i am thinking ok ready to start no!!
i have good hot battery, fuel and oil; but only have fire on left bank and no fire at all on right bank. i have put on a new power pack still no fire on right bank, about ready to go to a mechanic, but first any ideas from ya guys.

Re: 92 johnson gt 200 no start

You have a shift assist switch behind the shift lever that shuts off one bank of cylinders when you shift out of forward gear; it may be out of alignment.

You can disable it to test by disconnecting the black ground wire, but be careful, it can make shifting into reverse very difficult.

Re: 92 johnson gt 200 no start

i found a switch under the shift lever that had 2 wires, one black and the other blk/yellow. i followed the blk wire back an it was grounded to a bolt above the coil. i took that blk wire off and cranked over still no fire on right bank. the blk/yel wire went to sm. plug next to the power pk, i unplugged that and stil no fire. i also took loose the big red plug and jumped it over thru starter and still no fire, i am thinking i am in trouble now. any more suggestions?
thanks

Re: 92 johnson gt 200 no start

There should be a black and yellow kill wire plug on each side leading to the powerpack; you might want to try disconnecting both.

If both were disconnected and the engine starts you will need to choke the engine to stop it.

You can download the CDI Electronics Troubleshooting Guide and follow the instructions for your motor: Just save it to your disk first to save time because it's big: http://cdielectronics.com/Downloads/tabid/55/language/en-US/Default.aspx

Re: 92 johnson gt 200 no start

You already changed the PP , the manual says its time to test the charge coil output.

You need the factory service manual and a DVA adapter for a multimeter to do this test.

Heres a circuit diagram to make your own DVA adapter, its VERY simple, only 3 components and a bit of wire in a little box.
I built one in 30 minutes, I'm a chef not a tech.

The resistor is 1.2 meg ohms, get it all at ratshack. Total cost $5.
Or pay a mechanic $800 to do the same thing.

Re: 92 johnson gt 200 no start

i did not realize there were 2 plugs, i will try and unplug both and see what happens. it is getting dark here in tx, so tomorrow it is, for now i will go to web site suggested, and try to learn more.
thanks

Re: 92 johnson gt 200 no start

i have a multimeter to test the charge coil and i have 2 manuals, a seloc and clymer but not a factory one for my motor. i don't think i am smart enough to check the coil with multimeter, but i will do some research on that chore and go to website for making dva, thanks for your advice. my dad taught me things about cars and motors, he said "girls should know these things" but he didn't show me multimeters, so off to research.

You can buy the DVA adapter if you don't feel up to soldering your own, you can see theres nothing to it.

Heres some good reading for the 60 degree looper ignitions.
It shows how to test.

Re: 92 johnson gt 200 no start

got an early start on this no start problem, i decided to take power pk off and check every connection and clean for good contact. i found 2 questionable wires coming out of the rear of the power pk, i had 4 rubber plugs coming out the back of pk, 2 on each side, 1 on top of each other. on the right side(no fire), there was one wire that had a gash in it i repaired that. put pk back on after good cleaning of connections and i now have fire. it just takes a small prob in a wire to mess everything up. i want to thank everyone for there help this is a great place to go for answers.now with that prob solved it is on to more fixing. i am gonna try to replace water pump, does anybody know about how much this lower unit weighs? i am worried about being able to hold it when it decides to drop, and putting it back in.
thanks

Re: 92 johnson gt 200 no start

they are fairly heavy. put something under it to catch it. block of wood. then you can see if you can handle it yourself. even a floor jack just snugged up to it.

Re: 92 johnson gt 200 no start

reading manual now on removing, it shows picture of big burly man taking it off, not a skinny little man. that was first clue of it being it heavy. i have a floor jack i will use that, these manuals can be alittle confusing!!
thanks

Re: 92 johnson gt 200 no start

hope you are using the Johnson Manual, the hardest part is disconnecting, and reconnecting the shift rod. lower your trailer tongue to the ground.

Re: 92 johnson gt 200 no start

Disconnecting and reconnecting the shift rod is easy if you remove the port side lower engine cover first.

Re: 92 johnson gt 200 no start

i have the lower unit off and i am now getting the pump housing ready to slide on. questions 1-- i have a o-ring left over no good. the pump housing cover i have a o-ring inside and then i placed the housing liner into the cover. then it says place impeller into housing going in right direction, i did this, it sure is a tight fit! is suppose to be snug in there like that? you can't move it with your hands once it is in there. so i have accounted for 1 o-ring inside cover, and i have another o-ring on top of the shinny plate which i secured to the lower unit.(so i have paper gasket, then shinny plate, then o-ring). so is there supposed to be an o-ring in between the liner and top of the impeller? i have a picture as soon as i figure out how to get it up here. thanks

Re: 92 johnson gt 200 no start

well my lower unit is ready to go, all cleaned up, new water pump kit, new gaskets on the exhust flange thing, everything is ready to go, can't put it back up in the motor. the one guy was right for me anyway, it's easy coming down but a bitc--------going back up. couldn't line everything up that needed to be done. so i know when to acknowledge defeat!!!!! off to the mechanic i go, he will probably charge double just for a box of bolts and giving him a lower unit in hand. i have learned that lesson for next time.
thanks guys for all help, hey i have spark now!!
