Re: honda 15 hp water pump!
Bite the bullet, that is a Honda dealer item and not really all that expensive, about $20.00. Yes, it is in the lower unit. Fairly straight forward unless you have cross threaded bolts like I did on one of the 4 bolts,(broke it off and had to drill it out ugggggg!) and also on the shift linkage that runs down the leg. This was the first change in about 14 years so good service on the engine. If they come out easily, then you are talking about 30-45 minute job.
