Hey guys, I have a 150 mercury on my late grandfathers boat....I have always been an OMC guy, so this thing is completely foreign to me. I winterized it at the end of the season and went to start it today. Was looking forward to putting it in the water, after cleaning it for 6 hours. Went to start it and she popped, I went to idle it down and she died. Went to crank it again and the battery was low. It tested good a week ago, when I charged it (Used a load tester to test) and I saw that it was about 7 years old. Went out and bought a new one. Put it in and she cranks very well but wont start. I now have no spark, as near as i can tell. Does anyone know how to trouble shoot this thing? I belong to a decent boating forum but there is so much posted its impossible to check. I hope someone here knows something....thanks in advance...
