The relatively early demise of my gimbal bearing (175 hours) got me thinking this question.<br /><br />My bearing was wet for about 1 week that may have contributed to the situation.<br /><br />I gave it about 8 pumps at the end of every season. <br /><br />The boat had 63 hours when I bought it and was 2 years old. I believe that the first owner maintained it well, but don't know for sure.<br /><br />When I bought my new gimbal bearing, the parts counter guy said to give the new one 25 pumps and that was the reason mine failed -- I didn't grease it enough. He says to give it 20 to 25 pumps at the end of each season and wipe out all the old grease pushed out.<br /><br />BTW, I only use the Merc green gimbal bearing grease.<br /><br />So, did I under-lubricate? Is 20-25 pumps too much? This is all assuming a 50 to 100 hour season.
