David,
A bit more. The engine manual says change exchanger zinc at 50, 100, 250, and
every 250 hours after.

David,
On the exchanger is a label that says change it "monthly". I think that's a
bit much. I change it every 2-3 months. It is usually pretty used up.
It also depends on conditions where you keep your boat.

Hi Dennis- I changed the zinc when I pulled the heat exchanger several years
ago. You wrote “every couple months”. Really? How often does that pencil
zinc need to be changed? Dave

Changing the heat exchanger pencil zinc on my Universal 25XPB is usually a 5-10
minute job every couple months. This time the zinc stuck in the nipple. Access
is difficult with only 3 inches so their is no room to tap with "special tool
