less than 40 hours on this unit and the upper drive bearing failed cost $40 to ship and the unit was repaired (HOPE). vaction and summer stopped short, I'm lucky I can remove and replace the unit myself. labor costs would of been painful. requested a replacement water pump to compensate me for the loss but this was ignored. yea I'm nervious. bought a new mercruiser tramson housing last year and this leaked from day one (defective boot) so buy from japan.
