Fuel economy

I have a Mac 19 with a chunky Suzuki DT 40 C 2 stroke outboard. It has been recently serviced so I took the Mac out for a leisurely 5 knot trip on the Solent this weekend. I was hoping to get the sail up but alas not enough wind, but I had already filled the ballast tank, so I motored across from Southsea to Bembridge a trip of about 6 miles. To my horror I consumed 7 litres of fuel in 5 miles :o . Surely that can't be right can it?????
Another really annoying thing about this engine is that the back eddy's force dreadful carbon monoxide fumes into the cockpit. I was going to setup a soffit board across the transom with a rubber sheet hanging from it which I could cut around the outboard to seal the cockpit from the outboard, but I wonder if the fumes will just creep over the top. Has anyone else experienced this problem and do you have any suggestions.

Thanks

Eamonn.

Re: Fuel economy

shocking... but not. Old strokers and full ballast can suck the old cans dry alarmingly quickly. Out nissan 50 can be a thirsty beast at times.
You should get away quite easily with a 25-30hp 4stroke I'd of thought?
SOme folk do that with their 26s too to good effect.

In theory, there is no difference between theory and practice; In practice, there is.
