I have wet exhausts on my boat that run the length of the ****pit, and like all diesels, I am getting some soot buildup on the hull each time out. I'm good about scrubbing as I get into port, but I just can't keep up with it

Anyone have any tips on what I can use to at least cut down the amount of time to clean the soot off?? Any magic cleaners out there that I haven't tried? At this point the only thing that keeps it as clean as I want is to compound and wax it once every two weeks or so, and it's getting tiring!Below is a photo of what the exhaust ports look like.. they are the small holes pointed down.

Thanks,

Ryan

There was a guy on another site with a bad soot problem on a fairly new Luhrs. After chasing it for a few years and replacing many of the interior rugs and fabrics because of soot, someone finally discovered that there were NO air intakes provided to the Cat's.

Tey were starving for air hence the soot, unburnt fuel.

You might want to look into that as a possibility, as far as cleaners Simple green works well on oil based stains. Also an application of Rejex in that area may help.

Had that problem on my 43 Viking. Problem is gel coat absorbs the diesel soot.
nothing works all that well to clean it other than compound and wax.

I finally solved the problem by putting a coat of clear coat paint over the gel coat worked like a charm soot comes off with soap and water easy as can be.

I felt it was well worth the expense.

Heard about a few problems about Luhrs and their antics of late....I really feel bad for the owners of those boats....shame really....

I have large vents port and starboard, as all Henriques do... The engines breathe fine, and the soot level is on par with the engines. I really think this may be a design issue with the wet exhaust.... I'm not an expert, but from what I have seen, the exhaust exits the ports, hits the water wall and then curls up and at the hull, hence the unsightly soot stains...

Blinkey,,, how did you manage the clear coat, and also, how did you blend it into the existing gel coat, if at all?? I like the idea.... I've also heard of people applying PAM cooking spray to the sides of the hull for easy cleanup...everyone has their own voodoo with this it seems,,,,

Thanks,

I have found that if you wet the sooted area and use Wisk full strength on a soft brush works excellently. There is something in Wisk that cuts soot.

I hired a pro, it's not that expensive and it gets sprayed right over the gel and then sanded out and buffed. I had it blended around the corners about 12 inches and never had a soot problem again.

BTW I was told to do this by one of the owners of an MTU / Detroit dealership.
