Greetings,
Still somewhat new to this board but most thankful for it's existence.
I have a 1966 Evinrude 5 hp (5602R) that came with a boat I traded for recently. I changed the spark plugs (5 engine hours previous). When checking for spark (plugs removed but connected) found the spark on the lower cylinder to be weak and intermittent compared to the upper cylinder. Today, while decarbing (with a barrel of water) I pulled the plug wire from the lower plug with zero effect. Cylinder not firing... after replacing the plug wire, I pulled the wire from the upper cylinder plug, engine dies. Pretty obvious that there is no spark/ignition in the lower cylinder.
Since I have no manual, I'm not sure where to look... I assume the flywheel needs to be removed and some form of points/condensor system needs checked and/or repaired. Don't have a wheel puller to pull the flywheel, but might use my harmonic balancer puller instead.
Also, the engine is spitting milky (oily) residue from the exhaust ports, and the cooling water discharge is weak to say the least. Oil from the non-firing cylinder? Or possibly gear oil from the prop gear assembly? I checked the oil in the gear assembly and it appears normal (not milky, as in water- contaminated).
The motor appears to run well on one cylinder... I trolled for 5 hours a couple days ago and no problems other that an occaisional "sputter" (apparently the intermittent firing of lower cylinder).
Any thoughts or recommendations would be appreciated. Also, location of the impellor would help.
Thanks in advance!
