I just got replacements for my heat exchanger, wondering if they are anywhere else.
If so, are they the same size as the H/E?
I know I need to change the prop shafts and transom plate.

The U cooler takes a smaller size. Maybe 1/4" NPT, not positive. |

The camp part for the u cooler is E-0. Being stingy, I just order the pencils and reuse the 1/4" NPT plug. If the old one snaps off - two things to note - 1) that zinc was in too long, 2) use a small torch and you can melt out the old stub. It you need to chase the threads, I believe they are 1/4"x20 |
