Re: Exhaust waterline question?
Some boats, mine included, partially submerge their exhaust port under full power. It is not an issue as long as the exhaust hose has an adequate riser, which it should. On your boat it may be that you are carrying too much weight aft causing her to "squat" under power. I seem to recall a lot of C&Cs have their exhaust ports at the very bottom of their transom.
As for fuel consumption, you can expect to burn somewhere in the neighborhood of 1/2 gal per hour. If you have been motoring as much as you say and your fuel gauge hasn't moved, you might want to confirm that it is working. I don't have the luxury of a gauge so I use a dipstick which leaves no doubt as to how much fuel is onboard!
