I'm planning to purchase a 36-40' boat to live on in one of the marina's in Southern Calif.. I'm new to boating and need help with some basic information. I plan to go on couple excursions per month. One of the local islands is about 165 mile round trip and the other is approx. 50 miles. I know that gas engines are far less expensive and will run far less hours between rebuilds than diesels but what is the number of hours you can run the a gas engine with "average " maintenance? Also, what is the "average" for diesels?
Is there a rule of thumb for the average fuel consumption per mile for gas vs. diesels?
Any help would be appreciated.
Only ever seen one gasoline engine in a boat in that size range most are in much smaller boats (at least in the Great Lakes). Nothing wrong with gasoline engines but curiously in several hundred surveys of gasoline powered sailboats I have never seen one without significant ignition protection issues and engine/fuel compartment ventilation issues..
