Running rich ? - pic
 

Is this exhaust soot from running rich?

Not sure but I want to know what boat that is with quad bravo's?

Are they diesels?

Nortech? I saw it when I pulled into my storeage one day. It looked like the owner was fixing the trailer brakes . . . I waited around for a while, but I never saw anyone
Pretty sure that they're gas

They are gas motors

Wow, thats pretty cool. Love to see the engines.

Could be but when I keep my boat on a lift I had to get 89 because thats what was on the water and would get soot like that. Now that I trailer I use 87 and no more soot.

Wow! I wouldn't want to feed THAT beast! And yes, mine with only two will soot up the transom pretty good.

Octane may be too high. IE, higher than necessary if they're stock engines.

Yes.....When I first got my boat with HP500EFI's I figured I would use the best gas.....the highest octane. My transom looked like that at the end of the day. Use the right octane and it won't look like that at all. But if they have superchargers....rich is better than not!

i want to see engine pics thats alot of weight back there.

Both my Fountains look like that after a few minutes of running. Have to wash the swim platform off ever time I stop to keep from tracking black soot in the boat. Always chocked it up to the exhaust swirling under the platform.

Could be a couple of blown power valves if it just started doing it. Have the motors backfired recently?

I'll have to wait around longer for the owner to show up next time to get more details . . . The two times that I've seen it, no one has been around.

they are not stock power...i think he has NA potter engines.

my stock merc 502's do that all the time
It is actually cleaner, but still some soot, when I used to run 92 ten years ago.
Now I just deal with it. :)
a $4 bottle of cleaner is cheaper then the price of premium :)

Looks perfect to me.

It's easier to wash some soot of the transom, than it is to chisel the pistons out of the headers.

Awesome!:drink:

One transom assembly doesnt match the others

I've been telling guys that for years... :drink:

Is that a tandem axle trailer? Kinda looks like it may be tandem duals, but can't tell for sure. That is ALOT of weight for a tandem, isn't it?

Looks normal to me. The underside of my swim platform and transom gets dirty from the exhaust. I run on regular gas.

The soot looks pretty normal. The brown stains on the underside of the swim platform look like they are caused from heat. Might need some more water induced into the exhaust or direct the exhaust tips at a more downward angle.

What Kind Of Boat??
 

It Looks Like A 50' Hustler Powerboat??

What A Gas Bill!!!!!!!!!

The one that is different is probably original. :) :drink:

It is a trip, with the front wheel missing. Look closer at the length of the fender.


btw, this thing has blowers, so that could attain to it running rich. (look for the water spot by the drives) :)

I have to do the same thing. The above the swim platform exhaust makes it pretty bad.

The 93 octane at my marina is ethanol free so it's worth a little soot....

when I am rafted with boats that have diesel generators I get a pretty nice soot line that looks like that. Although, in this case I just think she's just runnin a little rich. Sweet ride!!

I've seen this boat and I'm pretty sure it's NA, as mentioned above.

The last 20' of it is all engine room. Sounds incredible running down the lake, too!
