'd replace them with J4C's or J6C's. That motor should be a good runner once you're done with it!

that old motor is in amazing shape, will be well worth any money spent on it! being that clean , it probably has low hrs.....you will get sooo much satisfaction out of making it run right....it will be priceless.....not to mention....the first time you tow someones $20,000 broken down rig back to shore!! (the designers that made that cowl.....must have been drinking cold beers......it looks like a fridge from the same era!!! ya just gotto love it!)

Re: Just inherited grandfathers 1956 Evinrude 35 hp - I know nothing about it... help

Yeah my grandfather built a boat garage with an exit out one end to pull it with a car and a boat launch ramp out the other end into Lake Ontario that operated with an electric winch. So the boat never spent a day out in the rain. He didn't use it much as it was the last boat he owned. My dad took it 20 years ago with the intention of using it but launched it only one time when he first brought it back. Then it was mothballed and has been sitting on a stand in the basement of his place collecting dust. Again away from the elements. So I'm hoping it won't take much to get it up and running again. Now if only I still had that property with the boat house on it...

Well I can sense a diesel 2 blocks away and the stench is very overwhelming.My throat gets dry instantly, and a horrible taste develops and to top it off, it gets very difficult to breath. Propane is just as bad.

110 psi per hole is pretty darned good. You have a healthy old motor there. I think once you're done tuning it all up it'll do great for ya.
My old Johnson RDSL-21 is pumpin out 120 per hole and that's goin six pulls with the hand starter. LOL
Mine sat for many years under a tree and never got much use, but it doesn't look near as nice as your old 58 Lark there.
