When I recently bought my 1989 2001, it arrived to me with 293hrs...I've only used it 4 times and my usage consists of riding to a cove, throwing anchor and hanging out. I have done very little "cruising" and am very meticulous about turning off the ignition switch to kill the power and prevent the hours from adding up unnecessarily. Thursday I was out for a little while and the hour gauge was crossing over 298 which took me off guard since I know I haven't used it that long at all...maybe a total run time of 2hrs. Doing some research I read that the hour gauge isn't all that consistent with how long the engine has been actually running, but rather a combination of how long the ignition has been on coupled with the RPM's of the engine. I timed it myself and cruising around 22-25mph, my gauge was about 2:1..meaning in 5mins, the clock went 10, etc. On the previous trip on the water, I did push the motor a bit since I had just done a full tune up and ran it up to 35-40mph for a brief minute which would tell me it added more time to the clock by doing this?
Anyone have any knowledge about what actually causes this or the RPM threshold that it begins to tick faster? Some were suggesting 1750rpm? So at idle/no wake speed it should be more in line with true time?? A lot of the article discussed how low engine hours are a indication, but not necessarily an exact reading of the usage of the motor. Found this pretty interesting since we generally place more value on a low hour boat but that may not be all that important after all ??
