What is it?

I found a cylindrical component hanging of the right side of my 2GMF. It says SeaRanger on it, and looks like it was hooked into a + connection at one time. Any ideas? Perhaps a sending unit of some type? Any help would be appreciated. thanks.

Have something similar

I have something similar hanging just back of the oil filter, often wondered what it was. I assumed it was for some sending unit eg amp meter ect.

LORAN?

I think I figured it out. It has something to do with the old Loran navigational system that I believe was installed at one time.

Ken, that does not sound right. We have...

a Loran radio on our boat and the only thing connected to it, other than power, is the whip antenna mounted on the pushpit rail. Terry

signal booster?

Well that is interesting, I thought I had it solved. This little device was a one time directly wired into the DC panel, via a positive wire. It also had another outbound wiring connection, with a screw fitting. The reason I thought it was associated with the Loran is that I have the old Loran manual, which came with the boat, and it is was a "SeaRanger". Yes, a weak deduction, but it is all I have so far.

Probably an electrical filter

for reducing alternator noise - electrical noise - not sounds. They are sometimes used on sensitive electrical equipment like radio receivers, TVs, computers, loran, radar, etc. They cut down the voltage spikes and any AC component of the DC power source ie: alternator output, electrical motor noise. There should be a connection to DC ground (usually the metal case), another to the power source, and another to the device for which it provides filtered power. It might provide power for several devices. If you have an AM radio powered by the 12 volt system, you might hear the electrical or alternator noise by tuning the radio to an unused frequency and listening to the audio. It will affect the picture of a TV. If the alternator is creating interference, you can hear it change when you rev up the engine. If your refrigerator compressor is turned on, you may hear it turn on and off and the same for water pumps, bilge pumps, lamp dimmers, or inverters. Without a filter, those types of electrical interference may be more of a problem ie: louder. Some of the noise is not carried by the DC wiring but rather is picked up by the receiver. To figure that out, use a battery powered radio and compare what you get with it to what you get on the DC powered radio. If it is not connected, I would take it out.
