I am thinking of adding a strainer between raw water pump and heat exchanger to prevent broken impeller piece getting into heat exchanger. (did have such issue with the old volvo and I added a strainer with clear window to solve the problem.)
The existing tube on Beta is a metal one. I am thinking of using rubber tubes. The issue now is the size of the tubes. My engine is a Betamarine25 installed at the end of 2016. If anyone has this info please let me know. Thanks.
