I know this will start a maelstrom of responses. I am interested in recommendations to replace my MSD 6M. I am looking at replacing just the box not the whole system. I have the MSD distributor setup with a custom advance bushing that gives me more initial timing for a better idle and I have the HVC-2 coil. I am considering Mallory or Crane with the built in rev limiters. I've had to replace my 6M once already and I haven't heard anything good about them so I want to get a backup unit before the season starts.

I have the 6ML-2 blue msd box with rev limiter.. No problems..My timing is locked in at 34 degrees idle no advance

What compression are you running? I tried the MSD start delay box with a locked distributor but the box screwed up my ignition so bad I had to remove it. I was thinking of trying to lock it at 34 but was afraid of toasting the starter. I have a 524 at 10:1 compression, although I have a pretty big cam, to bleed off pressure while starting. I haven't checked to see what my cranking pressure is.

i'd go w/ the crane.worked well for many years and still going.just picked up 2 for my own boat.

The Crane is this same thing as Daytona. Daytona has improved the box from what Crane had years back. The engineer at Daytona, designed the box for Crane back then. Yes is a excellent piece.

The Daytona Sensors CD-1 Marine box is certified and comes with the coil. Call Bob Madara, I supply his for since I am WD he is a dealer for me.

I have two of these, new in the boxes, sitting on the shelf that I was going to use on a project that is never going to happen. Let me know if your interested, and I can get them shipped out ASAP.

I have Twin 509 ci.. 9.1 compression- (2) 1000 amp cranking starting batteries set on both on the Bat switch.According to Nickerson performance at 9.1 compression if I had starter lag then it is a battery or a cable...
