spark plugs mercury 55 seapro (1999)

[tomasvg]

God day,<br /><br />I have purchase a Mercury 55 MLL 2 stroke model (serial number 0G819744)<br />and it was equiped with NGK 4838 BP8H-N-10 spark plugs.<br /><br />I try to buy new spark plugs but I don´t find this model. The only model I<br />can purchase in local market is CHAMPION 936M L78YC.<br /><br />Can you tell if this model works with my outboard engine.<br /><br />Many thanks and regards<br /><br />Tomás van Gelderen<br />Buenos Aires - Argentina

I would stay with the spark plug the manufacture has suggested.

See if they have NGK BP6HS. That crosses to a L87YC. <br /><br /> Cross Reference
