1999 Johnson 35 hp starting problems

[firefighter13]

I have a Johnson 35 hp with electric start, I am having starting problems, the motor rolls over has more than enough spark, however It will not start. I have a few wires which aren't connected to anything, there are 6 wires, 3 coming out of seperate casing( 2 casings with 3 wires each) are these something that could cause it not to fire? Model number is: j35pl3ssb ser no: g 0472779 the wires are: white with orangish strip black and solid purple in one case and black gray and solid purple in the other

I am assuming that this is a new to you engine?

First off as the oil tank and mixing chamber been removed? If it hasn't it needs to go. They are very prone to failure run your engine on 50:1 pre-mix. If your spark is good you need a fully charged battery if the battery is weak it will not spin the motor fast enough to start. Have you checked the compression?

The wires you are describing are at the controls the black, purple and grey are for an aftermarket tach. The black, purple and white/orange are for a trim gauge. There should be insulators on the the purple wires, the grey wire and the white/orange wire so the so that they cannot short out. The black wires are grounds.

Here is the proper way to start your outboard.
Your engine is equipped with what OMC called QUIK Start. Squeeze the fuel line primer bulb until firm. With the engine in neutral and the idle lever all the way down turn the ignition key to the on position. Wait for the system check alarm to beep as it cycles through its checks. Push the ignition key in and turn to start. Once the engine is running you can lift the fast idle lever you might need to pump the the primer a couple of times to keep the engine running.

I am not getting the beep. I have bought an after market ignitions because I got the motor second has and it didn't come with one, what are some thinks I can look at to figure out why I get no beep? And yes the mixing chamber has been removed. Thanks for the help guys!

Re: 1999 Johnson 35 hp starting problems

Do you have the proper BRP / OMC controls? Based on the wiring you described it sounds like you have the harness from the engine to the controls. I believe your are missing the system check gauge and horn which means no beep. Photos of what you have will really help.

Re: 1999 Johnson 35 hp starting problems

I also have a plug that is for an 8 pin plug that is not hooked up... What is this one for?

 

[firefighter13]

Re: 1999 Johnson 35 hp starting problems

. I know the 6 pin is ignition and 3 is trim.

Re: 1999 Johnson 35 hp starting problems

I have the horn just no gauge I guess

Re: 1999 Johnson 35 hp starting problems

The system check gauge uses the 8 pin connector. For the horn to function you need the system check gauge or there is a black boxyou can also use. Yes the six pin is for the ignition switch and the three pin is for the trim and tilt. With the proper OMC / BRP controls it is plug and play.

Assuming motor will not start without the gauges? I just bought one

Re: 1999 Johnson 35 hp starting problems

Is it the lack of the gauges/ system check not working properly as to why my motor won't start? Have tried everything and it is all perfect compression spark starter everything is fine. Will not having a system check guage be stopping the motor from starting?

Re: 1999 Johnson 35 hp starting problems

What are you using for controls? You said you have an after market switch is it the BRP switch and connector? The system check gauge is not needed to get the engine to run it is required for the temp alarm. The horn won't work without it. The more photos the better.

It could be a simple problem have you tried spraying 50:1 premix down the carbs and seeing if it will fire?

Re: 1999 Johnson 35 hp starting problems

Tried that, tried just about everything. I had it started for a few seconds then it just died and won't start again, the gas is a 50:1 ratio

Re: 1999 Johnson 35 hp starting problems

I bypassed the connected and spliced my harness directly to the ignition and removed the 6 pin connectot

I assume you have the key wired the same as the attached drawing. You have to have a key that pushes in to activate the priming circuit.

Do you have the BRP / OMC Service Manual if you don't you are going to need it. These outboards are great once they are setup and everything works but without the manual they are pain as there is very little third party documentation available.

Check you fuel hose routing under the cowl. The hose from the second fuel pump should route behind the engine on the starboard side through a fuel filter and then over to the fuel rail on the port side. The fuel primer pump is also the port side and it as a little red arrow. The arrow should be pointing to the bottom of the primer solenoid. If it is pointing up or towards the fuel lines it is in bypass mode. It sounds like it isn't getting fuel or you have multiple issue.

Check all electrical connections make sure the black and yellow wire is not grounded out on anything and that all connections are clean and tight. If you go to page 57 of the CDI guide (see my sig) Follow the TS instructions for the V4 / V6 with optical ignition the small triple uses the same ignition system but there is no write up for it.

Re: 1999 Johnson 35 hp starting problems

Just figured out the arrow is pointing up, could this be my issue?

that looks the right position to me

Re: 1999 Johnson 35 hp starting problems

That is correct

Re: 1999 Johnson 35 hp starting problems

Oh. Back to square one then, I put it the other way and the motor did back fire,
