Re: mercury 40 hp. 4 stroke

If it was me and I spent all that money without the issue being resolved I'd call Merury Marine directly and ask for a call back from their regional rep.

I would think he could point you to a local tech who is known to be better than the rest.

I've asked many Mercury related questions on this forum in the past and found it's just not very active when it comes to Mercs. The knowledgable members here are great with Johnson and Evinrude issues. There is a Tohatsu guy "Tohatsu Guru" here that is very knowledgeable and since many Mercs are actually made by Tohatsu he may have an answer for you.

If he doesn't chime in here . . . post this same question over in the Tohatsu forum for him to see.
