In the absense of a wiring diagram, follow the wires - In the older engines they usually used starter solenoids for the PT, one for "up" one for "down" with a cat's cradle of wires between them. The third one , unsurprisingly is the starter solenoid. Newer PT units have 2 wires that essentially swap polarity to reverse the motor, and are fed through a single "two way centre off" relay.
You're looking for the two that don't have a chunky wire going to the starter motor.
Now the fun bit. If you have three solenoids, from memory threre will be three wires form the motor - blue, green & black. Black is the common, so attatch the black lead of your meter to it. Only one of the other two should see voltage at any one time. If it's not going up or down (And assuming the motor is OK) there's a high chance either the black wire will have fallen off or there is no power going to the solenoids in the first place. Also check the "small" wires to the switch. If the common has fallen off there (or corrosion in the bullet connectors in the remotes) that will kill it too.
I hope that description hasn't just confused matters - I just realised I used "solenoid" & "relay" to describe the same electrical lump. Wire colouurs are form memory based on my old Yam, so if I failed the memory test, Google "Yamaha outboard wiring colours" for the definitive list.
And yes. the release valve is down near the bottom of your clamp bracket, you'll need a long-ish handled big flat screwdriver.
