Help with my 89 Suzuki

[Guest]

This may sound like a dumb question. But I just bought a new (used) boat that has a 89 25 horse Suzuki outboard on it. The seller did not supply a manual for the motor. I have run a few outboards in my life but never a Suzuki and I cannot figure out how to get the electric start to engage. It looks like there is a red colored cap on the right side of the motor that fits over a rubber button that needs to turn somehow. Is this the starter? And if so how does this mechanism work? Also there is a dial guage located next to it with an s and and f on it. What is this for? Thanks for the help.

Zesty,
Not sure about the starter......but the dial sounds like an idle adjustment (s=slow, f=fast)
