marine cat converters....

[JustJason]

Indmar's got em.... If i'm reading right, they JUST pass CS regs on temps... anyone an Indmar guy here that can shed some life on realistic life expentancy and cost replacement. Manifolds/risers are pricey enough, i'd love to hear how much they are with a cat in them. I could be totally wrong here.... but I see cat's as severly hurting the boating industry. I mean, how to does one mix "sumptin in the engine box that's realllllllly hot" with engine performance in a small box, and fiberglass???
I'm all about being green here... but i'm also realistic. How's this all going to work long term? and at what price?

Re: marine cat converters....

Brought to you by the same "minds" who thought ethanol in boats was a good idea too....I can't wait to see the replacement prices on these, the whole system is going to make a late model used boat seem like a better idea than ever....Last time I checked, car cats have a heat shield on them....to keep the grass from catching on fire! What happens if your impeller fails, no cooling water to the exhaust with cats that is already probably hot as can be...and you don't catch it right away?I bet they will have a fail safe system that reduces engine rpm as soon as your temp starts to go up even a little bit.

Re: marine cat converters....

dunno, but they are coming.
its an EPA regulation that I think starts in 09, all inboards will have cats.
will it work? dunno but I can see more service work,more displeased consumers and more general BS.

Ayuh,.......

It just might open up the market for Rerigged Classic hulls.........
Possibly making it Financially feasible.......

They will most likely be stainless too. $$$ Makes me glad i got a 1970 with an ole stovebolt.

Re: marine cat converters....

Or better yet, you have a misfire, the cat starts to glow in your engine compartment. Doesn't that make you feel safe?? I have never measured emissions from a boat engine, but my guess is they are really low on boats that exhaust through the water. Some is released into the atmosphere, but my guess is most stays in the water where it is broken down by the micro-organisms.

Have a great day,

Rob.

Re: marine cat converters....

Will this affect outboards as well? I have a hard time imagining a cat on an OB! If not, and it's only going to be an inboard problem, then I can see OBs making a comback on sport boats that have gone almost all I/O because of the cost factor of modern outboards.

Re: marine cat converters....

I know this is is irrelevant......but if we keep electing left wingers we'll have Cat converters on lawnmowers!

Re: marine cat converters....

What are you trying to convert your cat into? A dog?

Sorry, couldn't resist.

It's bound to happen sooner or later. And, I think if you live in LA your lawn mower has to be EPA compliant already doesn't it?

Re: marine cat converters....

As far as EPA regs, I recently bought some new 2 cycle Echo yard equipment (blower and weedwacker) that runs on the typical 50:1 mix. It has the latest emissions stuff for 2 cycles (whatever that is) but I have to say, they smoke less than any other 2 cycle stuff I have, even less than my 1997 Toro snow blower with the Suzuki 2 stroke (50:1). My old wacker n blower both ran on 32:1 and smoked a lot more.
Still I think this is going to cause problems. Can you imagine the heat in the engine compartment of a boat with twin stern drives, with 4 converters (the Indmar system I saw had one for each exhaust bank), can't get away with a single I guess like V-6 and V-8 car engines do. I bet the heat will be such an issue, that they will have put additional vents the engine compartment to let the heat out and increase airflow.

Re: marine cat converters....

Uh....I think ALL 2 stroke stuff (except the Evinrude Etec) is banned in Ca....that is, to sell new. Some lakes are banning all 2 strokes period. (except the ETEC)

A lot of other states are banning them...

Did someone mention this article? http://www.boatingmag.com/article.asp?section_id=1&article_id=858&print_page=y

ALL new manufacture boats are going to have cat converters soon.

Next up, a cat on your fireplace.
Then your bbq grill.

Um.. your really not to far off the mark. In my area of this state we used to be able to burn our paper garbage in our backyard in a barrel. They don't like you to do that anymore. There also has been a few rumors floating around about making people get a permit to have a campfire while camping. No politician is saying that yet. But, I'm afraid the day will come.

Re: marine cat converters....

I'm old enough to remember when you could burn your leaves here in NY. Let's hope you don't have to file an environmental impact statement to make a campfire!

Re: marine cat converters....

Uh? Don't most later model jetski's 96' and newer already have a Cat on them? I believe they do. Just another freakin headache, & extra expense to diagnose, repair, or replace! Don't ya just love left-wingers.

Re: marine cat converters....

No. They don't.

The first production marine catalytic converter is the Indmar one mentioned.....it wasn't clear that it's actually available yet.... Other Marine manufacturers either have them running or are developing them....

The 2001 saw the first 4 stroke jet ski's (Yamaha) and yes "they" probably will require a cat on PWC in the future......

There aren't any (production) 2 stroke catalytic converters....and probably never will be until 2 strokes get all the oil out of the combustion chamber. (I think the BRP/Evinrude Etec is pretty close there too) They are trying though.... The Lefties will probably force them on the marine manufacturers and we'll pay for them!

So, What do you call this then? It sure looks like a Catalytic converter to me? In fact that's what it's described as, on a 2000' Yamaha GP1200 see part #54:
"http://216.37.204.203/yamaha_OEM/YamahaPWC.asp?Type=13&A=83&B=8"
I picked this out as a random example, I'm not sure what year, brands, or models, they started this with? But I was pretty sure it was there!
By the way, check out the price of this puppy!

Re: marine cat converters....

Yeah you're right.....(I hate when that happens!!)

It looks like a catalytic converter to me too!!
I should have qualified my statement I guess!!

There is no catalytic converter that has been successful for 2 strokes. (Yamaha even had one in 1984 that didn't work either) The one you mention reduces emissions by only 50%...Yamahas claim....I wonder how long it lasts....Those catalysts don't like a lot of unburned oil being dumped into them on a continuous basis.... and at $700+ I'll bet not many people are interested in replacing it when it does finally stop catalyzing!!) It didn't save them in getting them certified 3 star....This is probably why all the PWC manufacturers are going to 4 stroke/blown engines.....and eventually cats..... I think BRP has an ETEC engine in their PWC)

btw, I also noticed that the 2006 model also has a "Catalyst ASSY" too! I would bet that as 2 strokes all become DFI, and pressure lubricated they'll get cats like everything else......and we'll pay for them too!!

Re: marine cat converters....

Apparently all the Yamaha jetski's have Cats from 2000 and up, not sure about the other brand PWC's? but, I've read of issues caused by problems with these cats all along, on the PWC forums, and Riva has a "D-plate" to eliminate them.

Re: marine cat converters....

Yeah....I'll bet it's the first thing people remove!
