I bought a NOS 1990 15hp mercury last year. I used it right out of the crate and put 17 hours on it.<br /><br />From the first trip it did not pump water as good at the motor I had before. (1987 8hp merc) When I ran her for the first time this year she was not pumping water like she should.<br />I'm going to bring the motor in to have the water empeller replaced. Before I do so I'd like to get an idea of what it will run me. How much will this cost?<br /><br />Thanks,<br />11
