Frequently Asked Questions (FAQs)
Q1: What is the primary advantage of this motor’s lightweight design?
At just 51 lbs, the MFS5CL is significantly easier to lift, carry, and mount than many competitors. This makes it an excellent choice for sailors who need to frequently move the motor between a dinghy and a storage rack, or for anyone who boats alone and needs to manage the weight themselves.
Q2: Is this motor suitable for saltwater use?
Yes, the MFS5CL features Tohatsu’s advanced corrosion protection, including a special anti-corrosion paint process and sacrificial anodes. However, as with any outboard, proper flushing after use in saltwater is essential for long-term durability.
Q3: What is the approximate runtime on the internal fuel tank?
With a 1.1-gallon tank and very efficient 4-stroke operation, you can expect approximately 1 to 1.5 hours of runtime at full throttle, or several hours at trolling speeds. For longer excursions, the motor can also be connected to an external fuel tank via an optional connector.
Q4: Can this motor be used as a backup (“kicker”) for a larger boat?
While it can provide emergency propulsion for a lightly loaded smaller vessel, the 5 HP output is generally not sufficient as a dedicated kicker motor for larger boats (e.g., over 18 feet). For that application, a motor in the 8-15 HP range is typically recommended.
Q5: What maintenance does this 4-stroke outboard require?
Routine maintenance includes engine oil changes every 100 hours or annually, gear case oil changes annually, and spark plug replacement every 2 years or 300 hours. The freshwater cooling system and internal anode should be inspected periodically. For detailed schedules, see our [4-Stroke Outboard Maintenance Checklist].
