Hi, A neighbor has a 9.9 Yamaha that has been sitting in his garage for
about 15 years. Not sure how well it was stored or fogged or conditioned or
what. He has been watching me struggle with all my stuff and now wants to
get his 9.9 running again. Any suggestions as to what we should be
replaceing or servicing on the engine? Looks like about a 85 or 88. We have
serial number and model numbers so can buy the kits online.

What service procedures should be done on an engine that sat in a garage for
this long? Impeller for sure, the carb kit replacement was easy but is that
necessary? I suppose get it running first and flush it completely etc etc,
grease, lubes. Anything else you guys can think of? Thanks again.
