Marine Gas Versus Diesel Engines

Marine Gas Diesel Engines

Many discussions about marine gas versus marine diesel engines can be heard around the docks and raft-ups where boat enthusiasts linger.  Popular opinion and beliefs aside, there are some important facts to consider when weighing the pros and cons of a marine gas or diesel engine, especially if you are shopping for a new engine or boat and this issue is one of your determining factors for your purchase.

Here is some information about both marine gas and marine diesel engines:

According to BoatSafe.com, the average marine gas engine will run without major problems for about 1500 hours before it needs any extensive maintenance.  A marine diesel engine, on the other hand, will run about 5000 hours before it needs major repairs.  However, if the boat engine is not run regularly, the need for repairs will increase significantly.

The size of your boat makes a difference in whether or not to choose gas or diesel.  Boats over 16000 pounds (or about 35 feet) generally require the use of a diesel engine.  The bigger the boat, the harder the engine must work.  The build-up of internal heat in a gas engine with a too heavy load results in poor performance and longevity for a gas engine.

If you compare marine gas to marine diesel for sale, you’ll notice that the price of diesel fuel is cheaper.  However, that doesn’t always translate into lower overall marine fuel costs.  There are many factors that go into fuel economy.  The size and weight of your boat as well as the speed at which you drive the boat both make a big difference in how much fuel you will burn through.  This is primarily a concern for boats of the smaller to mid-range size. Bigger boats with diesel engines that are run at higher speeds may ultimately prove more costly when comparing the marine diesel for sale prices to those of marine gas.
