part 2:

5- Get a 5 gallon pail of electrical motor cleaner...not spray cans...you want
to immerse the starter motor and solenoid in it,(after removing it safely from
circuit and from the engine). This will remove the oil and spooge that the
water deposited into the windings of the armature and the coil. Let the starter
and solenoid dry thoroughly and then check them for resistance from terminal to
ground and from terminal to terminal...if you read 0 ohms terminal to ground,
you're grounded, if you read 0 ohms terminal to terminal, you're shorted.

6- Disconnect your battery, and using a spray bottle, spray all of your wiring
terminals that got wet. wipe them down and let them dry thoroughly. Then start
reading resistances to ground and from positive battery cable on "downstream"
to above the high-water mark. Only if you have infinite or high resistance to
ground, and low resistance through the circuitry should you then attempt
energizing the circuit(s).

7- Sorry, to belabor the obvious, but find and fix the leak. Relying on your
bilge pump to keep afloat is not good seamanship. Such a craft is not
seaworthy...and as you will no doubt soon learn, fixing boats is expensive and
it sucks. Much cheaper and easier to prevent problems rather than repair them.

G'luck;
