Agreed and thank you Philip. As for the the impeller I was just stating they were in good condition so it wan’t the problem, however I do feel they should be running a bit cooler from others experiences (however they were in different lower weight boats). I’ll definitely service them this winter and get it all cleaned up and tested. Upside is they were flushed every Fall and spring when they were laid up and not much growth where they were in in the N. East. However, yes way overdue on pulling them, pressure testing and cleaning etc. Seaboard has a great reputation and is not far for me for work I can drive up there so that is the plan.

Much appreciated – Mike

They will hit max RPM at 3000 to 3050. Starboard will climb to 181 degrees and then back down to around 178 and hold, port to 178 and hold back down to 176. I usually don’t put it on the pins for more than a minute.

I purchased the boat from my father who regularly serviced the boat but he has never pulled the inserts or the coolers. The boat is a 2009 with the 550 cummins. It only had 340 hours in the Northeast and is now with me in Southern CA. The boat was in the water from late May to early October each year since new. Pulled flushed and winterized, then put in indoor storage. When I changed the impellers a month ago the old ones didn’t even have a crack in them. Not what I’m used to after running Volvo’s and Cat’s before. I love these engines but I am far more anal than my old man and do most maintenance myself. However I won’t be pulling the coolers myself.
