    'CLUNK' under load, '93 Evin v4 140hp looper, good dogs, wrong lower unit?

    Put on an older, used LU on my '93 140hp v4 looper, fine on muffs and in the water in forward at idle, but then clunked loud and hard about every 2 seconds at forward slow, and about every half second with a little more throttle. Didn't do it in reverse though. Seemed like the dogs hopping so...

    140hp lower unit forward bearing carrier stuck

    I have a 1993 140hp that leaked salt water into the lower unit (and I didn't check it). When I dropped the lower unit to see why it wouldn't shift into reverse, things were pretty ugly. I got it apart down to the prop shaft and forward gear and bearing housing, at which point the manual said...
