When shopping for the appropriate marine gear for your boat, do you know which type you need?
An inboard marine gear is mounted inside the hull of the boat below deck, and the drive unit is mounted on the stern of the boat with a drive shaft encased in a boot, which goes through the stern of the hull. Such engines are standard on most runabouts, deck boats, and small cabin cruisers. The engine can range from a small 4 cylinder, 100 HP (horsepower) all the way up to an 8 cylinder, 400 HP (horsepower), with several others in between. The out drives are either single propeller or dual, counter-rotating propeller types and are mounted onto the transom of the boat. The dual prop tends to provide more 'traction' and power, particularly in accelerating from a stop. The out drives can be tilted up or down to compensate for differing boat load conditions and, since the whole out drive turns from side to side, steering and maneuverability are greatly enhanced.

An outboard marine gear is mounted onto the transom of a boat. Since the whole engine and drive train is a single unit turned by the steering, they provide excellent maneuverability.
Outboard engines are manufactured:
Outboard engines are manufactured:
- 2 stroke, which must burn oil mixed with fuel;
- 4 stroke, which burn gasoline by itself; and
- a variation of the two called Direct Fuel Injection (DFI), which is a hybrid.
