    That's cool that they're using diesels in their aircraft. That awesome you were able to give them a project to gain experience working on the harder to find and rare equipment. Altho, IH may not be that rare in your area. They're rare in my area of SC.

    They started out making flat four aircraft diesels and then went to the inverted design to narrow up the engine. The original flat four design was on display at the Oshkosh homebuilt aircraft show. Good to see they are keeping pace and not letting the diesel designs die.

    The last time I check new entry-level aircraft prices, they were around $150,000 to $180,000. Add a diesel, if it were an option and that aircraft doubles in price. Diesel engine for aircraft use hasn't proven themselves like gas and jet engines. Until then, any aircraft flying one would be...

    I was a pilot and aviation line service tech. All the piston engine aircraft I flew had dual magnetos, dual spark plugs, and dual plug wires. I had a good run-up in a C182. Everything checked out. I taxied to the runway and was cleared. I was between 750 and 1000 feet off the deck and climbing...

    Yeah, the marine spec Cummins has two options, highout put alternator, and engine driven marine water pump. The only other options are the power levels mentioned above. The Detroit diesels go back to the '50s in boats. Those are really heavy beasts and leaky. I talked to a Detroit tech and he...

    That 2.8 is a nice engine. It's a higher-revving engine than the more commercial engines. There's also no marine manifold or turbo for it. I would have to have that to keep the engine bay cool. Computer-controlled is an issue as well. In the event of electrical failure at sea, I need an engine...

    Anyone know you can get 4 and 6 BT engines on Alibaba? The 4 is around $4000 for an industrial engine and the marine version is around $4500. The 6 is $4500 to $12,000. Who knew?

    This is the post I made over on the Downeast forum where a lot of guys are commercial fishermen and know about a boat's systems. Some of this may not make sense but I reposted it here to help others that may come here looking for the same help I was. This was after talking to a Cummins rep and...

    He started out stating he was building a sailing vessel. After realizing his sail plan wouldn't allow him to sail into the wind or close to the wind. He started calling his boat a motor sailor. Motor sailors are a thing, but the sails are there to assist with motoring to reduce rolling and fuel...

    His prop control was designed to be used on a powerboat with no transmission. The prop would feather in a way to give both forward and rearward travel with the engine set at the best rpm for torque. He changed the hub orientation on the blades when he designed his prop blades. I don't know if...

    I get what you're saying. Yes the designer is going on max HP. The 150hp Cummins has the torque curve peaking at 1400 rpm and dropping off at roughly 1650. Torque is in the mid 300ftlbs range IIRC. You're right, I need the torque for the prop and the accessories mounted to the engine. The...

    My engine won't require marine exhaust and the other associated parts and plumbing to bring in water from outside of the hull. Also, no turbo so no worries there. My engine and transmission will be keel cooled and dry-stacked. The alternators will be ignition protected marine units. This isn't...

    Thanks. I found out yesterday that I have a new Cummins dealer right behind my house.

    Thanks. I want to make sure I am using the right parts for the best fuel burn and reliability for the power level I need.

    Everything I posted was directly from my Cummins manual. Things were different in the '91-'94 year range. I think it all had to do with the upcoming emissions changes. There's another manual for the '94-'98 engines. Since there are two manuals with '94 engines listed, I think they underwent a...

    Thanks for responding. I don't have an engine yet. I'm trying to decide what would be involved with rebuilding a truck block to the marine specs for my boat. ANYONE READING THIS, PLEASE KEEP IN MIND THAT THIS PERTAINS TO THE 1991-1994 4B/4BT/6B/6BT ENGINES. OTHER YEARS AND APPLICATIONS MAY BE...

    I want to add a little info I have found. The non-turbo engines run 19:1 compression and turbo engines run 17:1 compression. Where is the compression difference, head design or piston design? I think the piston design would be different because they are easier to manufacture than a cast steel...

    There is an elusive 5.9L 6B Cummins that I am looking for info on. It is a non-turbo marine version with an HP rating between 150-173 made between 1991-94 with a max RPM of 2800. The automotive and marine versions are identical in appearance once the marine exhaust manifold and the marine water...

    That's why I would prefer a marine starter. I know the issues with gasoline. I always popped the hatch or tilted the dog house open while running the bilge blowers before starting the engines. It wouldn't be as big a deal with diesel, but with my luck, big BOOM! :rolleyes:
