All of my boating is done in Poole in Dorset, its a family boat and we rarely ever go on long trips out of the Poole kind of area. The boat would be used for about 4-5 hours a day on and off, so it would never really be making high speed journeys for long durations of time.
Think I might have to look towards 4-strokes.
Cheers for your help Gary, any other comments are greatly appreciated.
Cheers
Chris
