Typically, your outboard should be serviced annually or every 100 hours' use (whichever comes first) to keep them it peak condition and minimise the risk of faults occurring during the boating season.
Autumn is a perfect time of the year to have your engine serviced if you're not intending to use it during the winter months - we can carry out a winterisation process at the same time which helps protect your engine from corrosion in the cold and damp environment.
