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.

Probably change the impeller, take the carb apart and be sure that it
is clean and all the passages are open, change the spark plug, check
that everything moves freely and is lubed, Check that there is a good
strong spark, check that the shift is adjusted correctly.

Or being the lazy cuss that I am, maybe just put some gas in it and
pull the handle :-)
Cheers,
Bruce
