I am having some problems with one of my 115hp 4-stroke engines. It seems that in a previous post I read someone had purchased the software for the 4-stroke yamaha. If so, could I possibly rent the software and any attachment cables ? It also seems that I remember a post of someone finding/using a mechanic from Guaymas that was knowledgable and trained in working on these engines. If my memory is correct, could someone please forward the name and contact information of the mechanic. Will be back in San Carlos mid-day Friday for ten days and don't want to miss any more of the fantastic fishing.
