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!
