    What is this filter on the ignition power wire?

    Okay thanks, would a general purpose 50v 3a diode work?

    What is this filter on the ignition power wire?

    I’m trying to chase down an electronic noise issue and I noticed this in the diagram and my wire has a butt-connector no filter. What is the filter? An inline cap? Resistor?

    Doesn’t go straight, left to right back and forth at idle?

    Alrighty good to know. Yeah I use to try to over come it with constant inputs, but eventually they realize that it does kind of go in a direct path. 🍻Thanks

    Doesn’t go straight, left to right back and forth at idle?

    So when I’m cruising around the canals at /no wake speed. The boat seems to hunt left to right constantly with no input at the steering. It more or less goes straight, but it’s like back-and-forth back-and-forth back-and-forth. I uploaded a video, but it is not quite as apparent with just me on...

    3.0 popping ignition fuses, coil?

    The efi has its own harness with relay and fuses. It’s connected directly to the battery. Then it has a 12v signal wire to power up the computer. I actually used the choke wire for that job. The signal wire is small like 22ga or 24ga it would have evaporated if that was the problem child. I’ll...

    3.0 popping ignition fuses, coil?

    Had a group out in the water and was underway at 75% power for like 15-20min and the boat just shuts off. Found the ignition fuse (#2 on sea ray 180) blown. Think it was a 15amp? Took me a few minutes to figure out that’s what it was, I installed a sniper efi recently so I thought that was it...

    Serial number not correlating. What timing to use? Choke on power wire?

    Lastly is the module (77-8M6008208) in the distributor Mercruiser specific? Or will just a quality GM replacement suffice?

    Serial number not correlating. What timing to use? Choke on power wire?

    Thanks gents. The flame arrestor is still there but looks like it arrested a big flame at some point in its life and the sticker is cooked. I ordered a nos #19 wire harness. Per Holley: United States Coast Guard Approved Certified to ISO 8846, SAE J1171 Requirements

    Serial number not correlating. What timing to use? Choke on power wire?

    I just got done installing a sniper efi on my 3.0l. Want to double triple check I have the timing dialed in. According to the book there are one of three to use. The trouble is I can figure out what my serial number translates to. It M023026 and that is nothing like the ranges listed. Also I...

    Replacing shift cable. What are these parts for?

    I just got a GLM21450 shift cable kit and I’m a little unsure what these parts are for. The plastic watcher the little metal wire and the orange plastic piece.

    At wits end Runs great for 20miles then knocking then sputtering 3.0

    I’ll check the choke but I didn’t figure it running rich would lead to the pinging/knocking and coughing.

    At wits end Runs great for 20miles then knocking then sputtering 3.0

    The boat is a 2001 I believe the the 3.0 is considered a ‘98 model year? It has the electronic type distributor. I’ve also swapped the ignition module in the bottom of distributor and the pickup coil. I’ve set the timing per the book. “Disconnect the carb, jump the two wires on the...

    At wits end Runs great for 20miles then knocking then sputtering 3.0

    Finally got some time to get the boat in the garage. This was an issue before I added the new parts they were attempts to remedy it. Compression test came back at 155/150/145/150. Oil level is good and looks good not a hint of water. Attached is a photo of the plugs. Im guessing it was getting...
