DOT 3 or DOT 4 is what should be used in your boat trailer. DOT 5 cannot be used in trailer brake systems unless stated explicitly by the actuator and brake manufacturer. This type of hydraulic oil does not absorb water, and the silicone in the DOT 5 makes the seals swell and can bind up caliper pistons.
