Tower Speakrs on an Outboard?

[soundwakeboarder]

Hey I wakeboard in salt water and need an outboard to tilt out of the water. I'm really looking forward to getting some tower speakers but I'm not sure if they'll be able to be heard over the outboard.

First of all, is an outboard any louder?

Has anyone had any luck with getting speakers heard on an outboard and if so, how powerful were they?

Any insight would be great, thanks. This forum is awesome!
