The Whaler is a 1961 16' Nauset. 1st time doing an impeller change since acquiring the engine in 2014. I got the lower unit off, no problem. Pump housing is off. But... I cannot get the impeller off of the drive shaft. I am afraid I'll damage something if I pry too hard! Any tricks? Eric 1961 Nauset 16

Look at the demonstration at 1:46 on this video: https://www.youtube.com/watch?v=6WZMA...WZMArnU48c Soak it with PB Blaster. Edited by Weatherly on 12/27/14 - 11:24 AM

Look for Seahorse's advice on how to notch the relief valves to prevent static water seizing the thermostats. You may also want to check and/or replace your anodes.
