Incorrect motor listed. Far smaller impeller than what's in the 6 horse johnson.
Size: For 5.5HP 6HP 7.5HP
It seems to be of good quality. However it does not fit a 6 horse johnson as it states. Therefore it will not pump water or function for my purposes. It was a waste of money.

10 out of 10
The must do service package. This is a "fits multiple" kit so youll have some extras. The kit also includes the lower unit gear oil seals, which is awesome. I always trust quicksilver to be durable and a great value for the money.
