On start up last summer departing Powell River our CC37+ Paikea started steaming as we motored toward Lund. A lot of bad things can cause that change! I powered back to near idle and limped back into PR. The belt looked fine, so then disassembled the impellor cover and replaced the impellor even though it looked sound. I figured the next easy step would to be make sure I am getting supply so I started working toward the through hull. Nothing but a trickle through any of the hoses. It’s funny how you anticipate the worst case. I removed the clamps on the through hull with the valve shut and pulled off the hose, and incredibly, could see a shiny head and two eyes. A sardine had taken a head first plunge into our intake! I opened the valve and a 3” fish shot into the bilge. The trip had not gone well for him, but it sure had improved on my end!
