"Hello,
My 1991 40 Horse Merc


"Hello,
My 1991 40 Horse Merc will only spark on the bottom two plugs. The motor looks like new and is always stored in a boathouse. We only use it once in a while. We did run it last weekend without a problem. What do you think could be the problem?
I look forward to your reply.
