The MoTeC dealer that I bought my M820 from recomeended the LSx coils and thus far I have had zero problems with them. His rec came from using them on T-BIGMF'ers gulping meth and putting down damn near 1000hp. However, you need to be sure that whatever EMS you decide to run does not need wasted spark. The LSx coils require more dwell time than is allowed and like a healthy supply of juice.

As for the Mercury Marine coils............. being a MARINE GUY myself I can tell you there are two types, the I/O type and the outboard type. The I/O types are standard LS coils of some variety. The outboard coils I have seen two versions of, the 2-stroke and the 4-stroke. I would think the 4-stroke coils would be require to long of a dwell time and produce an average spark. The 2-stroke variants, well, obviously they have to be a much stouter coil.

FYI - Yamaha builds a number of Merc engines. Best thing to do would be to contact Quicksilver directly and talk to them.

EDIT- QuickSilver being the parts division of Mercuy Marine... get it. QuickSilver, Mercury
