MFS25AJETETL
Marine Specialist Insight: The Tohatsu MFS25AJETETL (MPN MFS25AJETETL) is the ultimate shallow-water explorer. By replacing a traditional propeller with a high-performance **Jet Drive**, this motor allows you to navigate rocky rivers, sandbars, and shallow flats where propped engines simply cannot go. Built on Tohatsu's proven 3-cylinder EFI platform, it delivers the **25 HP powerhead output** (resulting in approximately 25 HP at the jet pump) required to plane heavy aluminum skiffs in inches of water.
Go Where No Propeller Can Follow
The Tohatsu MFS25AJETETL (MPN: MFS25AJETETL) is engineered for extreme shallow-water durability. Featuring a **Battery-Less Electronic Fuel Injection (EFI)** system, this 3-cylinder 4-stroke engine provides incredible torque and instant throttle response. Because there is no propeller extending below the hull, the risk of striking underwater obstructions is virtually eliminated, making this the motor of choice for river anglers and backwater explorers.
This model is fully equipped with Electric Start and a high-output alternator to keep your batteries charged and electronics running. The "ETL" configuration includes a 20-inch shaft length (designed for use on transoms specifically set up for jet heights) and a multi-function tiller handle that provides ergonomic control over shifting and throttle friction. With Tohatsu’s unique intake design, the MFS25A Jet delivers a smooth, powerful stream of water for maximum thrust in the skinniest conditions.

Frequently Asked Questions
1. How does jet horsepower compare to prop horsepower?
The MFS25AJETETL uses a 25 HP powerhead. Because jet pumps are less efficient than propellers, the actual thrust delivered is approximately equivalent to 25 HP at the jet nozzle, making it perfect for light-to-midsize skiffs.
2. Can I use this on a regular boat transom?
Jet outboards require a higher mounting position than propped outboards. You typically need a transom that is 6-7 inches higher than a standard 20-inch prop transom to align the jet intake correctly with the bottom of the hull.
