Posts: 47 02/08/08 19:54:09	Tags : None I will not clean the transom everytime I go out next summer. I intend to reposition the exhaust outlet to the side of the hull. I will also see the water coming out. Kent of Catalina told me that he was going to send me a drawing...Apparently the Australian dealer always gets the side exhaust.Still waiting for Kent. Has anyone done it and where was the thruhull installed? Pierre SHUMKA #899 #899 2 cabin Pullman

The injectors or injector pump can cause unburnt fuel to pass with exhaust causing a film. are you using excessive amounts of oil. Just a thought. I would think relocating is a big expense. Jon

I always thought this came from exhaust swirling around in that cavity for long periods, exhaust which I could smell but not see. This is based on putting nearly 700 hours on the engine during more than two years of cruising. I agree with Jon that I would first look at oil consumption, prop size, injectors, RPM usage, etc before undertaking a relocation. Good luck on your search... James Collins

I also had 3 different props on this boat ,the fixed p., Autoprop and Maxi-prop. I also tried different additives. Some gave minor improvements. #899 2 cabin Pullman

Posts: 169 02/10/08 18:47:05 Moderator	Pierre: I too am curious about the reason for your black transom. My boat is only 7 hulls from yours and I do not have the problem you do. I have the stock prop and cruise at 1800-2500 RPM. Has your tach been calibrated? Ken Fischer 2005 C42 #906 "Solaria" 3 Cabin Pullman, Fin Keel, Mast Furling Main, 155% Genoa

Pierre SHUMKA #899 Hi Pierre I've noticed on the C42's around the club that there is a bit of soot on the transoms, but it isn't very pronounced. On TPO, I will get a cast that looks like a bath tub ring if I motor for an extended period of time. Fresh fuel and clean filters seems to go a long way to eliminating the soot, so perhaps you should look at getting your injectors cleaned? All it takes is a single load of bad fuel to mess things up. With regards to seeing the water come out, I can tell you that the exhaust sounds quite different if you start the engine with the cooling through hull turned off.

Posts: 4 02/11/08 15:42:55	Hi Pierre, I was just reading all the 'stuff' and thought I would add my two cents. I had a similar problem on my 1983 C30. I know it has a much different exhaust port (directly on the bottom of the transome) but after about 10 hours of motoring, the transome would be 'sooty'. What I found was the wax I was using seemed to grab everything it could (soot, black streaks, etc.) I like the 'Colinite Fleetwax' because of it's cleaning and polishing properties, but because of it's high 'oils' content, it seems to grab and hold on to stuff. It will still bead water at the end of the season but is black with stuff. I just thought it was because of the older gel coat untill I put it on our 'new to us' 2001 C42 last summer. I had the boat polished in Annapolis in March, 2007, delivered it to my home port in early May (53 hours of motor sailing @ 2800-3200rpm) and execpt for the 'salty' ride, we had a fairly clean transome. Then a month and a half later, I thought I could improve her by using the 'Fleetwax' and guess what, a sooty transome. I do have a different question about your props, what are the pitches of them? Are all of them 18"? Thanks, Mark

I installed mine 18in from the inside of the transom and the thruhull flange at the edge of the water in order to get the hose under the locker floor. I also had to use a 45deg. elbow(Centek).The engine sounds a lot quieter(no water splashing) Next trip out I will let you know the results. Pierre SHUMKA #899 #899 2 cabin Pullman
