Electronic ignition for Mercruiser 170 (1985)?

We, my brother and I own an 87 V20 and we just had the ignition upgraded to an electronic unit. Do not know what brand, but we were assured a faster starting engine and slower trolling speed as we would be able to idle the engine down much lower than before. Haven't had it on the water yet, but we are expecting good things. Make the change, I'm sure you will be pleased. Have a safe boating season!

Thanks for all the great replies - I'm hoping this boating season will be a little LESS safe for the fish swiming near my V than last year:). I'll post progress and results.

I installed the Petronix ignition last year and for the money, it was one of the best upgrades I did. Super fast starts and smooth running. I cannot comment on fuel economy because I did not take a baseline prior to the installation but I am sure I am doing better than points.

I picked up the rebuilt distributor with Pertronix kit in it and Flame Thrower coil today. The old shaft was gauled badly and I can only imagine how bad the bushings were worn - no more side play and I'm pawing the ground to get the new stuff installed. Hopefully this weekend - we'll see if work cuts me a little slack.

Well, no continuity in my existing wires - planning to get some bulk MSD spiral core wire and make up a set. Any comments or warnings before I order the wire? Also, on a boat the size of a V-20 is there a requirement that the wire be USCG approved? MSD sold their marine business, but says there's no difference in the insulation on the marine and the automotive product.
