    94 merc, 25hp, ignition issue

    I bought a 94 merc that needed a switch box/power pack/brain. Anyway, I bought a used one and connected it properly using the manual, and when I pull it over, I get a spark, but not with each stroke, but after the end of the pull. I figure it's a grounding issue, because if your hand or foot is...

    I had heard of this and am about to replace my leaf springs, so I'm wondering the pros and cons. Some of the other fisherman in my area have mounted their axles on the top, not the bottom of their leaf springs. I hear the advantage is it lowers the trailer and makes launching in shallow water...
