1992 40HP Outboard Stator replacement help

[jstiene]

Hello. According to the local engine repair shop back in fall, I was told that my stator needs to be replaced, and I would like to try doing it myself. I dont recall if I need to purchase a black or red one (one replaces the other I was told). Has anyone done this replacement and is it very simple, and which color stator do I need to order? Also, any special tools that you might suggest?

Any help would be appreciated.
Thanks
Joe

What is your engine s/n and do you have the service manual which will show you how to test the stator and change it if necessary?

The problem is that the engine runs bogged down, usually only about 50-60% of full throttle even when open all the way. Then while under way it will sputter and kick wide open and run fine. Then next time I start under way again, same story. Local marina tested the stator and said the ohms reading was off. They also said there was a technical bulletin on my motor that required a replacement of a different color.

There is a reason I asked for the engine s/n but that is up to you when you are ready.

That s/n comes up as:

MERCURY - ( 40 H.P. (1992 ))
Serial No: 0D129002 Model No: 1040412MD

Parts and Service Bulletin list for s/n 0D129002:

Search Results - Crowley Marine

Don't see any bulletins applicable to your engine re stator.

The service manual you require is P/N: 90-814676R1. If you do not have this manual, see my message to you in Notifications at the top of this page.

The stator, seen as item 4 under FLYWHEEL, STATOR AND STARTER MOTOR in the parts list is selected by s/n and whether you have electric or manual start. If yours is electric start, the one you need is 832075A20 STATOR KIT-4 CYL or 832074A6 STATOR KIT if manual start.

I would test the stator yourself before replacing it, I wouldn't just take your shop's word for it. You will also need a mercury flywheel puller to get it off. DO NOT try to use a regular flywheel puller unless you want to buy a new flywheel too. The flywheel pullers can be found in a lot of different places and are worth every penny. But do a complete ignition test from the manual first, before you go throwing parts at it because someone said it was bad. my 2 cents

Hello. I am finally getting to replacing the stator and I need to order the Mercury Flywheel puller. Is there only one that is standard for all motors or is there a specific part number of the puller for my older model engine?

Hi. So I am at the point where I am trying to remove the flywheel to get to the stator. I have removed the center bolt and attached the flywheel puller but cannot see, to remove the flywheel. I was wondering if anyone had any suggestion on how to remove it. I believe as I tighten the center screw on the puller, that it should pop the flywheel loose, but no luck. Am I supposed to be tapping it with a hammer, and if so where?

Any advice would be greatly appreciated.
Thanks!
