OVERKILL
$100 Site Donor 2021
That's from inside this guy:
Operated in fresh water exclusively. Sacrificial anode still in decent condition. It was not like this about 3 years ago when I changed the impeller last. Was getting in to it to change the impeller again, clearly, this isn't good.
The front section is the through-prop exhaust, back section is where the impeller sits, there's a tube that its housing mates with. Checking with the marina to see if that mid section can be purchased as a replacement part. The upper section is still mint, lower unit is in decent condition (better than the mid section).
