Product Description

The Mercury 3.5hp portable outboards are designed from the start to be compact, lightweight and easy to carry.

We do not despatch outboards, we only sell outboards from our store.

On selling this outboard, the “Pre-Delivery inspection is performed by Qualified Mercury Technicians. This means the correct quantity of Mercury Engine Oil is added to the engine and the gearcase oil is also checked for the correct level. All grease points are greased including mounting thumbscrews. The outboard is then run for 10 minutes and carburettor adjustments take place if required. 

On customer hand-over, the outboard is started and run in test tank to show starting and running procedures. The Mercury 5 Year warranty begins on completion of the Customer Warranty Registration.
