Spark plug for 1977 Mercruiser 165

[twh67]

The service manual for my MerCruiser 165 calls for a Champion RBL-8 spark plug. To the best I can tell champion does not make these anymore under that number. The manual does have a AC part number of MR43T. Does anyone have a champion equivilent to the RBL-8? I can't find a cross refrence<br /><br />Thanks

My boat manual says that my engine will take AC-M43T or Champion RV8C.

MR43T is a good # for a good plug....
