Author Topic:   Mercury Stator Installation

I have an 1987 Mercury 115 out of which my far more technically oriented friend pulled the stator. (He's an electrical engineer, he knows his stuff.) I have the new one and would like to try to install it myself. Naturally, I have no service manual.

Is it easy enough to do?

Is there anyplace where you can download a service manual pdf either for free or for fee? It looks simple enough, but I would feel more comfortable staring at pretty pictures and having some text to follow to do it correctly.

It is easy enough to do, but for $20 or $30, do yourself a favor and please buy a manual. I bought mine on an auction web site. You'll learn a lot about your motor and it will pay for itself down the road.

I just changed the stator on my 1995 Mercury 125. You need a flywheel puller, but if your friend already removed the old one, then that's taken care of. Orientation is critical, so hopefully you saw where the old one was positioned before it was removed. Otherwise it is a simple plug in deal. Be sure to use Locktight (sp?) on the stator screws and flywheel nut. This is very important.

Confirm the old one is bad by using an ohmmeter between the winding and its ground. On mine there is both a low speed and high speed winding. The positive and negative, or ground, side of the winding are the same color wires, where one of the two has a black stripe. If you get no ohm reading at all, the winding is open, or broken, and it is indeed bad.

Hope that helps,

John

[Sought advice on diagnosis of an engine problem, but this topic was already begun in a separate discussion, so it has been removed here.]
