Heat Exchanger Flushing for R-25

[wa7pug]

We have 2017 R-25SC with the D105 VP. If anyone has added on flushing ports (inlets/outlets/valves) and have a diagram or photo, I would love to see a link to that ... I need to install flushing capability this winter in my boat .... Guess I could launch it in the lake and tool around a little but some might not consider that best practice. 😱
Thanks much! Doug

I am still looking to put a permanent plumbing option in so I can switch and flush ,,, but at least I can post the correct engine! My apologies ...
