1998 DT200EFI, On a heavy build 6.5M RIB with my family and a days picnic gear etc and I get about 1.25 to 1.5l per nautical mile crusing at 25 to 30Knots.
With a light load I've seen 52Knots, and 46knots with 4 adults on board.
But best of all, its light for a 200HP, and sounds awsome.
Mrs Nasher still won't let me to keep it in the house though!
Do need to keep an eye out for corroded electrics connectors. And make sure the fuel is very well filtered and completly free of moisture, as the injectors are apparently very fussy about what they squirt.
RIBBED For extra pleasure.
