outboards

[mastreb]

I don't think the solitary term "recycled" actually captures all the different ways that used motor oil could be reused. It doesn't necessarily mean that used motor oil goes back out for use in motors.

Firstly, there are two kinds of car owners: Those who change their oil way too often, and those who don't change their oil nearly often enough. Almost nobody hits it exactly right unless they have a car that informs them when they should change the oil using viscosity sensors in the engine.

The old rule that you should change your oil every 3000 miles or even 5000 miles results in a lot of still useful motor oil going into recycling. In point of fact no modern oil need be changed at a higher frequency than 7500 miles in any car, and my twin-turbo car routinely lets me go to 15000 miles (it has a viscosity sensor and I use Mobil 1, which is a Group 3/4 blend).

So a lot of recycled oil from Jiffy Lube or any place like that probably could just be cleaned, blended with Viscosity improver additives and sent back out as bulk fill oil in 55 gallon drums. I don't find it surprising that there is a business is cleaning, improving, and repackaging oil.

But its also true that if you want to drive off oxygen, you have to do it at heat in a refinery process. I would be surprised if there's a market for doing this with used oils.

I would assume that most used oil goes back out as fuel oil, which can be burned in most kinds of boilers. Fuel oil is used in older homes for heat and widely used in marine shipping. Fuel oils make an obvious end-of-life use for any recycled liquid hydrocarbon as those uses do nothing more than generate heat. The oil/steam ship I was in in the Navy could burn anything with a low enough viscosity to maintain proper fuel pressure, and most older commercial ships today still can.

Not speaking from knowledge, just assuming that's where broken down oils would wind up.

For the USA you would be correct only about 10-15% of motor oil is re-refined for reuse as engine lubricant the vast majority is either burnt as fuel oil or illegally dumped. Here in Oz we are the same as the USA only 13% is re-refined as lubricant the rest is used for fuel oil, bituminous product or illegally dumped.

In Europe however about 50% is re-refined for reuse as engine lubricant Valvoline Next-Gen is an example of re-refined motor oil from recycled oil.

why not go yamaha, the 70-90 horse is lighter than everyone else. I believe 70 around 255 lbs this is the 2013 version

[dlandersson]

What are the relative weights of 70-90 HP outboards?

[bahama bound]

i thought etec was the lightest ? there i go thinkin again ???? :

[Starscream]

When I was doing my research, the manufacturers' websites suggested that the Yamaha is one of the most gravitationally challenged:

320 lbs for the E-tec 90
380 for the Yamaha F90
359 for the Honda BF90
375 for the Mercury Optimax 90
341 for the Suzuki DF90
399 for the Mercury 90 EFI Fourstroke

After that, the Yamaha website gets very weird: http://www.yamaha-motor.ca/products/det ... el=3177#ts... shows an incredibly light (261 lbs) and cheap 90HP outboard but you can't navigate to this page from inside the Yamaha website itself, plus no photos, model number, etc. Not sure if this is real...or possible...but it's on the internet so it must be true.

[dlandersson]

It's so true...

Its probably the 90TLR, Its an old school carbed 2 stroke that they still make and import occasionally as emission credits allow.

Weight is one of those specs that stands out because it can be easily compared on paper, but doesn't mean as much in the real world IMO. Take the pepsi challenge and I doubt you would notice the difference in any of them when sailing and the heavier motor will feel more stable when motoring, at least that’s what I found going from 200 to over 400lbs. For a 600lb skiff it’s a big deal, but unless you have a totally stripped mac it would be one of the lowest criteria on my list when choosing a motor.

On the US web site, the 90 HP weighs in at about a 100 lbs. more.

Case of beer weight = 31lbs

[SENCMac26x]

Case of beer weight = 31lbs

True,

But the more distance you cover, the lighter that case gets.

Not true with an engine

But could you get a smaller, lighter engine and then add more cases of beer and care a little less when you get there?

[Starscream]

But the more distance you cover, the lighter that case gets.

Only true if you are a-peein' over the side as you go. If you have a blue hull, aim off the back...will help you go faster.

But seriously, I don't believe that you can actually buy a 261 lb. 90HP motor from Yamaha.

So does an engine get lighter while it's a-peein'

Maybe not in the USA, but here ya can.

It weighs less over there only because you guys are down under. Everybody knows that
