BF 80 AK1 LRTU Engine Technology and Key Advantages

PGM-FI electronic injection ensures easy cold starts and consistent power output. Maintenance requirements are lower compared to carbureted alternatives. A 25-liter internal tank provides comfort for medium-distance routes.

• 3-Cylinder OHC PGM-FI Engine (1496 cc, 4-Cylinder): PGM-FI electronic injection ensures easy cold starts and consistent power output.
• Long Shaft (508 mm (20")): Perfect fit for the transom height of small and medium-sized fiberglass or aluminum boats — the propeller operates at optimum depth.
• F–N–R Gear System: Forward, neutral, and reverse — full control during narrow space, dock, and marina maneuvers.
• Electric Start: Instant activation with a key or button — comfortable and quick starting.
• Electric Trim and Tilt: Adjust trim angle with a button — optimizes fuel efficiency and speed during cruising; allows motor to be fully raised with tilt.

Frequently Asked Questions

How fast can a Honda 80 HP engine go?

The speed with 80 HP depends on the boat size and load. Approximately 25–35 knots can be expected on a moderately loaded 4-meter inflatable boat. Actual speed is directly related to boat type, propeller pitch, and load capacity.

What advantage does the PGM-FI system offer in this power class?

PGM-FI electronic injection offers easy starting in cold weather and consistent power output. It has lower maintenance requirements compared to carburetors.

Is a 25-liter internal tank sufficient for daily use?

At 80 HP, consumption at medium RPM is expected to be approximately 14.4–17.6 L/hour. A 25 L tank provides a cruising range of 3–5 hours. An external tank connection is recommended for longer routes.

Which boat and inflatable boat brands are compatible with the BF 80 AK1 LRTU?

Honda outboard motors are compatible with the vast majority of Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local brand inflatable boats due to their universal transom clamp system. The only criteria are your boat's 508 mm (20") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
