Hello there MM, Welcome to the iboats forum, you'll gain access to the impeller by disconnecting the lower unit. <br />I suggest you acquire a service manual for your motor, read it about 3 to 4 times prior to starting this procedure.<br />Good luck and keep us informed of your progress, there are lots of good folks here to guide you along should you get stuck
MM<br />Go to BassBoatCentral.com and click on Sherm's Tips. He has a good explanation of changing water pump. The advice on getting a manual was good advice as you will need it quite often.<br />Good luck,<br />Bob
