My3sons, what gauges did you add other than boost and EGT? I noticed more gauges in the last pictures you posted.

Can you estimate how many hours these engines can give us when properly maintained and run? What are the max hours you guys have seen on them and how often you push them over 2300RPM?

my3sons, I am working on the setup. There is one thing I dont fully understand, the overheat switch in the exhaust manifold, is this 200DegF? It seems too low to me, there is coolant flowing in there? I just re-read your message, OMG 8000 miles! I did not grasp that the first time I read it...

And congratulations on the cleanliness of the engines.

Thank you Mark for the excellent information and for the welcome. I am happy to be here. Will try to do a very similar setup as yours.

I read that "old school required" because that's what I am looking for now.

Ah.. that made it clear thank you Bill. So there is one gasket and one o-ring on each side? About pressure testing, I am thinking of making a special hose fitting with air pressure gauge to test the whole seawater side pressure in one shot. Would disconnect the water pump output (to insert a...

Thank you for the fast reply. About cleaning the heat exchangers, I am worried that if I open it, it will mix seawater with coolant, or spill the coolant, or ... Because I am not sure how it is made inside. I did open the aftercooler and removed the core for cleaning, no risk there. So, about...

Bill, did you add any sensors to your engines, EGT, boost, fuel flow etc.. It would be nice to see some photos of the senders. I am thinking of adding a temp sensor in the exhaust pipe after water is mixed, I think it will be the best early indication of lack of fresh water. I am getting these...

Thank you Josh, I will check all items on the list and will report back WOT RPM as soon as we can have it cleaned. Bill, thank you for the pointers about the aftercoolers.

Thank you for your comments. Actually there were some circumstances including the owner is a friend of a friend, very good price, and the engines seem very clean (600 hours), that made me buy it without the full inspection (without hauling it out). I got a favorable dockside and engines...

Thank you for the fast reply! At sea trials it did about 20MPH at 2200RPM. empty tanks. They blamed it on dirty bottom. I dont know the prop pitch yet, will check asap. Thanks for the list of things to check at the 15 year mark. Will do... (OMG a lot! turbos too!) What are the signs that the...

I love the serenity of open waters.

Hello, my first post here! I'm buying a 2001 400 fly bridge with twin Cummins C450's. Getting it tomorrow actually. I have been reading a lot about these engines and already fell in love with them. I'm registered at BoatDiesel and sbmar. What are the speeds I should expect at different RPMs...
