    powerpack problem?

    The idle on my engine will not drop below 1200 rpm's. I don'th think the quickstart is cutting out even after the engine is warmed up. Someone told me it might be the powerpack. <br /><br />Questions - what does the powerpack do? Where is it? Is it hard to change? How many do I have?<br...

    cold engine

    Sorry for the long post.<br /><br />Went out fishing yesterday, the water temp was 45 degrees. The quickstart feature on the engine would not cut out after letting the boat warm up for 10 minutes. I eventually just put the boat in gear and ran it out to my fishing spot. The temp guage never...

    Possible prop problem

    Just bought a new prop for my 1990 Johnson 120 (spun the old one). Now every time I get the engine to 5400 rpms it feels like the prop is spun again. If I lower the rpm's a little it runs fine. It is also ok on hard accelerations. Do you think the prop is bad or is there a rpm limit on the...

    "quickstart" problem?

    I have a 1990 120hp Johnson VRO. Sometimes after running the boat when I restart the engine it takes a while for the idle to drop (2 - 3 minutes). Other times it drops in 10 seconds. This problem happens sometimes after letting the engine sit (10 - 30 minutes) and sometimes when I try to...

    Help going nowhere!

    I have a 1990 Johnson 120 VRO. All of a sudden I can't get the boat to plane. Once I get to 3500 RPM's the engine starts to over rev and the boat goes nowhere. I used it yesterday and it was completely fine. Are the gears slipping? How could I check? Could it be just cavitation of the prop?

    max rpm's

    Can anyone tell me what the maximum rpm's on a 1990 120 Johnson VRO should be. I have never exceeded 5500 and I still have a little room to go. I'm afraid if I push it I will blow the engine.

    intermittent tachometer

    I have noticed that sometimes while running, the tachomoter starts bouncing, then dies, then works fine again. From other posts I thought it was the regulator/rectifier but when it dies the volts stay the same. I asked a mechanic and he said it could still be the regulator/rectifier or maybe...

    Regulator/Rectifier - where is it?

    I have a 1990 Johnson 120hp VRO. I am having some intermittent problems with the tach and read the other postings and figured this was the problem. However, I can't find the reg/rec. I can see the reg/rec assembly (4" rectangular flat thing with a couple of wires sticking out). Does anyone...

    Johnson O/B shifting problems

    I have a 1990 Johnson O/B 120hp VRO. The engine runs great but just recently started have a problem with the gears. I shift engine out of fwd or rev into neutral and then shut off. Sometimes when I start engine again it is in gear eventhough the shift is locked in neutral. I'm not even sure...
