Fuel Consumption Mariner 150 Optimax

Just bought a Northcraft 6.3 m RIB with a Mariner 150 Opti. What can I expect fuel burn to be? The boat has a 83 litre tank and I am wondering how far it will take me.

I recon at best 83 Nm, but you'll not be able to resist WOT so 60

1.0 to 1.1 L / NM at about 4000 revs

I get 20Ltrs per hour @ 25 knots, then up to 55/59 Ltrs per hour a WOT which is around mid 40's knots.

keep a spare can on board!!

Thanks for the info. I was abit concerned that the tank was abit small and petrol is not so easy to find in some marinas so it's handy to know what range to expect.
