Re: more 65 merc problems

You have one of two problems. The starter needs repair, or there is a voltage supply problem. Do the following voltage test while cranking. If the voltage reads greater than 9.5 volts, and it don't start properly, the starter is in need of attention. If it reads less than 9 volts, there is a supply problem (battery, cables, connections)<br /><br />*you must do this test if you want to be sure. Everything else is just guessing.....<br /><br />
