    Need info for 1961 5.5 HP Johnson CD-18

    Compression is 105\110. Took flywheel off, everything looks perfect. One coil was definitely replaced, points look new. I made sure point gap is .02''. Put two new plugs Champ J4C with .035'' gap. (CAN ANYONE CONFIRM OEM RECOMMENDED PLUGS AND GAP FOR THIS MOTOR?) Got strong blue sparks...

    Need info for 1961 5.5 HP Johnson CD-18

    Hello, I just got this motor in very nice condition, but it does need good tune up. This is first OMC I got older then 1967. All manuals I have start with 1965. I did some web searching, but found details that differ. Can anyone confirm if the info I have is correct? 1. Spark plug : Champ J4J...

    1979 85 HP Johnson V4 blows fuses

    I was down sick for a while and now got back to this problem. I disconnected red plug and connected spare RC. Fuse blew after a few starts, so it was not a key switch. By playing with it I found that pushing in for choke causes the fuse to blow. I removed choke solenoid and connected voltmeter...

    1979 85 HP Johnson V4 blows fuses

    I have exactly the same RC from spare 50HP, so I will disconnect it at the red plug and reconnect just a new RC plug to make sure short is not on the engine itself. Then I will try to see if it CHOKE or START that blows it. Then I can even swap the switches (I have a wild guess that it will be...

    1979 85 HP Johnson V4 blows fuses

    Hello, I took my boat to the lake today first time after the winter. Before that I started motor (85ML79R) with muffs and it ran fine. Spent a few hours on the lake and it worked fine. I was getting 30 mph max instead of 34 mph as last season, so I decided to run it again when I got back home...

    1979 5 HP Mariner question

    I disassembled it again, filed and cleaned points, checked every wire, put everything back. One thing I also did: put electric tape over worn grommet where HT lead goes to coil to prevent it from moving and leakage. Got nice blue spark! Motor starts with one pull. Ran it in the tank and adjusted...

    1979 5 HP Mariner question

    Spark plug is new NGK B7HS. All gaps checked to specs above. When it did not start after a few pulls I suspected fuel issue because I knew spark was there. I injected fuel into cylinder manually and it was not even sneeze. So, it is "no spark" issue and the question is if coil died or something...

    1979 5 HP Mariner question

    Hi , I finally got the manual and spent some time on this motor. Compression was high - 160 psi. Carb was dirty and needed good soak and rebuild. Now the problem: Before I started taking it apart I put new spark plug, grounded it and pulled rope to see if coil is good. I got good spark. Now...

    1979 5 HP Mariner question

    Hi, I got 5 HP air-cooled Mariner outboard today. By SN 661-316002 I determined that it is 1979. I had 1983 15HP Mariner that was made by Yamaha and had 1984 twin Yamaha brother what really helped for finding parts. I also used Yamaha repair manual that was easy to find. This motor also says...
