I know and have experienced all the pros and cons of gas vs. diesel. The one thing that will always push me toward diesel, in a boat where it would be appropriate, is the obvious volatility and explosive difference between the two fuels. I am willing to pay the extra cost in purchase and have the extra weight for that piece of mind. I know that if one is careful and maintains all well gas can be safe but not as safe as diesel. I consider enclosed boats with gas inboards potential bombs and I don't like sitting on bombs. Just my opinion and I am sure plenty will disagree.
I don't disagree. However, I am very comfortable with gas or diesel or even propane... because I'm a stickler on safe operations.
I would like to learn: What is the annual explosion rate for gasoline fueled enclosed inboard engine boats? There must be stats on that number.
