What is the difference between inboard and outboard motors? Here are the main differences, pros and cons between these boat motors.
- -An inboard motor is an automotive engine that has been adapted for use in a boat.
It is mounted inside the hull with a driveshaft that goes through the bottom of the hull to attach to the propeller at the other end.
- -Steering is usually controlled by a rudder that is behind the propeller.
- -Better fuel economy
- -More maintenance at higher cost for that maintenance
- -Cheaper to replace parts
- -More powerful
- -Because the weight is farther forward, the inboards are more stable
- -Esthetically, looks better because the motor is mostly hidden
- -Reduces drag because it is not protruding upward
- -Tend to be heavier and slow down the boat
- -Difficult to repair because of location
- -Basic cost is usually higher
- -An outboard motor is portable and self-contained.
- -The engine, gear case and propeller are usually attached to the rear of the boat.
- -Steering is controlled by swiveling the entire engine which directs the propeller thrust.
- -Easier to operate
- -More flexible (can usually be taken completely out of the water if needed)
- -More room in the boat with the engine hanging off the back
- -Removal for replacement is easier
- -Cheaper than an inboard
- -Minimal vibrations
- -Esthetic appeal is lower because it is all in view
- -The prop is not very deep in the water which could cause a bumpier ride
- -Filling up the gas tank may be difficult as it is usually in an awkward position
- -A sailboats balance can be compromised with a motor that is too large
