Starter solonoid - marine vs. Auto

[jlinder]

I have a problem with my starter and am pretty sure it is the solonoid. On this engine it is mounted on the starter and can be replace separately. (1988 GM 5.0L engine w/ OMC sterndrive)<br /><br />I know I need a marine starter to protect from sparks igniting gas fumes, but from what I can see the generic replacement solonoid appears sealed.<br />

<br /><br />Is there a marine solonoid that I need to use? Anyone know?

I don't know Jack... if it don't have the JE numbers, I'd keep looking.<br /><br />A local shop should should be able to find the right one, or try NAPA. The OMC # is 3853869 per Doug Russell. The GLM replacement # 72430. Also check Sierra 18-5837. NAPA sells Sierra, so they may have it.

KaGee,<br /><br />Found it at NAPA as their part number ECHST128. Doesen't look any different and double the price, but still only $41 and I feel much better knowing it is marine grade.<br /><br />Thanks a lot.

Found the right part is an Echlin ST107.<br /><br />Problem is that although NAPA says the Echlin is a replacement for the Sierra, but I can't find anything that specifically mentions it is marine rated or sealed.<br /><br />On the other hand, comparing it to the original, and examining it closely it seems pretty obvious that this is a sealed unit. I would just feel a little better if soneone said so.<br /><br />Anyone know?

For what its worth, I don't think a solenoid would matter. Its a sealed unit, with the spark happening inside as the electro mag slams a rod with a washer into the two contacts. It wouldn't hurt to call a few boat dealer service departments though. Just ask if a starter solenoid is a Marine fireproof item.<br /> Also the only time it would spark would be during initial cranking, and you should always have the blower on then anyway. But also don't forget step one. Often, and I mean stick your nose down there, and with a paper towel, check you fuel lines. Best defense is good maintenance

Marine solenoids may be made with more corrosion-resistant materials. I dunno. But as a mechanic, I'd risk my boss's business if I put an automotive part in a boat where marine-specific parts are required. Not to mention the lives of every person aboard. Is that worth a few extra dollars to you? If the difference were $hundreds or $thousands...but a lousy twenty bucks? You can barely fill a 6 gallon tank for twenty bucks anymore when you add in the oil. PRIORITIES!

When the boat blows up are you going to say..."I guess it wasn't a marine solenoid after all"<br /><br />Or...<br /><br />"I am the attorney for the boat owner in the explosion. Can I get the part numer of that solenoid you put in my client's boat"

NAPA and many auto parts stores have OEM cross referances if the auto solinoid is listed for both uses then the items are interchangeable. Other than that most auto parts stores have either Prime line or NAPA marine catalogs to buy parts from that are built for Seirra for marine use the same line of parts are available here on iboats. When replacing that solinoid you must seal the solinoid flange to the starter with sealer to make it coast guard approved, it don't matter who builds it something that is seldom is done in most marine shops

Sometimes the PERFECT answer pops up here at this wonderful site! Thanks, Laddie

Re: Starter solonoid - marine vs. Auto

Laddies,<br /><br />Thanks - great help. The Echlin is listed as the replacement for the Seirra, and appears identical to the original in shape and sealing.<br /><br />You are right, the only place that it could have an opening to the air is around the flange where the solenoid mounts to the starter. For what it is worth, the original starter had no sealing - no gasket, no sealer, nothing. It just counted on the solenoid flange which sticks into the starter to help seal.<br /><br />I did finally reach Echlin after an hour or more of trying to track them down (http://www.napaechlin.com). They had been sold twice and it was tough to find them.<br /><br />They are checking to see if they have a formal marine rating on the solonoid.<br /><br />bruceb - I am confused. It seems like you are of the impression I am trying to save a buck - I am not. I am just trying to make sure the part I can find will be safe, that is why I am going through all this.<br /><br />Thanks for the help everyone, and I will post Echlins answer if they get back to me

Jack,<br /><br />Wasn't directing anything towards you at all. Just a general comment.<br /><br />Bruce

Re: Starter solonoid - marine vs. Auto

Understood. I agree, safety is not a place to cut corners. And with our society, the appearance of cutting corners with safety can open you up to all sorts of liabilities

Re: Starter solonoid - marine vs. Auto

Well, I said I would post if I got an answer from Echlin. Talked to their tech (800-732-4832) who checked their catalog (it is not online) and the part is rated for marine use.<br /><br />So now I feel reassured.
