I’m not the OP, I do not have idling problems. I was just contributing my experience on what fixed an idling issue for me in case it might be useful information for the OP.
Hi Jimmbo,
Year & motor: 1989 MCM 3.7LX
Tachometer: Not sure if it's accurate. It does increase with throttle but not very smoothly. It sticks and jumps a bit. I have what I feel like is a decent DMM and tried to verify with the RPM setting hooked to the coil - but it was waaaay off. Even less...
Hi Scott. I have a knock-off electronic pickup that I believe has the same circuit requirements as the ignitor 1. I had idle issues before learning that the sensor needs full 12V (but not over 12V). The way I had inherited the boat, the previous owner connected the resistor wire from the choke...
Got a 180 HP 3.7LX in the spring. First time on the lake I noticed 3 things that landed outside the range of what I would consider normal functioning or performance. 1) Overcharging, 2) poor warm idle (for example, cuts out when waiting in line at the dock), and 3) no WOT. The only remaining...
Nice. Feels good to check something off the fix list. I just got my first boat this past spring. It's a 1989 3.7LX Mercruiser, so probably very similar--if not the same--as your stock charging setup. I too went with breezeworks and had no issues. Great kit!
If you wouldn't mind humoring my...
Hi EZ. Have you seen this list yet? It's in the adults only section. I also have to troubleshoot a WOT issue with my boat (although the symptoms seem a little different than yours), and I intend to go through that list of 15 and test every one before letting myself get carried away and...
Thanks bondo. The boat was run about 2 hours prior to this. Sure, I guess it makes sense that the anti-siphon would also function to keep fuel in the line. I guess I was just curious if under normal conditions a fuel pump would be expected to create a seal that prevents fuel from draining back...
Hi forum members. First boat. First post.
Picked up a 1989 20' Stingray cuddy this year. I have two little boys and I thought it would be fun to get something that we could putt around the lake in on nice summer days. We've been having a blast and actually that old 3.7LX Mercruiser has far...
