Curious?

[starsnstripers]

I know it's an absolute to use a marine starter safety from bilge fumes. But what exactly is the difference ? I noticed a rubber gasket seal between the solenoid and where it mounts but thats the only thing i could see different? is it just that it's sealed covers and seams etc.?

Re: Curious?

there was a big post on that one a month or two back...
it was really good.....

im searching

oops

Re: Curious?

Ok thanks, hope it says exactly what the difference is that would be great, I always wondered what it was?

Re: Curious?

this is a wild one .....so wild the mods closed it.

but ......the info is therehttp://forums.iboats.com/showthread.php?p=1530971&highlight=whats+the+difference+between#post1530971

Re: Curious?



hope that works

Re: Curious?

WHAT??? Why would they do that? Are you saying we can't get to it? Well I hope a Mod will reply to this post and explain it then.

Re: Curious?

Maybe someone replied to it and said something against a safety issue who knows? I'd still like to know the difference though.

Re: Curious?

I've pulled one apart and did notice the brushes have shields around them to contain arcs or sparks whatever you want to call it, also yes the solenoid cover gets sealed up, also I noticed there is a small drain hole in the nosepiece so if the bellows were to leak and fill the bellhousing with water the starter will be able to drain itself, and probably the marine starter gets some special anti corrosion treatment on the paint too, I didn't get to see the previous post so I hope I'm not doing anything wrong?

See the post below entitled Volvo Penta Starter rebuild.
At the bottom is a picture of the disassembled starter showing the seals and shielding etc.

Re: Curious?

Yeah I think your right about that stough sealing and brush shields. I'm going to compare the parts breakdown diagrams to see. I dont think your doing anything wrong. Thoughts/opinions, I'd like to know why the post got blocked though? Don?

Re: Curious?

HUH? No takers ? touchy subject "A Starter" somethings fishy! Well, I looked at the mercruiser parts breakdown and it doesn't show any gaskets, seals, etc. Mercruiser must install seals/gaskets and seal them when they get them and maybe install brush shields? Someone must know???

Re: Curious?

I figured Don may have some input here. Hope the storm he mentioned wasn't to bad with power losses etc.

The thread is still readable, just that it can't be replied to. It does make interesting reading too. . The mods have absolute power here. If a thread starts heading off track or takes on 'bashing', even of people or institutions who have bought it on themselves, or the thread becomes a personal attack or respondents become aggressive, or the language degenerates... They click the lock.

So, to get this back on track. There is a very good reason(s) why marine parts should be used in marine applications. Safety. It's the same with the offshore industry. For every 'silly' rule, someone died or was seriously injured.

The marinization of electrical and fuel system components does not stop them producing sparks or sources of ignition, it just ensures that those sparks or ignition sources can't propagate an explosion. Apart from producing a brushless starter there is no way to stop the arcing on the commutator inside a starter, but if the casing is sufficiently screened, gasketed and sealed, even if fuel vapour did get in, any flash couldn't continue outside the housing.

Hope this helps, without getting closed

Re: Curious?

I'm not getting involved, that's how that goes. If you want to know for sure, contact the US Coast Guard and ask them. They are the ones that certifies the starters to be "Marine Grade" and get that JXXXX whatever stamp of aproval.
There is no one on these forums that have the information you are looking for. The manufacturers that get their product certified seldom comes on this forum to tell you how to go about getting the certification.
All we have here is those with educated guesses. Nothing more.

Re: Curious?

Thanks Chris i was getting lonely here. Yeah i know why it's a marine starter, safty from fumes in bildge as well as the Alt. But how is my question like if you want to rebuild one the rubber seal isn't in the parts breakdown or if your seal gets dry-rot or damged. if you get some moister around the starter or you want to take it apart to clean, inspect or service it with brushes/bushings etc. they should have some type of starter seal service kit w/instructions. I was looking for specific differences apart from an auto starter? Are the specifics in that locked post? if so how do i view it? thanks

Re: Curious?

Maybe the info about this subject could compromise safety so i can understand there should be guidelines. It was just something always wondered what made a marine starter "a marine starter" spark arresting features thats what. Good enough

Re: Curious?

Marine starter differences:

A proper marine starter is sealed at both ends,has rubber coated or (varnished) field coils,brass terminals(not copper) and is painted inside as well as outside.If you look into the drive end housing,there should be a plate that carries a seal to seperate the bendix from the rest of the starter.There should be a rubber gasket between the solenoid and the housing and the solenoid cover should be gasketed as well.

Re: Curious?

I got caught up in that post you guys are talking about. It did get a little heated, but there was some great information. There are some differences between marine and automotive electrical and fuel system components, but what exactly they are, I can name some but not all of them. However the important thing is that you are required by law to use marine approved components, and that is what we should be worrying about. Are these parts approved for use in my boat? If a non-marine electrical or fuel system part is used on a boat, and causes an explosion, you may be held liable. The insurance co may try and find any loophole that prevents them from paying for the damages. I cannot second guess the law, I just abide by it. For me, it is not worth risking that for a few $$. Just my $0.02, I like to cover my butt!

Have a great day,

Rob.

Re: Curious?

Yeah, I agree Rob I wouldn't use an automotive starter, fuel pump,carb or alt. In my boat or recomend it. But was curious about the differences is all. thanks for the replies.
