noah's flood
I agree with Peggy, you must tend to the engine first in order to save it from internal corrosion - meaning you must purge the water from the internal parts/spaces of the motor asap or you will wind up with a spare mooring anchor. There are plenty of resources in terms of mags and books about how to deal with a waterlogged diesel. You may have to jerry-rig wiring to get this done. Speaking of wiring. Mostly bad news. If and only IF your electronics were not on - not being supplied power in any way, shape, or form (including no internal back up memory batteries and so forth) - there is a chance that after they completely dry they will still work. The key there is completely dry. If you put power to waterlogged instraments, they will fry instantly to state the obvious. If your boat was in salt water when it flooded, I would remove and soak (meaning immerse in a bucket) your instraments in fresh water for awhile (remove any batteries first), frequently replacing the fresh water so as to completely purge salt residue. Then let them dry for as long as it takes. After that, if you can get at the innards of the gear, I would use a water dispersing electronic parts cleaner and douse the parts inside each instrament. Note some electronics can't tolerate water at all. The above is a lot of work, and it may not bear any fruit. You have a shot at salvaging your electronics if you do this quickly. If your boat was awash for a long period, this gear may be a lost cause. The electrical wiring in your boat may not be ruined per se, but you will see the wiring corrode out very fast if water leached into the insulation, which it probably did. My vote would be to re-wire the entire boat - it's a safety thing. I hope, as the others have indicated, that your boat is insured. If you are determined to hang on to it, you are going spend big bucks making it well again.Like Peggy, I am curious as to what happened to cause the flood. Either way good luck with it.Mike
