Are you mechanically inclined at all or nah? I ask because I was able to get the factory service manual for my Johnson 90HP online and then use Crowley Marine online to find all of the correct parts I need. I came to find that the local boat mechanics were hit or miss for me, but I am almost anal-retentive with using factory parts and specs for everything. The most competent guy I talked to was at The BoatHouse in Athens, AL, and at Lawrenceburg Marine in TN.
