I have a new Furuno FCV 620 that I am installing. I have the unit flush mounted in the dash--looks good--and I have a string fished to the bilge. The connector is 3/4-inch diameter. I am struggling with the thought of drilling a hole that big thru my transom into the bilge to pass through that connector. Can I cut the wire and then splice it back? The instructions say not to. The splash well has a sealed 12 X 18-inch hatch. I could go thru the splash well drain and then drill thru next to the hatch cover and seal that somehow. Also, the boat came with a speed and temperature sensor that is mounted on the starboard side already. Can I mount my AIRMAR P66 triducer on the Port side of the motor? The instructions only talk about mounting it Starboard of the motor?

Any thoughts or suggestions would be appreciated!


ASIDE--Jim--I did what you suggested on my 2007 200 Dauntless with 175-HP Verado: pulled the connectors half-way out and then pushed them back in. It fixed the problem!

I run the cable from my SONAR transducer vertically on the transom, over the top of the transom, and then down and across into the large access hole through which all the rest of the cables go. I would not drill a large hole in the transom just to pass through a single SONAR cable.

As for location of the SONAR transducer, I have mounted them on either side of the outboard engine with good results. The recommendation to use Starboard side mounting is likely based on having a right-hand propeller. The transducer is upstream of the propeller in an outboard transom mount, and I don't see the propeller rotation affecting the water flowing past the transducer.

With a current model Boston Whaler boat, you can be guided by Boston Whaler's practices regarding transducer cable routing and installation location. In classic Boston Whaler literature, the SONAR transducer is recommended to be mounted on PORT. See html#fathometer
