Article boasts 15 knots. I can attest to the 14 I mentioned.
Write up at launch of a gal that blessed our family for a period of time.
Most often it was semi. The '63 65 foot SS design had hard chines aft. With 6-71N they'd see 14 knots. Swap out to modern iron, and I think...
That's each engine. Again, I run twin 12-71 TA's at 750 HP, and at hull speed with the genny running I'm burning 25 gallons per hour combined....
Honestly, I wouldn't keep stressing the engines. That's a meaningful overprop.
Misinterpreting, perhaps poorly written. If you take a 750 HP engine out of a 61 footer and drop it into a 67 footer, you're going to get the...
Yeah, that's clearly what I'm seeing, too. An inch and/or working with cup...but not 3-4".
100 over is not a bad place to be. 25 to 50 over is probably perfect. But if you were 100 over, why in hades would anyone recommend 4 inches of...
What were you turning when they were 24??
How short were you on RPM? And how much pitch did you add?
Meh...get a good mechanical surveyor aboard, take a close look at hoses, fittings, nooks where oil didn't quite get wiped up, and run your oil...
Principle still applies. You'll be able to lope at 1400 RPM and make hull speed, burning around 15 per side. I do it at 68 feet and 750 HP 12's,...
That's the high end of the available HP from a 12v71TA. I think the DDEC version was 900+.
Maybe share that information as well as the prop dimensions before and after the change?
My perspective here...engine horsepower is engine horsepower, requiring the same amount of fuel to produce the same amount of thrust. If a 12-71...
Same can be said about our own country. Glass houses et al.
....come to discover that it's Parks staff running their own private charters...
Division of Parks for the City.
