2005 Sea ray 340... So this boat never had Radar before... I want a radar mount that has the light bracket on it already... How do I know what pitch I need for the Radar.. If it helps I'm going with a Garmin... I know they all pitch 1 way or the other...
 
I went with a 5" Seaview. Its a modular system, so you'll need a mount, a top plate, a light pole and a light (I went with the LED version...mo more burnt out bulbs). They sell wedges to increase the down angle if you need it, just depends on your system. I elected not to us additional down angle, this works really well.

Looks great and it's solid!!!

Sometimes I wish I wasn't on a trailer. The top of my arch is 12'3" from the ground. So when I get the radar for mine, I can't use a mount. It will have to be right to the arch or the first traffic signal will take it off. Those look sharp.
 
With the boat sitting in the water place a level on the arch and measure the angle of of downslope or upslope on the arch at the mounting point.
Given that the radar has a 22* of horizontal view and radar will be used at minimal speeds use the pedestal that provides closest for 0*. Using nylon spacers adjust fore or aft elevation as necessary.

look into a flip mount, There was two knobs that you loosened up and the whole radar and half the bracket would flip under the arch so it was out of the way.

Did not use any spacers to get more of a down angle. In all honesty, the only time the radar is on is when we go out at night and that is almost always at "cocktail speed", so the way it's mounted now seems to work ok.

The mounting point on my arch was dead on level with the boat sitting in the slip. I measured the angle underway at 5 knots and found that using (2) 3/8 inch spacers between the radome base and the sea view mount provided a nearly level mount with maybe 1-2 degrees of the base having a forward down tilt.
My rationale was if it is necessary to use the radar the speed would be slow, 5ish knots, and a very slight down angle would assure that any objects in my immediate forward course would be visible on the display.

I like the flip idea. And I have looked at that route. The only reason I have steered away from them is that I have the full camper top and don't want to have to remove it for travel. Road grime from the wet roads on the interior is the biggest reason. If I mount the radar to the arch it's self, then it shouldn't be too much of an issue. It will sit just under the 13'3" and be the same height as a semi trailer. And it will be under the 13'6" so won't require the over height permits along with the over width permits. Thus keeping me from hiring a pilot car for about 90% of the roads I will travel.

But, at just under $400 for the mount, it is lower cost than the removable mount I was thinking of needing to have a removable radar.

While these are not the same boats it might hold true for yours. When I replaced my radar I contacted Sea Ray for the recommended angle of the mount. They told me it was a 0 degree mount and the arch and pad were compensated. I have had no issues of getting a good radar image while up on plane.

I appreciate everyones comments.. Usually at night we are either at cocktail speed or we are on cruise running back from the city or a firework show...
 
I contemplated a 2 degree wedge, but having used it for a couple seasons, I also like 0 degree. My radar can see right in front of my bow, but also, it gives good coverage to the rear and sides as well, and the doppler will mark anything coming at me from any direction, so I know what's in my blind spots.
 
To see if a wedge is needed or not just take a torpedo level on the flat of the arch at cruise speed and you will get an idea of whether or not one is needed or not. If one is there is a bigger discussion around here on determining and setting the angle needed. Usually a 4* wedge is needed as a starting point.
 
Thanks guys just ordered a Seaview mount and a full Electrons package for the boat.... Now hope I can Install it all...

Agreed. I'm also using a 4 degree wedge.
