A few years ago a customer of mine asked if I could take his boat from our local Marina to a harbour and recover it on a trailer, it had a 275 verado outboard on the back. At 23ft long it was a nice package with all the posh gauges and a system matched flow meter, as i left the marina at a jogging pace the meter showed 3 gallons an hour which I thought was very reasonable for such a package. After about 10 mins I opened the throttle fully it projected me to over 50mph which in water terms is extremely fast and the flow meter 28 gallons an hour. Bonkers and any marina in the uk you will see boats with two fitted. Makes Morgan motoring look very cheap. Must dig out my oars.
