have a bunch of questions on a 86 70hp evinrude

[cparker072]

the 1 motor runs good for like 15 mins then starts reving really high for a min then goes back down while in gear, what causes that? Next question other engine Idles great starts right up revs up nicely then when put in gear shuts off my brother in laws neighbor "mechanic" says its the stator and wants to charge him 6-700 to replace it im thinking its the fuel jets what do you guys think?

Stay away from your brother in law neighbor "mechanic". You'll get a lot better info right on here.

Is this in the water or on the trailer? I would check the mechanical advance timer base and timing first, followed by a good sync/link. Before BIL(L) touches it make sure your working on a good motor. Their is no magic to these ignition system except for their simplicity.

As stated, there are many simple things that it could be before you go buying a new stator. Ill assume you do not have a service manual? That would be my first investment. Go to outboardbooks.com for a factory reprint, or ebay for a used version. Get a factory OEM Service Manual, not a Clymers or Seloc, especially for Linc n Sync procedures. This mechanic is trying to say that both stators bit the bullet at the same time? Highly unlikely Id imagine.

I would follow Jeffersons advice first, after you buy a manual.
