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.

Old Merc Inline 6s - 1500, 1400, 1250, 1150
This is the second time I purchased from them. The kits are good quality, and impeller is durable. Pictures is the initial one I purchased from them two seasons ago. It had hundreds of hours on it, plus me accidentally cooking it for 3 mins without water hooked up to the engine - which is why I purchased it again. Given 2 seasons of use and my recent screw up it held up well.
