That one says it only does 2 or 4 cylinder models.

A few years back I ordered a tool from this guy.

Chris, I believe it says 2 or 4 cycle (not cylinders)
Anyway, I was just wondering if anybody had any knowledge of it or maybe knew of one they used and trusted.

I went to the link you mentioned... nice stuff.

I was in Fort Collins, CO. one time and watched this guy test a multiple cylinder engine with a spark tester that could check 8 cylinders at the same time. All the lead wires attached to this one device. ( I have wanted one ever since I started working more and more on Outboards) I only have a spark tester that will check 1 at a time, and I had a Tiny Tach until it broke, I reverted back to my Treysit Serometer (or Vibro-tach)

I just need more than that to feel accurate and more professional.

My bad, you're right on the tester - I read the specs wrong.

I thought the Mastertech guy had a similar tester to what you described, but the picture of the one he has isn't showing up.

The one he had (I thought) was like a flat bar and you hooked the lead wires on to each side of it. It then has a spot in the center which visually shows the spark of each lead. I'm not sure if that's the same style of tester you were looking for.

Even though this merc part number is no longer available from mercruiser, I think it would have been kind of like what you where looking for. (854009A1)

Below is a bunch of good links that could help you out someday.

Check out the Digital Contact Tachometer from harbor freight.
The Digital Photo Sensor Tachometer is kind of cool/Different, Just thought I would through that in there.:sssh:
