Any thoughts on brands and types of sparkplugs? I want to pick up a spare set for my '94 Merc 90. The engine currently has NGK BUHW-2, surface discharge (no gap), plugs. I have seen SplitFires advertised in several catalogs. Are these any good? If I get them any idea where to get specs on how to gap them. I couldn't find anything in the Merc manual.

Barry, Mess with the spark plugs if you must BUT realize that you will not gain anything from changing from the factory recommended plugs, and it is likely to cost you real $$$$$ when you get done. Before you even remotely consider using Splitfires go to the forum at www.boatdoctor.com and read the current posting there on Splitfire plugs for marine usage or any 2-cycle usage for that matter. JUst my opinion but a kinda strong one. Dave

If Splitfires were the miracle plugs that they, Splitfire, claims them to be every engine mfr would be installing them at the factory. I read some independent dyno tests on a Harley and they actually decreased performance. Stay with the factory recommended brand and part number,
unless you need a resistor plug to eliminate EMI / RFI that causes your electronics to go haywire. I've used Champion SS Marine plugs successfully to combat this problem. Don

I second that if Splitfires were a miracle
plug, they'd come from the factory. Those
who claim a big performance boost have
probably replaced an old dead or fouled
set of plugs with new ones. The same thing
would have happened with any decent plug.
