Brand new to the motorized boat world and a question I have had is "what is the general threshold for a high hour motor?" I know this is somewhat subjective as it is on vehicles but I generally assume this on a car to be 175-200k miles. What is the point on motors where expensive problems start to come into play? And the other question is how do people track hours on a motor? I'm guessing there isn't a timer attached to the motor.
