should I crank it over? 50's E-rude.

After 30 years of going out in Miss Ann with my grandad, he has allowed me to bring it home, clean up and restore. 35 E Rude had a head job and good tune about 5 years ago, but has not been cranked over in 2-3 years. Should I put fresh gas to it and see if I can get a crank? Should I try to flush the carbs first? How?<br /><br />I have some experience messing with OMC - also have a mid-50's Johnston 10 HP that still runs like a top. <br /><br />Motor marking are E-Rude Golden Jubilee - I think late 50's model. 35 HP.<br /><br />Any help?<br /><br />Thanks

Definately clean the carburetor. Check your waterpump impeller. Change the gearoil. Pull out the sparkplugs and spray a small amount of storage fogging oil into the cylinders. Crank it over a few times with the plugs out. That'll lubricate it somewhat. Put the plugs back in and see what happens.

Oh yeah, you might also want to flush fresh 50:1 mix through the fuel lines before you put the carburetor back on.

I think that's the '59 model year, the Golden Jubilee. If so, I have the equivalent Johnson 35 hp motor on my boat, an RDS-20.<br /><br />I agree with the previous poster. Do the impeller change before you start on this. Mine had sat fo 2 years when I got it, and I did change the impeller. The old one had taken a set and wouldn't have pumped if I had started it.<br /><br />I'd also drain and change the gearbox oil before proceeding.<br /><br />However, It may not be necessary to overhaul the carburetor before you start it up for the first time. I didn't, and it's working just fine.<br /><br />My suggestion is that you pull the glass bowl from the fuel pump and thoroughly clean it. Check all the fuel hoses for damage or cracks.<br /><br />Do the fogging oil thing in the cylinders, as recommended, then use fresh gas in the tank and give the old girl a trial spin. Mine started after just 5 seconds of cranking. It ran rough for a few minutes, then settled down very nicely.<br /><br />I did end up fixing another problem, but it's performing very nicely on the water with nothing at all done to the carburetor. It's worth a try, anyhow.

Oh, yeah. The proper fuelil mix for that model is 24:1. Don't use 50:1.<br /><br />Also, after you get it running, try adding a full bottle of Sea Foam to the first tank you run through it. It seemed to help mine a lot.

I assume 24:1 is about 2pt per 6 gallons of fuel? I can't run this rich in my 10 HP, it chokes it out. I run more like 50:1. Fogging oil available at any outboard place?

Re: should I crank it over? 50's E-rude.

Yes that's correct. 2 pints or 1 quart for 6 gallons of fuel. CATransplant is giving you good advice. If you want, you can subsitute a tablespoon of 2-stroke oil in each cylinder for the fogging oil. The idea is to coat the bore walls, so do it with the engine fully tilted up.<br /><br />Something must be wrong with your 10hp. All the ones up to '64 have a fuel/oil mix of 24:1 (OMC's recommendation). The '64 one is 50:1, but it had a 10 hour break-in at 24:1 anyway. Course there's no '65 or later ones.<br />What spark plugs have you got in it? The J6C or the J4J? What oil are you mixing?<br /><br />CATransplant - Thanks for the vote of confidence, but I think we could all add a tag line like that to our posts. I know I could have Joe Reeves, alcan, Chinewalker, OBJ, rodbolt, and a hundred others as qualifiers for my posts. The nice thing about the J/E forum is we have all sorts of people helpfully looking over everyone else's shoulder, without having people getting on poster's backs.

Paul,<br /><br />Well, that's true, I suppose, but you seem to have a really good handle on the big twins. I'm still learning, and I've made a couple of blunders...which I won't repeat.<br /><br />It was my father, who is now 80, who suggested that I not bother the carb on my 35 until I had tried it. He's an old hand at auto wrenching and has done a lot of outboards, too.<br /><br />And he was right, too. Nothing wrong with my carburetor at all. The needle was a little sticky, but that went away after a few minutes with fresh gas, the Sea Foam, and a couple of taps on the carburetor bowl.<br /><br />In fact, I haven't even changed the idle and high speed settings. Apparently the guy who had it last had them set pretty darned well. Now...if he had just properly torqued the flywheel, I could have saved a couple of hours of work...but there it is.<br /><br />My neighbor, who is of the 16' boat with a 150 hp motor crowd, went out with me to the lake for my first real lake test for the old Johnson. He brought his 14' tin boat so he could tow me in, if necessary.<br /><br />His comment: "Darn...that old Johnson is sure quiet. And I would never have believed that it would jump that boat onto plane so fast."<br /><br />Right now, his boat is in the shop, with a $2500 bill for overhauling his 150 hp outboard keeping him from bringing it home. I guess we'll be doing opening day of the walleye season in my ugly old Glastron with the geriatric Johnson on the stern.
