Johnson PO15 diy water flush adapter?

[Brian Grigsby]

Hello.  Before I hit the water for the first time with my PO15 I was wanting to run it for a bit.  I seen a  U Tube video where a guy ran it without the prop and was forcing water in lower unit inlet for cooling.  Does anybody have any ideas on how to “force feed” water for test running on the stand? Thanks, Brian.

I’ve used garden hoses and fountain pumps on some motors,
but you have to get creative on how to attach the water supply
to the motor’s scoop. I made a saddle out of wood on one motor,
clamping it one with big hose clamps.

Prepare to be boarded!
