Non-Marine rated Electronics on board

OK. Non- Marine rated, i.e. radios, pc's, clocks, microwave, etc.
On board, out of the weather, out of chances of spray, good ventilation, staying out of 95+ weather, out of 50 - weather. I.E. good 60 - 90 degree weather.
My Nav station and Galley is well below in a very well ventilated and dry area.

What is the general concensus of the electronic / circuit board survivability? 50% more? Less?
I.E. If a system is suppsoed to last 10 years, shouls I get 5 years from it? Should I figure it is disposable anyway and just say to heck with it? Should a, Could a, Would a, you know...
I am talking about going with a Kenwood TS-2000 instead of a IC-802. 1/3 the price, when getting the same capabilities per say.

I've had good luck on the past two boats with car stereo decks. This latest one also is a DVD player too. I use the front and rear speaker outputs to drive the saloon and cockpit speakers. There is also an input for my MP3 player too. Car stereos are almost as tough as some of the better marine units. They claim the marine electronics have a coating on the PC boards to inhibit corrosion. I think many items don't fail because of that reason yet I'm sure some do.

One exception would be car VHF radios suck and you can get cheap marine VHF's if you want a really cheap radio.

I think you judge it like you do everything else you buy. If you use your boat a great deal then spending to get a little bit of quality or more compact and feature friendly is worth it just like you do when you buy stuff for your shore residence.

Buying standard AC appliances to be run off an inverter is something you have to pick and choose. Making AC power isn't the most efficient use of your batteries but for small items it can be great.

(Repeat post) I had an HP Pavillion laptop which survived 5 years in a very wet boat and still worked fine. Generally, I think that the "marine" electronics are a rip off. Some products seal their PCB's in lacquer or some other element.

"Marine Electronics" is an oxymoron.
"Marine Electronics" means twice the price and half the warranty.

There is also spray-on conformal-coating that is easy to apply (careful with exposed contacts, pots, and non-sealed switches, of course); does wonders on printed circuit boards. I have used it to encapsulate constant-current drivers for homebrew high-brightness LED navlights, and they have survived salt spray.

When I have boards that are exposed to ambient air (not in gasketed enclosures), I give them a layer of that. One can also use VCI (Vapor-phase corrosion inhibitors) which are like adhesive-backed sponges, when protecting boards inside a well-sealed enclosure.

As to "marine electronics" in general, quality can range all over the map. I had a marine VHF a few years ago that was mounted in one of the early Microships. It took a bath in dumping surf, and even though the radio enclosure itself did surprisingly well, the cheap power wire and open nylon inline fuse-holder wicked salt water all the way back to the circuit board!

Cheers,
Steve

My on board stereo is a car deck with multiple CD accessory. TV is an AC Flatscreen with a small Sony DVD player plugged into it. Microwave is a $39 special from a discount store. All have and are working well. I did go with marine cockpit speakers since they are exposed to the weather but for below decks I've not seen the need for the extra expense.

A Kenwood TS-2000 is 1/3 the price of an Icom 802 ?

I can get the IC-802 for a couple hundred less than that price of $1823

The Icom M-802 consists of the transceiver unit and remote head. The transceiver unit is not weatherproof at all. It has venting slots in the cover for cooling, there is no gasketing of the cover and no coating on the circuit boards. The remote head is somewhat weatherproof due to the rubber membrane keypad and buttons but the channel knobs are not gasketed nor is the cover.

Icom 735 on board Insatiable for 14 years, still working fine. Icom 746 on Insatiable II for 7 years, still working fine. I-one was not a very dry boat, I-two is.

Don't worry, be happy with your ham rig.

Thanks, That is just what I was looking for. The Seattle boat show is at teh end of hte month. I figured to go and look at one up close and personal. You gave me good ammo for my quest.

Interesting. Only the front panel is 'weather resistant'. A lot of money for?...
