OEM is always the answer
No reason not to go OEM for this! Came with every possible gasket and seal I could need. Specifically for my Alpha One Gen 1 it took maybe 25-30 min to completely install. While you’re there check the base plate for wear and the other surrounding items like your water tube. Rather keep the lower unit off for an extra day to get another part than a catastrophic failure.

Husbands things
My husband bought this. I don’t know much about it but he has zero complaints. He bought it for a boat. He has fixed up 2 boats, sold one & we kept the other. So he apparently knows what to buy & how to use it.

Outboard is Cooling
The repair kit arrived on time as scheduled. The kit contained everything needed to replace the Mercury 175 OptiMax impeller. The engine is cooling now and we are back on the water without issue. Easy replacement.
