    Boat swamped, let's see if we can get it running...

    OK, got my fancy pants timing light today. Much easier to set digital than the tiny knob on the other one. Set to 8', verified 23' advance at 2500 rpm. It was bouncing though; not sure if this is normal? A couple of degrees in either direction, only at speed. Steady at idle. Thought it might be...

    No I didn't. Didn't plan on pulling them...They're on their second season. But good thought.

    Perfectly for 15 minutes then, surging, knocking, and jumping tac

    You can swap wires and see if the problem follows the wire. Carb rebuild is pretty easy. Even if you've never done it, shouldn't take more than a couple of hours.

    Don't think op disconnected the tach

    Perfectly for 15 minutes then, surging, knocking, and jumping tac

    Like I said, agree that the immediate issue isn't the flashes (though it may mean the engine isn't performing as well as it could). But how do you explain the tach?

    Perfectly for 15 minutes then, surging, knocking, and jumping tac

    ? Intermittent flashes mean intermittent spark. Definitely a problem. See if you can tell if you're erratic with the light on the coil wire. If not, your problem is with the cap/rotor/wires. If so you have another problem. Agree though that if the flashing is the same regardless of symptoms then...

    Boat swamped, let's see if we can get it running...

    So I rechecked the timing, and it seemed that every time I set it, it was off again when I rechecked it. It was 40' advanced at 1 point, then I couldn't find where it was when I was trying to check advance at 2k rpm... So thought I got it, went out with 2 adults, 3 kids. Seemed sluggish out of...

    2016 Mercruiser 6.2 ECT - long beep every few minutes???

    1. Have you tried disconnecting all batteries except engine batteries? 2. Have you been able to get screenshots of the voltages when the fault isn't present? 3. Was this problem there on the sea trial or did it show up after you got the boat?

    Hard starts after sitting for a week or so

    I thinklutely! It was sitting in the driveway for a week. I think spec is ⅛"or so. But whatever works best for you. Mine doesn't need much if any choke in the 90' weather that I'm usually in, so I dial in a bit more so that it will open fully earlier

    Crank, no spark. Need advice.

    Didn't sound like that's where the troubleshooting led... You never got a spark by tapping the wire or from that last post you don't perform the test correctly.

    Also noticed that on the engine data ignition voltage is > battery voltage?

    Oil Pressure Switch for Fuel Pump - Strange Happenings

    Op switch shouldn't affect cranking. Try wiggling the throttle while you crank (possible neutral safety switch). Next measure voltage at the small yellow/red wire on the starter solenoid while trying to crank... Rather than reinvent the wheel, go through this guide...

    Shift interrupter switch.

    There are a ton of module part numbers that I found, though don't see them broken down by outdrive. Same with wiring diagrams. Which ones are you looking at? And green still shouldn't be grounded, should be the same just without the SIS leg, only from module to distributor.

    Shift interrupter switch.

    The shift interrupt with the TB ignitions works essentially the same as it does with points. The green/wht is the trigger wire from the sensor. When running, the sensor is sending a pulsed signal based on the speed of the rotor. The ignition module then sends a pulsed ground to the coil. When...

    1999 Mercruiser 5.0 L 8 Cylinder not engaging

    Welcome. Sounds like you grenaded your outdrive. Drain the gear oil, look for chunks of metal. Remove the cap at the top of the outdrive to get a look at your upper gears. Could be the coupler also; see if the shaft coming from the engine turns when you turn the prop. BTW, '99 should have a gen...

    help with iffy gas?

    Regular gas can't hold any water. So once you suck out the water on the bottom, there's nothing left. Well, the lower octane makes it easier to pre detonate and grenade your engine, so there's that. Don't want to go too low.

    Shift interrupter switch.

    What exactly is the issue you're having? Sounds like the switch is closing correctly? The green/wht wire should be grounded when the switch is closed. You can check and see if the wire is grounded at the distributor when you close the switch.
