'86 Johnson VRO90. About 2 1/2 yrs ago I started having problems with intermitant spark<br />Once the boat started it would run for hours. I should also mention that this engine is on<br />a '40 houseboat moored on a bouy. I thought that the prob was with the lanyard swith at<br />the control, so I bypassed it. Still the same problem. A marina mechanic came out and <br />looked at the motor. No spark to either bank. He checked the 20 amp (?) fuse and it was<br />good. He condemmed the stator (timing base). I replaced it but was kind of leery when the <br />guy who sold it to me said he had never sold one before. Still the same problem. Sometimes<br />spark and sometimes not. His next idea was that the Amphenol plug between my control and <br />engine was corroded. My cabling is in conduit, so its not that easy to check. He lent me<br />a "known good" cotroller and I plugged my engine directly into it and still no spark on either <br />bank, I took the chance that both power paks had gone out at the same time and replaced<br />the starboard pak. Still no spark. I've changed to timong base back and forth between the<br /> old and new at least 3X. Ive metered every wire at the control and they all seem to have<br /> on them what they are supposed to have. Ive replaced the flywheel woodruff key and<br />have resisted the temptation to cut the black with yellow tracer (lanyard ground) off the <br />power paks. I need help on determining what the Ohm value should be on the stator, power<br />paks, etc. The 20 amp fuse I've metered 5X and it keeps looking good . I'm no pro, but<br />a fair "shadetree" and this (my first and only outboard after 40 years of boating) is close to<br />beating me. I can't exactly haul this boat down to my nearest shop. Also, I don't have<br />a shop manual and neither does my three closest shops.
