Priming the air conditioner

[captd]

Andrew,
Back a while ago you posted a how to prime the air , did you not? Well I can not find it. On lake Washington you did something like what? Shutting it off and turning it back on acouple of times?

One post came up with the hose suction trick, which is better than what i use to do. That is taking the line off and hosing some water through it. If you will explain it now on this thread we will have it forever. Thanks

I echo the wish to have this info, stated as simply as possible for those of us who find even a hammer a high tech instrument.

I'll admit that this is a bit of a Rube Goldberg rig, but it is inexpensive and IT WORKS!!

Go to Home Depot and in the plumbing section get a 3/4" CPVC Street Elbow and a 3/4" to 1/2" bushing. FYI, a street elbow has both male and female connections, CPVC is the beige colored fittings (for hot water). Get 6' of braided 3/8" ID hose (1/2" OD) and a small bottle of Gorilla Glue.

The outlet for the AC discharge raw water is 7/8". The male end of the Street elbow is 7/8". With 220± grit sandpaper, sand the male end of the street elbow so that it loose enough that it just fits inside the through hull discharge outlet WITHOUT BINDING. Rough up the inside of the female end of the street elbow, male and female ends of the bushing, and ¾" of one end of the outside of the 3/8" hose. Glue the reducer bushing in the street elbow and then put a dab of glue on the hose and the inside of the bushing and press the 3/8" hose into bushing. Let the glue set up before using.

Before you launch your Ranger, insert the male end into the AC raw water discharge outlet and the other end of the hose inside the passenger window, close the window so that it will stop the hose from slipping out. Launch your boat and when ready open the window and give about four rapid suction pulls on the hose, like the way you used to siphon the gas out of someone's tank, the airlock is gone and 110V AC circulator pump is is primed with water. Before you fire up the AC, reach out of the window and wiggle the hose fore and aft a couple of times and the Street Elbow will fall out of the AC raw water discharge outlet.

This may sound complicated, but is very easy. The best part about it is, that it really works without fail....

I have not ecperienced the priming issue myself including on your boat Darrel. This seems to be happening for people that load and unload off of a trailer. If you are on a trailer then try turning the ac on with the boat backed in the water on the trailer. This will keep the nose high and help with priming. If that doesn't work then I will run the boat up to planing speed and try forcing the water in the scoop, and it usually primes by then. Let me know if that works for you!

We trail Solitude every week and have never had this problem. Trust me, if we did my wife would not be spending the night on the boat. We ran out of gas (we use a Honda generator) one night at 1:00am....... not pretty....... 100 degrees, no breeze, no air........
