What I meant is, Engine RPM and vessel speed are not linear and they are not always the same. If there is current, wind, or waves the same vessel...
I understand how propellors are loaded as well as vessel speed is not directly related to RPM either. An Engine/vessel is propped for a 100% load...
Meeting with people in the marine business is the best way to go. Stopping by in person with business cards and brochures and giving them to...
The propellor curve that is published starts at 1200rpm's, not 600. I can tell you what the engine computers were saying was 3 and 3-4gph. Go...
Most diesels at no load, idle burn less than 1 gph. That is just running with NOTHING attached to it. No propellor, 0 load. You're joining 2...
It has not much to do with which engines, most all diesels sip fuel under 1,000 rpms. Most diesels at no load, idle will burn less then 1/2 gph....
What operating temperature are other Captains seeing on their Detroit Diesels when running in gear at 600 and 800rpm's (without running at cruise...
I know they ALL have a roots blower, but the blower is the same displacement as the engine it is on, so it does not produce any additional...
Various Factory Certified CAT, MAN, and Detroit Diesel mechanics over 25 years of experience as well as over 300 engine startups on new vessels...
Welcome to why I don't do business in Miami. It might be time to find a new marina. Nobody in Miami has any sense of urgency with anything....
What I was referring to with engines running cold is, in the US a lot of yachts will rarely see cruise RPM's..... You could let a DD 671TI-16v92TI...
I own a yacht management business in Fort Lauderdale and do quite well at it. You may have to take on some jobs that you would never do in the...
What exactly cools the Intake Air? The intake air is cooled off by an intercooler. The intake air coming out of the turbo is cooled by an...
That is true, however the turbo won't spin fast enough to produce enough boost to create additional horsepower until 1300 rpm's or so on most engines.
It does take a certain amount of airflow and power to turn the turbo, they do create additional power over and above that. Needless to say, I am...
You're forgetting one variable in your calculations. Engine efficiency will be much better at slow rpm's 1000 rpms and under because you are not...
It doesn't take hardly any extra time in the thick and thin of things to make a yacht with a good finish. You only have to have a good mold...
I understand that it takes power and fuel to turn a propellor. But the load factor still determines how much fuel is needed to maintain 600...
The speed of the boat at idle is part of the equation. The faster the speed at idle, the less engine load, and the less fuel needed for the motor...
