Alamarin-Jet was founded over 40 years ago in 1976 by Finnish engineer Mr. Jussi Mäntylä

Jussi Mäntylä’s hobby was sport fishing along the rocky coast of the Baltic Sea, of course this environment is not well suited to outboards or sterndrives and he realised that a water jet was required. Having investigated what was available to purchase he decided to develop his own water jet…and Alamarin-Jet Oy was born.
