Go to www.championsparkplugs.com and look up your engine.
I would recommend you use the Bosh Platinum plugs. Save you from having to
change them for several years - probably never have to change them again.

As for the oil - you are supposed to use straight 30 weight oil. If you
want to use synthetic - I would use 10w30 Mobile 1.

As for the filter - go to
http://www.mercurypartsexpress.com/P...phome.asp?CID=
and enter the serial number of the engine. You can look up the filter and
then use the fram cross reference to hopefully find the number.

So I'm about to climb up in the boat and check the number on the oil
filter and plugs. I'm going to change the oil and filter, fuel filter,
and plugs. The lady I bought the boat from had a zippered case full of
SeaRay paraphenalia, but nowere in there does it advise plug or filter
number. It's a 4.3 L normally aspirated v6 chevy.
Any ideas on the plugs and filters? Don't say Mercury, because there
ain't no such dealer for miles around. I'm thinking Fram filters and
Autolite plugs.
Speaking of plugs, anybody have anything good to say about the
"Splitfire" version of Autolite plug?
Then there is oil. With all the ratings and such, I'm thinking about
using a 15w50 Synthetic. Any experiences with that I should know about?
Again, no mercury dealer around. If anyone thinks it's workth it, I can
order the stuff, but normally these brand names are just ways to make
money on maintenance supplies.
Lastly, there is the air filter. Kind of strange looking as airfilters
go. Could there be a Fram replacement for that as well?
Thanks,
Al
