I would like to control my Raymarine ST1000 Plus Autopilot, somehow
from a GPS without use of the internal compass. This would eliminate

I am trying to figure out what I need to do to get my DVD player to play
through the Aux-Input of my in-dash CD/Stereo.  I want to have stereo

The DVD player has RCA jacks for audio output and if I connect them to ...

I'm about to buy my first GPS for my boat because my LORAN finally died.  I

there is somewhere online I can go to look up my boat's speaker and
radio size? I have found a bunch for vehicles, but nothing for boats.
Thanks in advance.

12v) so that I don't required an inverter?  The monitor is ASUS

I have a small Furuno radar where the echo return image is missing on the
left and right portion of the screen. The fore and aft images are fine.
I suspect the "brushes" or slip rings in the scanner unit are worn in the 2

I am thinking of buying a Garmin 76csx Gps and an Icom M422 VHF.  The
Icom will transfer NEMA data to and from the gps for position display
on my or another boat's gps.  Use will be on a sail boat and I'd like
to be able to use the gps at both the helm and in the cabin where the

I have a Robertson/Simrad AP45 pilot currently using mechanical relays to
control the steering pumps. Pumps are 240 VAC not sure of the HP or current,
probably 2 or 5 HP motors.
Is there any reason I can't replace the noisy troublesome mechanical relays

Looking to fit a resistor/relay combination in the supply line of a
3600VA 240v isolation transformer.  I reckon the resistor should be 8
