Needing to decision if to go forward with repair/renovation? It is a 1994 24’ Grady White Explorer with a 5.7 liter I/O on it. The engine and stern drive was replaced in 2014 ($28,000). I am confident the engine and stern drive has less than 50 hours on it. I know the former owner. He kept it in immaculate condition prior to the storm. It was damaged in the September storm while in a covered lift. It got partially submerged (salt water) at the port side stern. The bow rail and wind shield (to be replaced, no cost for part) were damaged.
Appearances indicate a battery, power tilt/trim system and battery switch got submerged. The bottom/rear of the engine also appears to have signs of being wet (rust). All occurred in 9/19 (Dorian). No remedial work was done until 30 days ago when I purchased it. Since then I have done some cleaning/flushing in the deck under area (stern, port side). The boat itself has a token amount of repair work needed.
My concern is the mechanical areas that got wet, especially the bottom, rear of the engine, power trim/tilt system and battery switch? What can I do to eliminate/minimize future corrosion/rusting especially the back/bottom of engine given it has sat for almost a year? Should the electrical as to the trim/tilt switch be replaced? I am replacing the battery switch.
I am having my friend and trusted auto mechanic inspect the mechanical. Plans are to get it cranked and running. No electrical is working. I suspect due to the battery switch issue. I have no reason not to believe that all the mechanical is functional?
Any thought on the issues are appreciated?
