I replaced the starter selenoid on my speedster and when I plug it in, it runs the starter. Nice thing about having 2 engines. If I plug it into the other selenoid, it does the same thing. I believe that it would be a relay causing the problem, but I can't seem to be able to locate it. Any thoughts. I had this boat for about 5 years and have been able to troubleshoot on my own, but need help with this. Love it, fun to drive.

your description does not indicate the problem.
Okay, The port engine would not turn over when I pushed the start button. I moved the stater wire to the starboard selenoid and it started, assumed that the problem was the selenoid on the port motor. I replaced the selenoid and now when I plug in the wiring harness, it turns over. It is not the switch. I assume that there is a relay between the start switch and the selenoid. I cannot locate that relay.

1995 Speedster Wiring Diagram
here is the wiring diagram for the 95....i am assuming it is somewhat similar. the switch goes through the mpem then back out to control the solenoid. broken wire?

you are sure it is not the switch? the switch could be jammed in the closed position sending constant power to the solenoid

exciting......so....i guess the options are:
1. there is a short in the wires going to the start/stop switch closing the circuit.
2. there is a short in the wires going to the solenoid sending power on the hot wire.
3. something in the mpem sending power down to the solenoid.
4. bad solenoid.
did i miss anything?

Lol, I find it depressing. I'll go with 1 or 3. I think I will try cutting the wires coming from the switch, near the mpem. That should tell me if there is a short coming from the switch wires. The wires from the mpem to the selenoid are short, so I would be able to see if it is shorted. I hate to cut, but if that what it takes. If course it is raining again. I need a garage.

Just start cutting wires. Eventually the starter will stop. 
I tried both buttons. I unhooked the wires going into mpem and the wires going to the selenoid are still hot. So the wires coming out of mpem going to one engine works with the switch and the other constantly hot.
