I have a 1986 Mecr 140 Alpha 1 and I hear a clanging sound from the lower unit- not sure if it is coming lower or upper. What could this be? Mechanic (not sure if trustworthy) I took it to said this sound isn't normal and thatit might be gimbal bearing or u joint or even something worse. He gave me an estimate for joints,bearing and new impeller plus labor of $500- is that good? <br />Is there any way I can diagnose myself without taking lower unit off? What are the signs of a bad gimbal and u joint and what does a bad one look like? Easy to do myself? Does the lower unit have to be fully lowered before you take it off? Do you have to use a hoist as Clymer recommends?
