First outing 2008

[cfelton]

My wife and I took the V out Saturday. We rode about 40 miles altogether. My boat ran great, no problems at all! I was a little concerned with the fuel consumption though. It used about 12 gallons of liquid gold! After talking with my buddy with the 86 V with the same motor ,he said his was much better than that. Ive got another carburator that ive already rebuilt that Ill try. Maybe it will get a little better mileage. Overall we had a great day out though!!

3.3 MPG aint too bad.

The 2 stroke outboard guys would kill for that.

Not this one. I'm doing much better than that.

[Airslot]

3.3 is what I've averaged over the last 4 years or so that I've kept track with my 150 2 smoke.

3 letters for you, DFI. Them there direct injected motors can do pretty good now. I'd be happy to get 3.3 out of my flats boat, but that old 150 MERC likes to run.

Or in my case, HPDI. It's very efficient, and clean-running. Not as quiet as a 4-stroke, of course, but it's lighter than a 4, and if you're into the hole-shot it'll grab your attention.

Let me rephrase that......3.3 mpg, that is terrible. You might as well be running a 2 stroke outboard, getting that mpg.

[macojoe]

3.3 is fine for a 2 stroke! I was running 86 Yamaha & 89 Evinrude both 175 hp average was the same for both 2.5

I will be happy to get the same with the Sea Ox??

I am only averaging about 2.25 out of my 2000 Johnson, but those loopers are known for drinking gas and oil so I can't really complain.

Like I said......Those 2 stroke guys are enveous of 3.3 mpg. (Man, I feel like John Kerry)

[bradford]

With a 225 looper I don't even want to know.:cry:

I think John took lessons from you.

Hummmm which side do I want to go with this time???? :devil:

[cfelton]

CY, what kinda milage are you getting? We got the same setup. My 170 I/O has been bored .040 oversized, and I can see it could take a little more fuel. Maybe Ill rejet the carb with a couple size smaller jets and give it a try.

[spareparts]

check the power valve(brass thing in the bottom of the fuel bowl, they tend to get crap in them and stick open and will dribble gas into the engine, also check the plunger that pushes the power valve open, make sure its not sticking. Some of the rebuild kits come woth a new power valve, I ususally don't use them, they don't seem to be of the same quality as the ones that are in th carb from the begining. Do you have the Mercarb( one idle mixture screw) or Rochester(two idle mixture screws)? If you have the Mercarb, try and find a Rochester off of an 888 Mecruiser, they will adapt with a little work, and will run, idle, and perform much better than that Mercarb, at the very least, try to find a later model Mercarb that doesn't use the double lipped accelerator pump, the internal metering was redesigned to fix soem of the issues with earlier Mercarbs

[cfelton]

Thanks Spare, I've got a Mercarb on it now. I rebuilt it before I put it on and it runs really good. The original carb is a rochester with the 2 jets at the bottom of the barrels. I put a kit in it but the jet screws were broken off flush with the carb base. It ran ok but leaked a little gas into the throat after I cut it off. I removed the retaining tab,spring and ckeck ball and cleaned it well. After replacing all the leak stopped, but with the jets broken off I couldnt make any adjustments on the high speed side. Ill try and get those broken jets out and replace them and maybe try it again. Thanks again!!

I get 5 mpg........thats all I've got to say about that.

Thank goodness someone with something constructive to add came along.......thanks SP.


No wait, I don't agree.

Well, maybe I do.
