Original Power

Original builds from 1985 started with a Universal 21 hp diesel. As the years went by, power increased with options up to 30 HP diesel. 

Repower Recommendations

The Beta 25 is a fine choice of power for this vessel. It produces the power you need for motoring and low speed handling, while also providing excellent efficiency. The Beta 25 fits the engine compartment with minimal or even no modification required. The Beta 30 is also available for those that feel the extra power makes a difference in their use of the vessel.
