2008 Mariah SX18 Bowrider powered by a 4.3L V6 190hp Mercruiser engine with an Alpha One sterndrive leg and only relatively low hours of use.

The Mariah SX18 is an 18ft bowrider with a beam of 2.3m and towing weight of around 1450kg. Her versatile, no-rot wood-free hull design allows the boat to perform exceptionally well in all conditions. This 18-footer has volume and buoyancy, and while it isn’t especially wide at 2.3m across the beam, it has high sides and a deep bow that collectively sheds water and prevents slop splashing aboard. The full, wrap-around windscreen as well as a quality lined interior add to the Mariah SX18’s appeal,  and you’ll find her extremely good value for a quality imported 18ft bowrider.

A composite, timber-free, contemporary construction method is used to build the Mariah range. This versatile, no-rot wood-free hull design allows the boat to perform exceptionally well in all conditions.

This SX18 is in excellent condition and has just been serviced for the summer ahead.

Both the vessel & trailer are NSW registered to December & May 2021 respectively.
