At the lake need help

Here's the senerio
We were skiing and all was fine. After setting up for the next skier I started the boat and bumped it into gear to take up slack when I accidentally knocked the safety switch lanyard off and killed the engine. I stuck the lanyard back on but then no start.
I have power to the starter but all it does is make a rapid clicking sound. It definetly sounds like the clicking is coming from the starter.
Volts are good just clicks. Never had a problem with this one, it's my '95 GT-40 EFI any ideas????

I'll double check them but had no problems on the six or so starts before I killed it.
Thanks

You were dead on Tim thanks. I decided to start at the source(battery) and work my way back to the starter.
I started the terminals they were tight and clean. Re-attached still just clicking. Then I checked the two red power wires that are bolted to the positive battery clamp. Found them to be a little rusty/dirty cleaned them reattached and BINGO fired right up.
Must have picked up just enough corrosion/moisture to lower the voltage to the starter relay.

Vacation saved(all though I do have the '85 with us) Thanks to CCFAN again!!!!
