Quick follow-up question. When the boat was inspected the marina told me i'd need a new impeller. Is this the same part as the one you guys referred to in the previous posts? Also, the marina worked on the alternator a few days before the water pump issue surfaced. Is there any possibility the mechanic could have done something to the pump brackets when he worked on the alternator? The timing of the issue seems a bit fishy.
A few other questions. Do you have a diagram (drawings) of the engine? I’d like to make sure the issue only extends to the water pump. The drawings would be a good way to confirm this hypothesis.
Thanks for your help.
