Older Evinrude Fisherman 5.5

[The RealRookie]

My dad just picked this motor up for me at the fleamarket for 100 bucks. It runs great and stuff, came with a nice metal tank that cost almost the price paid, but i have some questions.<br /><br />First, no model numbers on this, just a serial: 5520-19824<br /><br />Mixture needed please. I ran it on 50:1 and it ran fine, but i think these older ones are lower mix?<br /><br />Also, the turn tension is to tight. I cant figure out where to loosen it so its easier to turn.<br /><br />Thanks folks, for any help

That's a 1960 Model. Ratio is 24:1 Mixture. You can find more info at the link below: 5520 is the model number. Put that model number into the Database section .<br /> <br />web page

You've got yourself a 1960 model. Fuel mix is 24:1.<br />Backlash

Thank you. Any place online to find out about the tension?<br /><br />Is there a thermostat in this motor? Asking because it didnt flow water right away. I was shaking in my boots for a few minutes<br /><br />Does this require any special 2 stroke oil or is tcw3 ok?

Hi Rookie,<br /> TCW3 oil is fine. <br /> I would go ahead and replace the waterpump impeller as a matter of course. The impellers are inexpensive and relatively easy to replace. Try your local library for a general service manual. I'm not sure if anything I-Boats has would go back that far, but it's worth a look, too.<br /> As for the steering tension, there may be an adjustment screw up underneath the clamp brackets. If it has one, it would be a slotted fillister head screw with coiled spring under it. There should also be a zerk grease fitting under there somewhere. If that doesn't work, try some heat from a propane torch on the steering tube. Not too much, as there are some fiber bushings inside that can be damaged. You basically want to warm up the grease and get it to flow a bit to loosen things up.<br /> If those don't fix it, then you'd need to disassemble the tiller bracket (not hard, and you have to take the powerhead off anyway to do the waterpump), clean all the parts, and re-grease everything.<br />- Scott

Re: Older Evinrude Fisherman 5.5

Will i blow this engine up running it on 50:1? Was told i would. Though i plan on mixing the proper mixture today, was just curious if something like this was true. If its true, i dont understand how to much lube can hurt.<br /><br />And, since this engine is so old, should i have a lead additive?<br /><br />Thanks<br /><br />Edit, ah, nevermind about the lead. I jsut read some of the FAQ again and found my answer.

Re: Older Evinrude Fisherman 5.5

Hi Rookie,<br /> Yes, you WILL blow your motor up on 50:1. May not happen tomorrow, but it will happen. Some folks may tell you they've been running their for years on 50:1 using junk gas and griller grease, but they're running on borrowed time. 24:1 - MAYBE as lean as 32:1 if you're using premium oil. It's about lubrication, but it's also about sealing. Your motor has no seals inside and requires oil to act as a sealant between top and bottom crankcase chambers and in the upper and lower bearings (bronze babbit bearings).<br />- Scott

Re: Older Evinrude Fisherman 5.5

I think i figured it out. The grease nipple on this looks pretty worn and wouldnt take grease. I tore her down and think ive found the problem. Inside the shaft there is a rubber sleve on the bottom and looks to be a metal one on the top. The one on the top is where the grease nipple is and it looks like the little hole in the upper sleve at one time linned up with the grease nipple. <br /><br />Is my thinking right? Im not really sure how im going to fix this. I "think" i have 3 options here. I can either drill straight thru the nipple, which doesnt have a little ball in it, and thru the sleve so it has a new hole to line up with the nipple.<br /><br />Or, i can try to turn the sleve inside the shaft (eeeeek, sounds like DANGER), but im new to this and i will probably break something other than the 2 bolts already broken. <br /><br />Or, i can remove the entire nipple thats already there and tap in for a new one.<br /><br />It looks like i might need a new gasket to put the power head back on. I havent dug into the lower end yet to get at the pump, or check the lower end lube and seals. The lower end is a little darker in color, like someone bolted it on from another engine or something. <br /><br />But hey, my first tear down. Man its a dirty job.
