I was planning to run the acid through the exchcangers but looking at the 8v53 it looks like the core comes out pretty easily. Ther are 2 squares with bolts surrounding them on each side of the raw water inlet and outlet.One is bolted onto the other. Are they easily removed (usually) when the bolts...

I was on the first major trip with the new boat. I checked all the hoses for rot and weakness but missed the hidden fault. The transmission pressure gague hose had rotted the steel braid under the connector and let loose after a 6 hour cruise through hell ( squalls ). Luckily the man upstairs looks...

Does anyone know the shaft length for a 41C? I have 8V53 detroits. It is probably in the manual on the boat but I cant get there until Saturday.

Steve (67Hatt34c) got me wondering about bottom paint. I had no idea what was on it and was thinking I need to plan on repainting soon. I called the yard my boat was at when I bought it. I asked what paint they used last and they looked it up. The interesting part is they found it to be micron CSC...

I am thinking of putting a second set of horns on my boat. It's A 41C so it needs the very loud ( I believe 150 DB + ) horns which are just a bit much in the marina and the locks. If I put a second horn like on a vessel below 39 feet and leave the monster asrequired I should be both legal and...

My 1/2" copper has yet another leak and I guess it's time to replace the whole thing. The Lower station was removes so I can remove more than I will be putting back. I was planning on leaving the rub to the bridge since it looks fine and replacing the remainder from the reservoir to the block and...

I just bought a 41C a few months ago and once all the pumps, hoses and fittings have been attended to my next job is cleaning up the rusty messy engines. In my old life as mechanic I would just tear them out and repaint them but 8v53's are a bit big to put in the pickup and take them home so I was...

I can not post on the service questions part so I hope someone here will re assure me of my use of common sense. I am in the process of un doing a multitude of wrong doings on a pair of 8v53 detroits in a 1966 41C. The previous *&%$ who worked on it removed the engine mounted fuel filters. There...

I just saw online some parts for DD 8V53 turbo engines. I never heard of one in a boat but I wonder if it is possible to convert the old 8V53N to T at reasonable HP say 425-450 and make the boat run close to the 30 Kts a re power would get at a lower out of pocket cost. People with the 41C have...

I have an older (1966) 41C with a pair of 8v53 detroits that seem to run great but the previous owner let them go without maintenance and more. No oil dipstcks. 5 year old impellers. Lots of leaks and rust. I got a set of manuals from Detroit and ordered the manuals from Hatt but many things are...
