Suggested troubleshooting sequence for no start '98 150 Ocean Pro?

[btravlin2]

Hi All.....I took the boat out today after sitting for 2 months, mainly to get some fresh gas, Seafoam, and Staybil in the carbs. Ran like a top, as always. But after 20 mins or so I slowed to almost idle. After a minute at idle speed, it just quit like somebody flipped a switch, and I had to get towed.

It turns over very strong, it has gas, but it seems there is no spark, because it doesn't catch at all. It seems electrically dead.

What would be a likely troubleshooting sequence to work through? Could it be something as simple as a fuse? And then what?

Thanks......

Optic ignition or standard?

I would check it for spark to start off with and compression test it. You can get a spark tester and also a compression guage at any auto parts store.
Make sure your kill switch did not come loose

I need to learn more about my engine, 'cause I don't know. First thing I'll do is check the kill wire and spark. But it seems like if there were spark and gas I'd have an engine trying to run. All I have is an engine turning over rapidly with not even a cough.

You have optical ignition as ADI ignition was not offered after 1991 on the 150.. below to trouble shoot it.
No Fire at All:
1. Disconnect the 5 wire harness connector from the power pack. If the engine now fires, check the kill circuit and harness.
2. Check the stator resistance and DVA output to the pack.
3. Check the 12V power at cranking on the yellow/red wire going into the power pack. You should read above 11.5V. A low reading indicates a problem in the harness, battery or starter.
4. Check the DVA output from the power pack to the ignition coils. If it reads below 105V, recheck using a Pack Load Resistor. If the power pack output is now OK, the power pack is good but the ignition coils are likely bad.
5. Check the 2 orange wires from power coil to see if fully inserted in connector.

I'll get back after I do down this list. The schematic shows a fuse. I'll check that first.

If the fuse was blown, it wouldn't even crank over. Save your energy.
Do as Fazt says.

I want to make sure. Looking at the top of the PP, I only see two, 6 wire bundles/connectors going into the top of the PP. No 5 wires. Take a look at this diagram. Can you identify which one? BTW, the fuse is good.

Update: I find no 5-wire bundle, but I see the single black wire/yellow stripe coming up from...... it looks like the throttle linkage. I've read about this wire (at least by the color) a lot. Is this the kill wire I should disconnect and then try starting?

Part #39 looks like it might be a 5 wire connector, I wonder if that might be the one you are looking for?

Now I see a 5-wire bundle coming from the flywheel to the PP. Is this the one to disconnect to troubleshoot the kill wire? I want to make sure I don't fry anything.

It's the connector on the port side of the power pack.

Re: Suggested troubleshooting sequence for no start '98 150 Ocean Pro?

I've been out of town. I just unplugged the port side 5-wire plug and it fired up. I had to choke it to stop it. Do I now need to be troubleshooting the ignition switch and safety kill switch? According to the threads here, there is either a short to ground or a bad ground. Sound right?

BTW......if the motor died on me for this exact same reason out on the water, would anything be damaged if I unplugged the 5-wire to get home?

First question...Yes...... Second question...No.

Possible causes: 1) bad ignition switch 2) bad safety/kill switch or tether pulled? 3) pinched wire in harness

Re: Suggested troubleshooting sequence for no start '98 150 Ocean Pro?

Trying to close in on the problem. I bypassed the kill switch, with no change. Now I want to troubleshoot the ignition switch, but I don't know what voltages I should see on the wires coming out of it. Anyone have a link to a diagram with specs?

Re: Suggested troubleshooting sequence for no start '98 150 Ocean Pro?

Pretty simple to troubleshoot. Black is ground, black/yellow is kill switch, grounded to kill motor. Purple is ign accessory. Should have +12VDC on it when key is in on position. Yellow/red is starter solenoid. Should have +12VDC on it when key is in start position. Yellow/black is choke. No voltage unless choke button is pushed.

Key should connect black and black/yellow when in off position, and disconnect them when in on position and start position

Re: Suggested troubleshooting sequence for no start '98 150 Ocean Pro?

Grey is tach signal. Usually it is not connected to the ign switch.
