Re: spark plug wires

Ya, so how on earth does the same SAE J557 standard for commercial trucks have anything to do with enclosed engine compartments in marine applications. :confused: IMO The SAE J557 is simply a quality standard for spark plug wires that all manufacturers follow.<br />---------------------------------------------<br /><br />There is such a thing as being an alarmist, don't know if that's a word but it fits.<br /><br />I'd be very surprised if the boating explosions shown above were caused by spark plug wires and I am sure the very few that are were more than likely old plug wires in very poor condition. That's maintenance not manufacturing.<br /><br />Cobra 3.0 said exactly what I have been saying all along (Same Exact Construction) but I am sure most if not all plug wire manufacturers are within the SAE spec in their construction. <br /><br />That is why I believe the SAE J557 standard is not an issue to the manufacturers and distributors, not because the consumer is so numb in the brain that they don't care about hearing about that SAE spec or that the J557 spec is meaningless to the consumer or that it should be considered "common sense" just because they are listed as a marine product. Please. In todays market people are more informed than they have ever been.<br /><br />If that were true you would not see manufacturers and distributors of alternators, distributors and starters for marine use explicitly explaining the requirements for these products in a marine application and many going as far as stating that the product is in compliance with the specific SAE J standard in that statement. <br /><br />If they feel it is necessary to "inform" the public about these issues and standards then why would the spark plug wire set manufacturers and distributors ignore it completely. Remember we are not talking about a few here, we are talking about each and every one of them.<br /><br />Makes no sense, nor does your attempts to justify your position that we should all run screaming hysterically out to our boats yanking the wires out and start calling the manufacturers to find out if our plug wire sets are in compliance. :D <br /><br /> Hey everybody, no ill feelings intended here at all. I just love a good agruement...... Just ask my wife, I never seem to win with her so here I am :D

We are regulated to death in this country... all "for our own good" And people wonder why the "gob'mint" pays $1000 for toilet seats and $100 for nut & bolts.<br /><br />I also find it sort of funny that over in the electronic forum, someone is saying the use of ATC style fuses is forbidden in marine application by "regulations" due to the use of aluminum in it's construction. The same fuse that BLUE SEA SYSTEMS uses iin their fuse block. The same BLUE SEA SYSTEMS that Ralph quote above. :D <br /><br />BTW... the SAE is set of manufacturing standards. They are not regulations.

Re: spark plug wires

the key thing with any marine connection is how long it will last with out corriosion<br /><br /> i believe thats the main thing with plug wires how well they keep a good connection at the plug because a bad connection will by nature start to try to find and easery way to ground and spark were it was not ment to<br /><br />tommays

Re: spark plug wires

This whole debate can be reduced to it's lowest common denominator, attitude. I watched people in General Aviation convince themselves that using unapproved parts is okay, as long as the system the parts were used in wasn't critical. Read (I've never saw...) The reason specs were written were to keep people from killing themselves and or others, because we all know we're not stupid enough to do that. But every year, someone blows up or crashes. Be the first on your block to become a statistic. You can always find a less expensive approved part, other than the dealership. What makes me laugh is, after the sh*t hits the fan, guess who the first one to say, "I didn't know"? The owner/operator trying to save some money, doing backyard hack maintenance. Why do I get the feeling that if you follow the manufacturers maintenance manual, and use approved parts, you'll live alot longer, to complain about something else.

Re: spark plug wires

<br />Have a Blast<br />By Pete McDonald<br />September 2002<br /><br />Don't skimp on maintenance.<br /> <br />Almost immediately after taking on 90 gallons of gasoline, a 35' Chris-Craft exploded. The operator was thrown clear across the fuel dock, and his wife and dog were catapulted into the water. Pieces of the boat flew 250 feet. The resulting fire burned the boat down to the chines. Luckily, nobody was killed, but the blame for this disaster fell squarely on the owner. Why? Shoddy maintenance. <br /><br />"When you go the cheapest route possible, this is what happens," says Joel Fuoco of the Nassau County Marine Bureau in Long Island, New York, the investigator on the case. Fuoco listed three things he alleges the owner, a do-it-yourselfer, did wrong. <br /><br />When he replaced the fuel fill and fittings on his boat, he used galvanized pipe from a hardware store and didn't double clamp it. Dissimilar metals were touching, causing corrosion on both the fill and the tank. <br /><br />The owner replaced the fill but not the hose. The fuel hose had wear, so fumes penetrated it and filtered into the bilge. Only one of his four blowers worked, so when he flipped them on, the fumes weren't evacuated. <br /><br />The worst offense: Installing an automotive starter motor. Unlike marine starters, automotive starters are not spark protected—there are no seals to protect the inner workings from collecting gas fumes. In this case, the fumes seeped right into the casing. When he tried to start up after fueling, the spark from his ignition lit the fumes in the ignition casing and—boom!—a 35' boat was reduced to rubble. <br />The funny thing is, prior to the explosion, the boat didn't appear to be a junkyard dog. The hull was in prime condition, with high-quality fit and finish. By all accounts, it was a beautiful vessel. The owner spent a lot of money making it look nice but, when it came to the boat's vital mechanical systems…. <br /><br />It's amazing that people will spend tens—if not hundreds—of thousands of dollars on a boat and then nickel-and-dime the maintenance. Because a boat's systems are often exposed to harsh elements, the more you boat, the more maintenance it needs. That's why it's so tempting to find some inexpensive parts to fill in the gaps. But when you're dealing with mechanical and electrical systems, get the good stuff. When replacing wiring, use high-grade tinned-copper wire. For diesel engines, use high-pressure braided hoses; for gas engines, use A1 rubber hoses. Double clamp everything with stainless-steel clamps. Use stainless-steel or chromed-bronze fittings. (Some of the new plastic fittings work just as well, too.) And above all else, stay out of the auto parts store. <br />

