I often wonder if you took a life span of lets say 12 years, which boat is cheaper to own. A gas or a diesel. I know there are many variables. Distance traveled , price of fuel, initial purchase price. So here is how I see it. A diesel will get anywhere between 10 to 40% better miles per gallon and diesel is usually a little cheaper. I figured on my boat this would save me $1,500.00 per season. That’s a good thing. Also my boat would cruise faster and would perform better around the dock. I will also admit my type of boat 370da just feels better with diesels. But I asking what is cheaper to own and use.
The days of diesels lasting thousands of hours is very questionable. Diesels these days are small cu/in and put out a lot of power. I see way too many diesel boats with new engines installed. When things wrong you are in for really big bucks and long down time.
If you own a gaser like me 7.4’s You can probable figure on heads at around 800 hours. And new blocks at 1400-1800 hours. That’s as bad as it gets. For $5,000 you got a complete reman engine. I like the knowing my engines are easily replaced in just a few days and hell if you have to just put on a credit card and go boating. All other components on both engines need standard repair or replacement { pumps, manifolds, filters, etc. } . Parts for my engine are everywhere even ebay.
If you pop a diesel your going to be making a lot of phone calls.
Your going to pay heavy up front for a diesel boat but you will get a lot of it back when you sell and selling is going to be quicker. Also when you get around 22,000 lbs a gas engine just might not be a good match up.
I would love to own a diesel boat but if I’m paying $50,000.00 more I want power that is bullet proof and little to no headaches. I just don’t see that any more. IF you take the same boat one with gas and one with diesel my feeling is in 12 years you spent less to run the gas boat. I’m sure the diesel owners will have something to say about this.
