Best bet (although there's no reason you can't put it somewhere else) is stbd side, outside the window. Google for pics of your boat - I'm sure there are a ton of them on the net that you can find in 8 seconds. But generally, that would be the easiest location. Even at that location, though, there is no "exact" spot - just look at the area, including the backside, and do it. Believe me, this isn't rocket science - don't get too caught up in the 'perfect' location - just put it where it makes sense to you.
