Northwest Fishing Reports

Looking for a mechanic to tune up a 1983 Mercury 40 horse in the tri-cities area. I'd like to find someone who is independent but a marine dealer will work also. I've looked on craigslist and asked co-workers and there doesn't seem to be anyone who does outboard work on the side??? Strange in an area with as many boats as there are in the tri-cities??? Motor runs great but I am going to sell the boat and I want it serviced / impeller / lower unit oil changed before I sell it so the new owner will have as much confidence as buying a 36 year old outboard can come with.

I'm new to the area and have no idea who to contact. Thanks in advance!
