One of my friends give me an 15 hp Evinrude outboard, painted grey, 'FİFTEEN' written on the front side of the hood. It's shaft is short.<br />Firing up is vey hard, generally it doesn't give response to throttle, sometimes it is running well<br />but generally it is working choked. But the choking system is working well. What are the specialities of spark( cold, hot etc.)how can I understand the make year of the engine? How can I troubleshoot on it?

Alone.... You should check the compression and spark, and also the lower unit lube. Do not remove a philips screw if it exists in the lower unit skeg as that is a shoulder bolt shift lever pivot point screw.<br /><br />You can check the copmpression with a gauge (prefered) or simply feel that the compression is sufficent and even on both cylinders. If with a gauge, it should approach 80 to 100 psi.<br /><br />The spark should jump a 1/4" gap on a magneto system and a 7/16" gap on a CD ignition system (with the spark plugs removed).<br /><br />Your explanation of the problem indicates that you have a fouled, clogged, gummed carburetor. If so, the cure is to remove, clean, and rebuild it.<br /><br />To find out exactly what the engine is, we will need the model number. It should be located on a plate on either the left (port) transom bracket (the bracket that attaches to the boat), or on the front of the swivel bracket (the bracket the engine turns/swivels on). There may also be a core plug (looks like a small quarter size freeze out plug) on the powerhead itself with that same number.<br /><br />Once we know that number, you can obtain a manual, gain information about the engine, order the proper parts, etc.

OK Joe,<br />Thanks for detailed advisory, I will try for repair and tune up. I can do whatever ı want to a chevrolet V8's Rochester but I am very rookie on outboards, two cycles, and oil mixturing to the fuel... I will take the serial number and write again.

Alone..... I do not need the "Serial Number". The "Model Number" is what is needed to determine what you have. However, list all of the numbers on the plate and I'll sort them out.

Hi alone!<br /><br />From that model number I got this: <br />#15702 15HP year 1967. <br />From here:<br /> http://www.marinshopen.se/guide/omc/evin6.htm <br /><br />According to this web site there was no 1967 15HP:<br /> http://mitglied.lycos.de/old_omc/e_1967/evin_1967.html <br /><br />Try to find some similar here:<br /> http://mitglied.lycos.de/old_omc/oview.html <br /><br />What do you mean by veteran, 1920, 1940 or 1960?<br />As you know we need the year first.

No need to be sorry. I'm just trying to find out what you have. Maybe it isn't from the 60's at all. It can be vintage, veteran or just 25 years old. <br />It doesn't look this old this does it?<br />

Alone..... Model number 15702 does not exist. However Model number 15704 does, which is a 1977 15hp Evinrude. Is it possible you misread that number?<br /><br />Is the hood metal or fiberglass? Little by little, we're getting there.
