Throwing a question out to see if a better way to make sure cooling water stays flowing at 100+ mph. I have a 27' Cougar cat new to me & the way its plumbed makes me wonder if at speed it cavities the sea water pump as there is no scoop on the hull to direct water up in to the opening & the water pickup from the XR drive is plumbed directly in to the intercooler then overboard. Should the drive inlet water be tee'd into the sea strainer as well??
I pickup the motor water with the outdrive, to the water pump and into the motor.... and the intercooler is plumbed to a hull pickup and through a stainer, no pump..
mine is plumbed the same way, i put a -10 pickup and sea strainer in for my intercooler. Will be installing the same setup for my engine as well.
took my brand new motor out of boat and disassembled after one weekend at parker with no sea strainer and was suprised at how much sand made it into the block that quick. Also caught a plastic bag on my lower unit and shut the boat down before it got over 150 degrees. A pickup off the bottom of the boat wouldnt of let that happen.
