The Mercury 3.5 hp 4 Stroke Outboard Motor

The Mercury 3.5 4 stroke outboard was my second outboard purchase.  Back in 2010 when I was just getting started in boat fishing I wanted a lightweight outboard to power my inflatable boat and get me a mile or so out to the fishing grounds off Skinningrove, where I was living at the time.  I recall paying £580 at the time for the engine. I already had a Mercury 9.9 2 stroke but wanted something lighter and easier to manage as I would be setting up the boat solo.

The running in process was as follows:

First hour:  Run engine at various speeds up to 2000rpm or half throttle.

Second hour:  Run engine at various speeds up to 3000rpm or three quarter throttle then go full throttle for one minute in every 10.

Next 8 hours:  Run engine at various speeds as required but avoid continuous full throttle for more than five minutes at a time.
