I have a 2002 [130 SPORT to which I would like to mount a Fish Finder (FF), but] the cup holder takes up the only area that would seem to be a good location. [What is a good model of Fish Finder to purchase and where is a good location on the boat to install it?]

Whaler also gifted the 150 Sport with a console top almost useless for electronics.

I'm considering the RAM-mount system to the GPS/fishfinder directly behind the steering wheel. You might find something in their line suitable for your application.

If the FF will be a combo with a GPS, I'd definitely go Garmin. Their GPS menu system is easiest to use and their BlueCharts are good. If FF only, Garmin, Lowrance, and Furuno all make good fishfinders.

I used a Ram mount to install a Lowrance sonar/GPS on my 2003 130 Sport.

The mount, with a 2 1/2" diammeter mounting surface, is located against the cup holder, at 11 O'Clock, and the anchor light receptacle at about 2 O'Clock. Height of the mount is 4 1/2".

I've found this to be a good location. The Ram mount does not interfere with the use of either the cup holder or the anchor light.

Sorry I don't have a part number and am unable to post a pic.

Good luck.

Thanks for the suggestions, ram mount it is.

Removed the anchor light receptical and mounted a Hummingbird unit in its place.

How about the transducer, where did you mount it? The location I chose is apparently not the best and maybe the worst. Took Hummingbird's suggestions, 20-inches from the [engine] shaft and it will not read the bottom at planning speed.

The transducer must be located so it is still immersed in good, non-aerated water when the boat is on hydroplane. On a small boat like the 130 SPORT, going 20-inches outboard from the engine lower unit may be too far. Your transducer may be out of the water at that point along the hull when the boat is up on plane.

The transducer is going to be upstream from the engine lower unit, and I doubt that aerated water can move upstream against a current of 20-30 MPH water to travel from the engine forward to the transducer. So I think the effect of the lower unit being a possible disturbance is exaggerated in some instructions. Often these general instructions include use with inboard boats, and in those situations the propeller is upstream from the transducer. Of course, that is going to put aerated water from the propeller stream into the transducer, but not on an outboard.

A good way to test locations is to mount the transducer temporarily to a 1X4 pine board. Clamp the board to the transom with a C-clamp, and go for a test drive.

Also, at high speeds, the depth of the transducer become quite critical. A change as small as a quarter-inch can affect performance.

My transducer (130 Sport) is located 15" starboard of transom plumb line. (center line to center line). Depth is approximately 1/4 inch from bottom of hull to horizontal center line of transducer.

This location works flawlessly from idle to WOT.

BTW. I take no credit for the transducer location as my sonar was a dealership (P&J Marine) install. :)

Thanks for the positioning info, I may heve to change mine after the season. Five inches must be the difference, as I have raised/lowered/tilted the transducer many times.
