What is your replacement radio? Didn't your new one come with an owner's manual? What boat is it going into and do you have separate amps, etc?

Usually red is to keyswitch (make sure fused if your radio doesn't have one), yellow is memory and needs constant battery, obviously black is ground. Blue would be remote turn on for amps etc. You should have a handful of colors matched with colors that are black striped. This is all assuming they side cut the wires of the old stereo and some remain. If that is not true (disconnect battery) you should be able to use a mutlimeter and "ohm out" the different speaker wires. Black can be checked back to the negative battery cable or engine block ground. (connect battery) Yellow would be 12V positive all the time and red 12V positive with the keyswitch.
