[hero]

Hope somebody can help,sometimes the key will turn oevr the motor,sometimes no response(always at the wrong time).Have had solenoid,starter motor checked and the problem never happens when mechanic is checking.Boat starts fine a few times, then when stopped for a while,no response from key,continual trying results in finally working, what is this problem for gods sake, it is driving me insane???

hero,<br /><br />No response at all? Or, nothing you can hear?<br /><br />First off, remove and clean every connection under the cowl. Pay special attention to the negative lead on the engine block. Don't just look at it, remove it and clean it.

I have seen on numerous occasions auto starters<br />that have a dead spot , if it happens to stop<br />in just the right (or wrong ) spot it will not<br />function. Not sure if this can happen on this starter but may be worth considering. When this<br />has happened to me a quick rap from a rubber mallet will sometimes jog it just enough to start.

Hero have you checked the switch itself. If your set up is like mine the key is in the control box. Here are the steps if it is. You will need a test light or meter. <br /><br />1. disconnect battery<br />2. key in off postion. connect test light/meter between Batt and A terminal.Should not show continuity<br />3. Key on light should show continuity<br />4.key to start position. should show continuity<br />5.key held in start position.transfer from a to S should have continuity.<br />6.transfer leads to m terminals. should NOT have continuity in start and on position.<br />7.Off position should show continuity.<br />8.transfer to b and c terminal. key on position and push key in. should show continuity<br />9.turn key to start and push in. should show contiunity with key in.<br /><br />May not be your switch but just a thought.

Follow DJ and Richards advise. Also check neutral safety switch in control box.
