I have 91' 50 hp, and it calls for BU8H. BUHW are for 75-115 HP according to the manual. Don't know if the year maks a difference. I have a Clymer manual that is worth the few $$ it costs. I have saved thousands of $$ on repairs(kidding), but I know a lot more about my motor than before.<br /><br />Jerry

BUHW and BUHW-2 spark plugs are 'surface gap' plugs.<br /><br />The difference between BUHW and BUHW-2 are that the BUHW are 60 thou gap and the BUWH-2 are 80 thou.<br /><br />Chris...........

Go to the NGK site and see. My 1980 50 uses BUWH-2 but later models are just BUWH. They are surface gap and look almost identical.<br />I reckon Rick is right AGAIN...<br /><br /> http://www.ngk.com/results_appOther.asp?otherMotiveID=23950&mfid=1

Andy,<br /><br />Correct, they look almost identical. The difference is just 1/2mm.<br /><br />Chris........
