Fuel consumption
My wife and I just bought a Carver 1999 406 aft motor yacht. It has twin 7.4 L Crusader gas engines.
We are trying to get some kind of a range of fuel consumption at different rpm levels.
Any ideas please.
Thanks, John

Re: Fuel consumption
The 406 is a huge boat, tons of room - a great Carver design. However the 7.4 is the smallest of the big blocks and was the base engine. Boats in the 39-40ft range are on the verge of needing Diesel engines or at least the 8.1 blocks. IMHO the 406 is grossly underpowered to run at planning speed with the 7.4s BUT will still be efficient at hull speeds. You should see about .75MPG at 8kts. My buddy has the identical boat and this is what he runs. You need to be quick on the controls when docking because of the windage of your boat as it is virtually a sailboat. You will use quick jabs of throttle with forward and reverse to dock it without thrusters due to where the torque is in the RPM band of the 7.4.
Great boat though, and the smaller engines make servicing a dream, lots of room in the bay.

Re: Fuel consumption
Even our 3697 with 350 Crusaders could use a bit more juice, but it runs nice and at least gets out of its own way. I have no problem being in weather with it.
You did not say where you boat, but listen to weather radio and if you can, install a honkin radar so you can see weather approaching from afar. Heading into the weather is not so bad, if directly into it. Any other angle will leave you concerned, and a following sea will just push you all over the place and even get the boat sideways once in a while.
Point being, great boat, but avoid weather at all costs. If you ever grenade an engine, go diesel. Biggest ones you can shoehorn in.
