Toss that belt on and see what she does. It sounds like you have a I/O engine. Motor looks like a car motor...right ??, even though I thought a sea drive was one of those large brackets that the motor sits on.
If it is a I/O engine. The center pully would be the crank shaft and the second pully would be on the front of the power steering box. But you mentioned the helm is where you added fluid. Snap a few pictures and post them. Somebody will know for sure.
