Best plugs and manual for '93 Merc 20hp????

[Jamar]

Any recommendations.....am currently running NGK BP8HN10.....just picked up a new set of Champion equivalents..QL78YC. Should I swap them out and stick with the NGK or the champions just as good for this motor or what?<br />And about a service manual....any opinions? Should i pay 35 for a factory service manual or save my money and stick with the Clymer. Is one noticeably better for this year/model?<br />Thanks in advance for all the help guys.

I'd stick with the NGK's for the Merc and get a Factory Manual which will be well worth the dollars spent.<br /><br /> manuals
