Perko Flush Pro

A dissenting opinion.
Parts left off a boat cost nothing, and create no service problems.

There have been cases of the plastic housing of a flush pro breaking. If your boat does not have a shut off valve directly attached to the through hull water intake, I would not add anything to the hoses that take water to the raw water pump.

The 1 inch, or 1 1/4 hose will flow more water than your bilge pump can move out of the boat.

I've read about that, some of the older models had that issue, but I've read that the newer models have resolved this issue. That's why I was wanting to get some real life reviews from owners here, to see if there have been any recurring issues. Your reasons mentioned above are part of why I want to make sure that the quality is there before I pull the trigger on one.
My shut off valve is just to the aft side of the through hull.

The claims that I've read about them breaking (and this is like fourth hand so take it for what it's worth) are that they break when trying to connect the hose in cold weather. If you leave a hose connected all the time (either via the through hull or a short garden hose extension piece), problem solved.

Definitely food for thought...thanks.

you sure about that? I'm pretty sure the modern GM pcm powerplants are 1 1/4". 1" is ford (which you may have on a GT40 boat).

I have the GT40 motor. I was trying to go off memory since I'm at work till tomorrow morning. I can verify when I get home tomorrow unless someone on here has a definite answer.

Oh GT40 is definitely 1". You are right.
