I have a 1990 Force 120 L-drive in a Bayliner. I have had nothing but problems with this boat, here is the latest. I just put on a new exhuast and head gasket as it was taking water into the cylinder. It started fine once I fixed this and then I took it on the river, cruising along at 40 mph for about 5 minutes when the boat just dies. There was no sputter or nothing, it died in an instant. So after getting pulled back to dock by a fellow boater, I took her home and discovered I am getting no spark to cylinders 2/3/4. One good thing, there was no water in the cylinders (LOL). I ran down every wire and balanced it off the wiring diagram as well, all was fine. Any ideas on why I lost my spark so quickly? Anyone know of a boat mechanic in the Louisville, KY area that works on these L-drives. Every boat dealer around here runs when I tell them what kind of engine I have and then they say sell it as fast as you can.
