I recently purchased an older model Evinrude Sportwin outboard #10302E-EQ4787.<br />Can anyone tell me the HP and year? I believe it is a 10.<br />The engine starts and runs well enough, but will not shift into any gear. Where can I get repait manuals for this, and what should I be looing at to start to fix my problem. I can't even tell how I would access the area where the shift rod enters the casing under the engine.<br />TIA

Yes, that's a 10hp, built in 1963. Fuel/Oil mix was originally 24:1. Spark plugs should be Champion J4J (now J4C) gapped at .030"<br />Ad <br />More Info <br />From The Old OMC Site. <br /><br />The shift linkage is accessed by removing the little access port on the side of the leg of the engine. If both rods are moving up and down there when you operate the lever, the problem is in the lower unit (gearcase). If not, the problem is either the shift lever itself, or the bellcrank directly underneath the powerhead. You must remove the powerhead to access the bellcrank.<br />The most common reason for having shifting problems is from removing the phillips screw on the lower unit rather than the slot one to drain the gearcase oil. This causes the shift fork to fall out of it's cradle inside the gearcase. If this is the problem, Realigning it usually requires disassembling the gearcase. Unless you have a lot of paitence and luck!<br /><br />You can order aftermarket manuals from Iboats, or somtimes you can borrow one from your local library. OEM manual reprints, which many consider superior to the aftermarket manuals, are available here:<br />TheOutboardWizard<br />Mastertech<br />Marine Engine<br />Ken Cook <br />Sometimes OEM manuals come up on ebay for a fraction of the price of a reprint. Search for "evinrude manual" and "johnson manual".<br /><br />I hope this helps!

Re: 10 HP Sportwin Shift troubles

I have found that on my slightly older model that the lower gear case was stored for a long time and the lower gear case had moisture in it and rusted the cradle, shift lever, and the bushing to the thrust washer together! Bad news for gear cases. I had to disassemble it and repair and replace the worn parts. Got them at the local dealership. Works great now!<br /><br />Check out schematics for my 1958 Sportwin here:<br /><br /> http://1958evinrude10hp.0catch.com/EvinrudeLowerUnit.htm
