Need some info.

I have a '91 force outboard 5h.p. and need to know the proper spark plug for this motor. Any help will be appreciated. Thanks..Mike

Thanks for the reply Bill. I did find the operator's manual for this motor and it called for a Champion L78C that crosses to an NGK B7HS. The plug you gave me is the same as I got from an old Force dealer. Since this motor is 17yrs. old could the numbers have changed? Thanks...Mike

Re: Need some info.

If your manual calls for L78C then that's what I would use. I looked up your motor here: http://www.ngksparkplugs.com/apps/watercraft/make.asp?table=toutboard
