I have a 98 mercruiser 3.0, lost fire and pulled the distributor out to change the pick up coil, put back together engine tdc rotor pointing towards one, bypassed the shift switch and hooked the distributor wires together to go to base timing and set it to 1degree btdc and disconnected everything and made sure the timing advances like it should, now boat idles fine and will rev up in neautral but won’t in gear in the water. Any ideas or can I just turn the distributor while in the water like a old school distributor??
