So i have one of these rafts

and it has a trolling motor mount.
This is the motor they recommend i think

I read that the motor is not for saltwater. What happens if i do use it in saltwater?
What other brands offer a smaller trolling motor similar like this that is okay for saltwater?
Also do you think this raft is big enough to patrol calm areas of NPH and Alamitos bay with 2 people?

THanks,
Ryan
