Hi,I have twin 8v71n's we burn about 10 gallon an hour at 9 to 9.5 knots.
You can't idle along with Jimmies for too long,they like to work for a living.
You have to give them a good blast at least every hour or so.
Not so sure you going to get anything south of 14 gallons per hour with 8v92T's.
Big boat,big fuel use.How many miles per year do you want to do?
If your not going too far it might be OK.
Super reliable motors though.I love them.
