No...and why.
Here's the difference between a freshwater and saltwater rigged boat.
Freshwater:
Painted steel trailer. Cancer victim when it is exposed to saltwater, no cure.
Bare copper wiring, simple butt connectors, unsealed switches, all will have degrees of corrosion, no matter how well you thought you washed it.
Carpet...it'll be a gonner.
Plastic windshields, with oxydized aluminum hardware, say goodbye.
I have had more than a few (actually a lot) of guys trying to trade in what should have been decent rigs a year after "one trip" in the brine. Trailers rusted from inside out, nothing electrical works, carpet frayed and gone...
If you're thinking about taking your toy to the coast one time, rent something, if it's going to be an on-going affair, get something built for it.
And...for the Louisiana/Mississippi guys, there's a big difference in your saltwater and other saltwater, yours is much less "salty" compared to South Florida, or South Texas, it does make a big difference.
Or just ignore this, and do what you want.
