Gaffrig GPS speedo install help

I am installing a Gaffrig Analog GPS speedo on my '90 Checkmate Pulse 211,
My question is: What are my options for mounting the antenna? Obviously it needs a clear view of the sky, but can it be mounted sideways in the motor well? I'm assuming not, but it is kind of big and I don't want to kill the lines of the boat.
Any help would be appreciated... Thanks

Thanks for the reply. If you mounted it under the deck, does that mean it doesn't need to see the sky?

Finally had time to install the speedo. It doesn't work, all it did was go up to 90 (max) and then back to zero. I know I have power to it because the light is lit. I tried taking the antenna out from under the dash and held it in the open just in case, still nothing. I wired it by the diagram don't know what else it could be. Any ideas? Thanks

Found the problem. I'm an idiot. I didn't want to mess with the key switch, so I wired it off of the switch that turns my fuel gauge on and off. It's the line returning from the sender so it didn't have enough voltage. Hooked it up the right way off of the switch and it works great. Thanks for the input.
