Testing mercury stator

Your outboard stator is the "powerhouse" of your outboards ignition system.

Testing my stator using a ohm meter my readings are. Between blue and red leads Also does the stator have to be installed on engine for this test and is this a good test procedure? If your readings are not within the range specified for your stator the part is bad. Replace it. I left out a little info on my 1st post, the numbers are from a new Mercury stator that I just got today to replace my old stator. My old stator numbers are

My starboard motor has had poor acceleration past 2,RPM for a few weeks. I had changed all filters, changed separators, changed spark plugs, cleaned final filter, ran alternate fuel tank, and still no solution. Each motor has two of these. Try swapping one from one motor to the other. If the trouble switches sides with the switch box, that is your problem. This is a very common failure. I suspect dirty injectors. If you find a dead hole, swap the coils over to the other engine all of them. If you have fire for each hole then I would have the injectors cleaned. There are drain hoses on each side of the bottom of the block in the bottom of the cowl, make sure they are there and not worn out or broken off, what was happening to me is water was coming up threw the holes from the bottom of the cowl and would short out the bottom 2 cylinders, When you dropped speed the water would not come up and the plugs would dry and fire again. If you look at a diagram you will see these short little drain hoses that I'm talking about.

Macsimus, My shop is baffled what the heck is wrong Search Advanced search…. Bruster, I got the ohm readings from Mercury Performance service manual pg.

Are you noticing anything wrong related to the battery and engine? Therefore, you must detect the signs of a bad stator. The most common signs of a bad stator in a Mercury outboard engine are problems with engine activation, lack of power, and misfiring. Getting panic attacks? Thus, you can overcome them in the future. Besides, the maintenance tips will let you keep your stator in better condition. With the assistance of rotating components, the required energy passes through stators. So if anything is wrong, fix it or go for a new mercury outboard stator. But how can you tell when you need a new stator? In general, a stator is liable to generate sparks and AC currents.

Your outboard stator is the "powerhouse" of your outboards ignition system. Most Mercury Outboard Stators perform two important functions 1. They provide voltage to your switchbox or CDM's. They charge your vessel's battery s. A faulty or failing stator can cause one or more symptoms.

Would often kick in to match it's twin but then would come back down. Click to expand I'm gonna check the lines later. This is the second recent article in which an owner of a Mercury outboard motor with a running problem that has an onset at an engine speed range of above 1,RPM has speculated that the cause is a malfunction of the stator. They provide voltage to your switchbox or CDM's. Can anyone confrim which part number is correct? That would be something for a phone conversation, however Do all 6. There are drain hoses on each side of the bottom of the block in the bottom of the cowl, make sure they are there and not worn out or broken off, what was happening to me is water was coming up threw the holes from the bottom of the cowl and would short out the bottom 2 cylinders, When you dropped speed the water would not come up and the plugs would dry and fire again. They talk about tools, how to use them and test procedures for each componet. The 3 cylinder 90 has only a red and a blue wire, not pairs of red and blue.

It was identical to the Mercury piece as far as I could tell, and even included the Mercury instruction manual, with Mercury's copyright info at the bottom. The engine mounted tank should fill. There are different readings for 90 and hp, 3 vs.

Results 1 to 18 of Ok so I started my diagnosis and found something interesting on my yellow leads on the stator. Good catch on the stator. Keep in mind that a bad stator might not be your only problem. See if the light pulses differ visually or stop completely on any of the cylinders. Otherwise, if you pull the lanyard from the safety lanyard switch the spark will usually be suppressed. This allows you to visually observe the spark. Since switch was funky anyway--it was sticky, even after spraying non conductive lube in hole--[the ignition switch was] replaced with new Mercury part. Cleaned out the screen with a toothbrush and all was well. Replace it. This would have to be what Mercury calls the "trigger". In my case, when the motor is cold it idles strong.. I've always wondered if they weren't a source for contention for problems BUT, on the other hand, they've been using them for years and I guess if a component was to act up, it will work on the weakest link to kinda put you onto the source of the problem. Electrical problems confound me and humble my ego quickly.