Re: spark plug wires

Wow .........<br />You Guys are Beating the Snot out of This 1.............<br /><br />Although I'm Not in this for the Debate,<br />I'm with Elk Chaser........... For the Most Part, Anyway..........<br /><br />I think Proper Maintaince is the Root Issue.......<br />I'm running a set of Extreme Quality Wires........<br />No where did the wire, or the box say Marine......<br />I'm Not Worried..... <br />I've seen Many motors with Factory Marine Rated Wires, that Sparked All Over the Place.... <br />It's because they were Old Rotten Wires........ No Maintaince..................<br />No Matter a Car, Bus, Or Boat..........<br />I Don't want My wires Leaking...... That means I'm Loosing Power............ :D <br /><br />But,<br />I Also Believe that Many Auto to Marine Short-cuts + Money Saving Ideas are a Real Stupid Move............<br /><br />I Also Agree that we are Regulated to Death.... For our Own Good..... Boy is That a Liberal Idea......<br />You'll find Most All the Idiot Devices on My toys,<br />To be By-Passed..............<br /><br /><br />

Why do I get the feeling that some of us are being talked down to? <br /><br />BTW... Guess I'm really breakin all the regulations... my coil is a NAPA part and does not say "marine". OMG! :eek: <br /><br />Is there a regulation there too??? :rolleyes:

Re: spark plug wires

And the beat goes on...<br /><br />Let me just say this, and then I am done. I am the Captain of my ship. As the Captain, I have a duty and obligation that dates back centuries to keep my passengers safe. If something should ever go wrong, Heaven forbid, I don't want it to be something I could have easily avoided. And, if it ever turned out, somebody got hurt because I was trying to save a few bucks and cut a few corners, I would not be able to live with myself. It's just not worth it.

KaGEE<br />the non marine coil is bad for a nother they tend to fail fast in the damp engine bay from rust fresh is not as bad as salt were they go real quick<br /><br />tommays

Re: spark plug wires

...actually any epoxy coil that resists jarring is very suited for marine use. Up here in Canada, where there's lots of snow and salty streets, coils are rarely an issue in automobiles. Here too, buy a good quality coil...

It was their best one. Just like my plug wires... top of the line. IMO it looked better than the one I replaced.<br /><br />But, what do I know... "I'm just a backyard hack". :rolleyes:

Re: spark plug wires

I will stand on the fact that if you don't maintain your boat properly you are asking for disaster, whether that be stuck in the middle of a lake in a storm with waves lapping in over your transom or in the extreme an explosion or fire.<br /><br />Whether you use marine spark plug wires or not you should check them as often as you check to ensure that your blowers are working properly and that the fuel hoses are intact and not leaking and the list goes on and on........<br /><br />As far as that is concerned I will agree that you are the Captain of your boat and you are the only person responsible for ensuring the safety of all of your passengers and bystanders.<br /><br />It is amazing to see some of the old boats out there that look as if they have not even had the oil changed in decades, kinda scary when you think about it after reading this thread. I will be staying a bit more clear of them from now on.<br /><br /><br />The "tinned copper wire" regulation must be fairly new as I have not seen any tinned copper wire in any of my boats which were all built earlier than 1990. That's a new one on me.

We should form a union! :) <br /><br />I was working on my wiring harness (OMC O.E.M. engine harness) last night, cleaning and tidying things up. Not only was the wire not tinned, there were no SAE codes stamped on any of the wires. :eek:

Re: spark plug wires

Elk Chaser,<br /><br />There is no requirement for using tinned wire in circuits under 50 volts. Also most of the Coast Guard specs and these Federal Regulations are for enclosed gasoline powered inboard boats, outboards are exempt for most items.<br /><br /> CHAPTER I--COAST GUARD, DEPARTMENT OF TRANSPORTATION (CONTINUED)<br /> <br />PART 183--BOATS AND ASSOCIATED EQUIPMENT--Table of Contents<br /> <br /> Subpart I--Electrical Systems<br /> <br />Sec. 183.405 General.<br /><br /> Each electrical component on a boat to which this subpart applies <br />must meet the requirements of this subpart unless the component is part <br />of an outboard engine or part of portable equipment.

Re: spark plug wires

I went ahead and asked MSD about the standard and here is the question and the answer. <br /><br />For what it's worth.............<br /><br />Question:<br />
<br />MSD Spark plug wires are listed only in the automotive section. I can find MSD spark plug wire sets at other distributors listed as marine spark plug wires but I see no difference between these and the plug wire sets listed on your site in the automotive section. <br />Are all these spark plug wires compliant with the SAE J557 Standard required for marine use. If so why are they not listed as being compliant with this standard.
Answer:<br />
<br />Dear Sir;<br />Even though our spark plug wires are commonly used in marine applications, we have never provided any to the UL laboratories for testing so they do not have a UL listing.<br />Thank You,<br />MSD Tech <br />
Seems a major manufacturer of top quality products is not the least bit concerned with the SAE J557 Standard....... <br />Interesting to say the least.
