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.

Best bang for your buck kit!
Can’t beat the price by any means. Total rebuild kit for Mercury 115 outboard for less than half the price and all high quality parts nothing cheap about this kit at all except the price. Highly recommend
