Thanks for that Miker, any ideas who I get to those sensors?

Your water prob is under the battery in the bulkhead where it is placed. there is a drain off below it which goes to the bulk head below exiting roughly in line where the gear linkage is, (you will find a rubber flap). remove battery, clean hole, prob solved.
