Risers and elbows.

[REBrueckner]

Hadn't noticed this thread before: I've posted previously, "copper" risers" have for years been the way to go. Whether they are really just every day copper, whether they are a thick walled tube, or whether they are a different alloy for the marine environment, I have never found out....but for 1960's and 1970's 6V53's and 8V53's they have been the long lived ones I have discussed with other owners; for some reason the "stainless" risers have been more of a problem...that could be poor quality welding, different sources, or the wrong type stainless.

The metalugry in these risers could be key and I'd go with exactly the choice made here, from a reliable source that's been in busines.

I had a 1961 3KW Onan for 22 years...it burned thru heavy cast iron exhaust elbows (with raw water injection port) every two or three years....and it was NOT used excessively....I replaced it with an especially thick walled stainless elbow, also with a 5/8" raw water injection connection, that I found in a local plumbing supply house.....never had another problem in the subsequent 14 or 15 years I continued to own the boat.

Sounds like a good choice, Maynard.

When are you coming back to MI? My boat splashes today.

Thanks Sky...We got back last Thursday, but I am not sure why. This weather is awful. We picked up our new Chevy Volt. What an awesome car. GM did their homework on this one. I kinda wish I had bought 2.

 

[jim rosenthal]

One for each foot, Maynard?

 

[Maynard Rupp]

Naw Jim...One for me and one for my wife. I take great pleasure in not buying any gas.

 

[Jackman]

I don't get it...takes burning coal and nuclear power in some cases to make electricity to charge these cars. Only go 100 miles and you have to charge. How practical is this for the commuter, traveller or businessman? How green is this if the electecity used to charge is not from a green source? Am I gonna get squashed trying to get on a freeway? Like the idea and they look neat but how practical are they. Educate me. I might be interested in one at some point.

Not to mention the huge battery full of hazardous material. It is pure feel good stuff.

Not to mention the huge battery full of hazardous material. It is pure feel good stuff.

And after 8 years or 100,000 miles it cost thousands of dollars to replace them!

 

[Maynard Rupp]

First: because the battery is gauranteed for 8 years does not mean they are junk after 8 years. The projected life is much more than that.
Second: yup, they don't run on air, but it costs me about $1.20 to charge it for 45 miles and we are not buying oil from people that hate us.
Third: You would be amased how little the average person exceeds 40 miles per day, unless you choose to live a long way from your workplace. Then I have no sympathy for you. Please don't blame the Volt though.
fourth: This is one sweet handling car with uncanny acceleration. You won't have a problem getting up to speed on a freeway ramp. You may get a sore neck from the swesome pickup though.
GM did an great job on this car. I have never had a car that workrd perfectly from the first day. This Volt does. In one week we have driven 400 miles total including a 200 mile round trip to our cottage. Total gas consumption is 2.8 gallons. Don't sell this car short. It is awesome!!

To think this thread started as "risers and elbows". My .02. Genesis already did the math on the Volt in a previous thread- and flamed many asses, my own included! The math is the math. BUT, the math isn't everything. The Volt is a step in a process- a very nice step. Remember when all of you troglodites predicted THE END because of emission controls? Or even the end of leaded gas? Reminds me of the story of Honda's CEO dealing with a young engineer who pointed out that being "in front" on the new unreasonable US emission standards would preclude "profits" for several years. The CEO just gave the kid a wry smile, saying "the kid doesn't quite get our corporate philosophy". It ain't about winning today, it's about winning long term. We don't go from better gassers and diesels to the "ultimate freaking people-mover" in one step. It's a never ending process.

Remember Mr. Rupp used to do rides that burned fuel like a Saturn V! I don't want to go that fast unless it's on a Boeing!

So if you take the 37 MPG which is realistic but maybe high if carrying 4 people and gear and compare it to a regular vehicle it's not so great. In fact if you take into account the 600-1500 lbs of gear I often carry around and 4 passengers I am taking with me my diesel pickup getting 24 MPG is better than 2-3 volts straining to carry all the gear.


I understand many people do only travel a few miles a day and do it alone but some of us drive 40K miles a year and can''t not work because the car is charging or can't carry the stuff I need.

I think I will stick with the truck.

 

[Maynard Rupp]

It's not for everybody, but believe me, it is a real car. We get 40 mpg. on gas only with 400 lbs. of gear and stuff for our cottage in back and 2 of us in front. The first 48 miles were all electric. I don't think you can do much better than that in any real car. This Volt is way more car than a Toyota Prius acording to the Prius owners that have bought Volts. Try one, you'll love it.

 

[SeaEric]

My 2003 E Class Mercedes gets 31+ MPG on straight out highway trips and has, according to it's computer, averaged 25.9 MPG in all the miles driven since I have owned it. All in all I think that's quite acceptable, even by today's standards. I paid cash for it the day I bought it, and will quite happily keep driving it. Of course, YMMV. And it still has it's original risers and manifolds.

 

[MikeP]

I'm an old Mopar muscle car guy; if it can cruise at better than 13MPG I'm happy!

 

[34Hatt]

First: because the battery is gauranteed for 8 years does not mean they are junk after 8 years.

Good Luck with that! O.K I'll say 8.3 years


I have to say though I think that 8 years is pretty good coverage. But there are cars out there that can do 40 mpg with out any battery's. Well one to start it.

 

[akintosyali]

i would love to find a way to replace my risers and economically, but I doubt there is a way to do so.

I just got a highlander hybrid, 33 MPG in the city. with a 3rd row seating, and large back, I am sticking it to the oil people before they stick it back to me at the marine gas pump.

 

[krush]

I get 40mpg in my tercel....it cost me $1000.

 

[SKYCHENEY]

Just bought a Jetta TDI. I get well over 40mpg easily at highway speeds ++. City driving has been 32+. 500mile+ range on a 14 gallon tank and half the price of that Volt.

 

[sofarelli]

My boat gets about 1 mile to the gallon, my GTO gets 6 miles
to the gallon, and my RV gets 10 mpg. To offset that, I walk to work.
I would like to think that I am doing my part to both reduce my carbon
footprint and stimulate the economy. It is not an easy job!

 

[sofarelli]

Back to the risers- replace every 3 years at the max here in Florida.
We change the raw water pumps as well. I can usually tell by the amount
of steam from the exhaust when we are due.

 

[jim rosenthal]

Maynard, you have burned more than your share of fossil fuel, including nitromethane, if I am not mistaken. So driving an electric car is what you should be doing. You have also motivated me to try one out. Except there is no longer a GM dealer in Annapolis, MD; they got toe-tagged a year or two ago in the big GM meltdown. But I will find one and drive it. Especially if I could plug it in at work at the hospital. I am spending $100/month just on gas to go to the hospital to work. Can I lease one for that much?
