Reply To: HD25 cyl temp

[LLOYD LAUTNER]

I don’t know what the actual temp should be on the HD25, but I do know they run hotter than their larger brother’s like TD’s and TN’s. You can hold your finger on the head of a TD while it’s running, but not so on the smaller HD25. As long as it is pumping out hot water spray with the exhaust instead of steam, you should be OK.
If you need new leather primer seals and instructions for your HD25, as you probably will, you can contact me directly at: lautharr@sbcglobal.net More good info at: pochefamily.org/outboard
