It had a gauge when I got her. I made no modifications of any sort. Had some engine problems once otherwise it ran fine. Had it serviced (spring checkup), turned out the mechanic had inserted the impeller wrong and it overheated and shut down automatically. Towed into the marina ( was maybe 100 yds from marina) and had if fixed.
Not sure about stately. The Seilester is a 25' Coronado, someone change the interior layout before I got her. She was owned by Rose (Gibsons, BC) Then by me (Gibsons,BC then Tim (Vancouver, BC and then @Vaeredil and now ???? I still miss her.... a little small, a little slow, but oh so much fun sailing around Howe Sound
