Proud New Owner - Questions for Xperts...

[prginocx]

Finally found the right motor. 4 HP Evinrude, 2Cylinder, 2 stroke. I believe it is late 70's vintage. SN E0009234 and Model NO. E4BR4CNR. <br />Seems to run smooth and start really easy.<br />Compression top = 55<br />Compression Btm = 60<br /><br />Can anyone tell me what year this motor is ?<br />Where can I get an owners / service manual ?<br />What is a good way to de-carbonize the cylinders ?<br />How the heck to I get the cowling off ? I can lower the bottom housing, but how do I remove the top cowling ? This guy has some sort of wierd two piece housing.

Howdy, prginocx.<br /><br />That's a 1982 engine.<br /><br />Manuals can be had from kencook.com.<br /><br />Decarb is covered well in the Engine FAQs.<br /><br />Good luck.

Top cover comes off with 4 bolts,from underneath.DON'T pull that phillips screw on top.It holds the starter (and rewind spring) in place.<br /><br />DHP

With the lower cowl lose, look up underneath toward the top. I believe there are four screws holding the top cowl/starter in place. They have to be removed with a long screw driver. Wierd set up.<br /><br />Here's a link to the BRP site. Click on engine diagrams and follow the prompts. You can at least get a parts break down for your engine.<br /><br /> http://www.evinrude.com/en-US/ <br /><br />And I think that second "4" in your posted model number is really an "H".

You guys are terrific. I swear my huge phillips was just about in that big screw...<br />I once took apart the recoil spring on a Force 5HP motor, thing took off like a frisbee. Way fun to rewind.
