Trouble shot it some more last night and 99% sure it is the module. Factory manual had a pretty good section and you set Hall Effect between two teeth and check voltage on both side of coil. With module hooked up low voltage on neg side, unhook module and goes to +12V. Manuals says that means module is shorted inside (makes sense).

So I removed it from dist. and the potting material on bottom side is cracked, I bet moister got into it. New one is on the way, should be here Tuesday or Wednesday.

Bought the new module and arrived today via UPS and I installed it tonight after work. Boat fired right up and runs fine on hose, going to sea trial tomorrow after work. I did check the ohm readings of my new high output MSD Master Blaster coil. The primary side is inline with factory coil (1.5-->2.0 ohm) but the secondary side is about 5k and factory specs are 9-10k. Hopefully the new coil is compatible with my ignition.

Update: Sea trailed it last night. Ran it around for about an hour and half, ran good whole time. Power was back, no low speed misses etc. :-)

Bring on the weekend.

you have to be carefull as some coils and ignitions don't mix...Rob

most blaster coils are oil filled and should be mounted in the vertical position. the msd high vibration coil is epoxy filled and can be mounted in any orientation

I have the coil mounted vertically so good to go there. I wonder how I can determine if my coil is compatible. I would think the primary side resistance is most important to the rest since it is weird to the module but???????????

Called MSD, either I got a guy that was having a case of the Fridays or their customer service suks. He wouldn't tell me anything. Answered like he was totally reading from script. Eventully I asked him if I was understanding ignition theory is that as long as the primary side resistance is same I cant hurt module and he said "yes...in theory, but he is still not sure my new coil is OK". WTF.
