First starter never work. They warrantied it. The next starter lasted 2 months. FYI, I don't ride salt water. They warrantied it. The third starter I ran for a month before I had other engine troubles. Lucky the troubles were at the end of season (I know some of you the season never ends). So the Motor/starter sat in the garage for 5 months. Started rebuilding last month. I did not bother to check the starter while it was out, so once I put everything together...another failed starter. Original purchase was 3/15/15....so I missed the year long warranty by a month. Good riddance, I'm tired of rebuilding for a starter that should be relatively reliable. I've owned 9-12 different skis over 10 years, 2 starters have failed. A 88 SX Kawasaki, and the starter that SBT replaced which was a 93-97 Yamaha (20 year old starter I would guess)
#1 failed out of the box.
#2 failed in 2-4 weeks, locked up and hummed when connect to power
#3 spins freely and feels like nuts and bolts are being grinded, on power turns randomly with no torque.
