well I wouldnt advise running in salt water, but I do it sometimes. Your epoxy coat better be thick on the wood hull. Also the boat needs to be really sealed. Your going to need to rinse it off after every run. Your going to want a graupner or dumas prop, probably 3-blade. Titans run 14.4v's right? so youll need 12 cells, preferably gp3800's which you'll need to assemble, with battery bars.
