Hej.
Jeg har tidligere spurgt omkring dette emne, men nu har jeg mere præcise oplysninger.
Motor Mercruiser 5,7 liter v8 karburatormodel 270 HK (s/n OK199586).
Drev Bravo II udveksling 1,5:1,0 (s/n OK238216)
Bådvægt ca. 3 tons.
Hvilken propel (alu) vil være den rigtige - økonomi er vigtigere end fart.
Hvilken omdrejninger skal motoren kunne opnå.
Er der nogen der ved benzinforbrug ved forskellige omdrejninger på motoren.

Hej,
I also have a 24 Family and it is equipped with a 2002/2003 year model 250 hp 5.0 Mercruiser with carburettor. I think this was one of the last of the carburettor engines.

The drive is Bravo 2 and the prop is aluminium 48 18614A40 19P (Diam 18 1/4", Pitch 19" ?).

With this setup I think I have a lot of torque and power to accerate very quickly to get the boat on plane as efficiently as possible. The large prop also gives nice grunt for manouvres in docking areas.

I usually cruise between 22-24 knots and at this speed the engine revs at around 3600 rpm.

With mixed speeds and loads, my average fuel consumption is about 1,8-1,9 litres per Nm.

How does this sound to you?

Kind regards, hälsningar,
