<div dir="ltr" data-setdir="false">Tim, these pictures are from the R300 port stern thruster taken during the IS Beaver Island Expedition after the thruster quit working after a two-mile submerged transect. It had been about 2 years since they were torn down but only an estimated 18-20 operating hour on the unit. The thruster was hydraulically pressure compensated withe WD-40 and did spend 99% of their life sitting in my shop in Texas exposed to some high temperatures during the summers. They were used only in Fresh Water, primarily at the Lake Charlevoix Psub event and the recent Beaver Island IS Event.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Cliff</div><div><br></div>
