Amazed to see the great condition of the bottom end- has knocked thousands off the rebuild price for the customer. Also really impressed by the customer building the frame and lifting the engine for you guys. Tell him to throw some old carpet down on that timber sole though, and tape some builder's plastic on the walls. Same with under the engines- lay out some plastic between the engine bearers, throw a bag of sawdust on top and catch most of the junk. At the end, just gather up the edges of the plastic, into a bag and done. Sure, it's an older boat, but the easiest mess to clean up is the one you didn't make!

Don't forget to do the heat exchanger and after cooler. Not sure if DD had turbo aftercoolers. My buddy in the marina did an in-frame an a 8V92 due to lots of coolant in the oil. When they tore down the engine they attributed the coolant ingress to the liner o-rings. When they put the engine back together, the pan filled with coolant again and destroyed the new engine. Turns out while the o-rings were definitely bad, most of the coolant was coming from a corroded heat exchanger. They really should be done every 2 or 3 years. I had Cummins QSC500's and did the heat exchangers and aftercoolers every 2 years.

@@HammondOfTexas0 If it was a displacement hull, one non-turbo engine would push it along at 7 or 8 knots without breaking a sweat. The problem is when you want your big yacht to get up on a plane and go a little faster, it's going to cost you a lot of fuel and wear and tear on your engines. They get the crap run out of them in that application. It's double trouble, all you need is buckets of money.

Definitely give the heat exchangers a good look, especially the oil coolers if they're using raw seawater. A few pinhole leaks there can cause a cascading failure down the line. I just had my coolant heat exchangers checked and both were unable to hold 7psi pressure without leaking. Explains why she was losing coolant slowly.

[@arthouston7361]

What a blessing you are to people like this. I left the shop environment in 2000 with the intent to fly for MAF. I remember that the Detroit was a special animal in the engine zoo. I bet that many younger mechanics know nothing about this type of engine. Does this new boat owner have any recourse with the seller?

According to your views, it looks like you need to start taking on more of these boat projects. Great video though it makes me appreciate my 36 foot tiara Sportfisher. I’m in the process of replacing it 454 Chevrolet’s. The entire floor comes up and I have more work room than I could ever desire. It is a hassle having to go up and down the ladder out of the engine bay, though. Great leg workout.

Glad it turned out for the better. Good luck going back. I like others that have commented am way too old to be doing that kind of work but remember my one foray at marine repair on a Detroit for a friend on a Hatteras and it was terribly tight.

[@stevehetrick2676]

Idea,,,, get yourself a couple pieces of 2 foot squares of carpet or rugs. You can use them to kneel on, or lay on when working under the engine when your putting it back together!!! They will make it just a bit more comfortable when working long hours. Just this 69 year old farmer's opinion , i have been using rugs for close to 20 years now. 👍

[@Omegaman1969]

Same here, my Dad Always had a rolled up carpet with his tool bag, I use an old roll of carpet as well, keeps the cold off you aa well.

[@gullreefclub]

When I was still working on heavy equipment, farm equipment, and boats I used had a deal with a carpet company to buy remnants / scraps that were at least 2 feet wide and 3 feet long. Additionally when working on a boat like this one before I ever pick up a wrench the walls and floors are covered with plastic and then floors are covered with cardboard. Lastly something is placed on the deck on the path that everyone walks to get on/off the boat and to/from the engine room

[@Jethrosgarage]

It's the owner's boat, but I would have gone in with moving blankets and covered all the bulkheads, carpet etc, we put parts in tubs and trash bags to get them off the boat. Cheaper that paying to replace someone's carpet or wall coverings! We have alumimum, portable I beam rigs with adjustable legs that come apart we use to lift and rig, along with various short pancake rams and port a power pumps to lift them. Doing some big V16 Cats in a 180' yacht right now. How old is that boat? Google says Hatteras built them from '77-'87 in two different generations, must be newer as it would have had 71 series in the earlier ones.

[@BusGreaseMonkey]

The owner is in the video pulling the pistons out of the liners on his floor. He didn’t want to worry about anything in that area because he is going to replace the carpet, laminate flooring and wall paper after the job is done. Sure makes our job easier and it was a selling point to get me to agree to work in this job.
