Keel cooled/heat exchanger just thought she was running hot, temp reading 115 C if gauge is reading correct ?
Purchased boat 4 years ago been out of water till 2 months ago , she runs ok oil, fuel filters all changed but she has blown off Bowman 3419NP Keel Cooled Manifold Blank End Cap when gauge reading got 135C, she cruised 10 days earlier with no issues when gauge read 75C for a 40min cruise
