Its double the amount of fuel you need to carry also another 200kgs in weight for the second engine your looking at adding another 320-350kgs to the boat. Double the fuel bill for the day.

I reckon its worth 20/25 mph and its not double the fuel, with twins you wont work the engines as hard so won't use as much fuel.

I believe when you take into account the extra weight and drag its the equivalent of a 50% power increase. More stability though!!!

The formula runs 63mph, tracks as straight as a die and chomps up all the typical solent chop, but can still return 3mpg taking it easy. And the sound is awesom. I like twins...next boat hopefully will have twins too.

2 has got to be the coolest, I would have loved a ride in the P23 with twin EFI's on it!

The Revenger San Marino which has a hull length of 25'' had a 200 efi on. The boat pulled about 52 mph. Most of the time it was driven between 45 and 50 so was running 5500rpm. Ive now got twin 225 opti. Ok so these engines are more efficient but normal running 45 to 50 and there only pulling 3000-3500 revs. It seems as though its using less gas but having never checked the MPG can't say for sure.
Top end well we don't have the right props but been told it should pull 75-78 when we find the right props (and driver)

What's the closest you can (reasonably) run a pair of twins with alien cowls?
