Re: Salt Water boat in Fresh Water
maybe, maybe not.
I don't see a silt line on the engines, or on the surrounding bulkhead. I see a lot of external corrosion but can't say it's killer. that can come from electrolysis when the batteries short out, or being left on in wet conditions, etc. Not the best looking motor, granted.
obviously the holes in the hull have to be fixed but all that occurred while the boat was banging around. Unless the boat was submerged above the holes and sat there for days, no significant water would get into the inside to cause big problems.
the dirt on the upper decks is dirt. not silt from being under water (look at the condition of the berths, etc. below). Looks just like my boat's decks after Irene (and it stayed on the trailer). No problem there.
If it was stored plug out, whatever water got in, got out.
But here is where I have concern: what is the effect on the outdrives, probably stored down, and the transom where they attach, from the full weight of the boat sitting on them? How about banging and dragging around on the pavement while the boats played bumper cars?
I'm going to split the difference between the OP and Taz. There could be big issues in the motor and transom/drives, but just as likely not, especially as to the motors. it's not a boat that sat underwater to the helm for weeks. But it warrants an inspection before committing.
Or what is the difference between that used boat, undamaged, at retail compared to $14,000 + shipping + new engine blocks + outdrives + transom structural repair+ hull and swim platform repair? That's your best case v worst case.
