Ribcraft 4.8 - How quick?

[Robert1]

How quick is a Ribcraft 4.8 with a Merc 60hp 4-stroke EFI likely to go?

What would consumption be like for the boat? (I have a 55 litre fuel tank)

Thanks,

Robert

This should be of some help to you.

I had a 60hp yamaha 2-stroke and id use about 50 litres in a whole days ribing. about 5 hours on the water time. So about 10 litres an hour.

With your fourstroke that should be down to about 30 litres. Maybe a little more.

Nothing scientific, try the mariner website for that but the fuel consumption on a website does not reflect on the consumption with 4 people in the boat in rough water.

HI Robert

I had a Ribcraft 4.8 with a Mariner 50HP 4 stroke on standard prop etc.

One up i could get about 28Kts flat out in calm water.
Trim was critical though.

As far a fuel goes I worled on about 6 MPG curusing speed, say 20Kts.

On a normal "play day" of about 4-5 hours, tubing etc I used about 4-5 gallons of fuel.

Useage and speed will be higher on yours being a 60 but not much on useage as mine was not a EFI.

Hope this helps

Regards Gary

Hi Robert,

I have a Tornado Viking 470 with a Mercury F60 EFI - similar boat to the ribcraft.

I get a max speed of 34knots and a cruising speed of about 28knots. Fuel consumption is pretty good - pushing the boat quite hard I get 40nmi out of a tank (23Litres), if I take it easy fuel consumption decreases dramatically - 50 to 60nmi per tank

Robert,
Top speed one up in flat conditions expect 40MPH, Fuel consumption I can concur with DJL. Between 40 - 60 Nautical miles for a 5 gallon tank.
