Trying to figure out what my problem may be.oil in water and the rear spark plug is fouled with rust colored deposits. Other plugs look fine . Mercruiser 130 4 cylinder. Bad manifold, blown headgasket or cracked block
bayliner igniton fuse
bayliner 3.0 gm carb will idle and troll all day but at mid,full throttle every 5 minutes we fill slight miss moments later blown ignition fuse. Did the same thing two years on one day only and now shows back up but only worse
