have this engine on a heavy boat i have a 13inch prop which gets me 24knotts and 5250 wot.
I am thinking about getting an 11 inch prop to get closer to the top end of the wot range.
with the cost of fuel i wonder what is the sweet spot i have read about. i guess i would like an idea of the best fuel economy rpm . the boat planes at around 12-13 knotts
what fuel usage in litres can i expect at around 4300 rpm
what do you think elvin or others
thanks for any help
