Running boat out of water

Heck of a park job, he almost made it on to the trailer at the end probably wasn’t his though.

Full synthetic oil could have prevented that tragedy.

This is a little more complicated then fittings, plungers and valves but always worked for me. It also allows me to see how well the pump is working.

Tim you got me laughing here,my dad did the same with his shamrock,I imagine you do it only once! That is also the advantage of the shutoff,you don't have to take the boat out of the water to change the impeller

That makes a sense TRBenj the impeller would provide enough resistance to force the water out the intake grate until the motor was started and the RWP started to suck. I have always put a non return valve between the "T" and the intake grate. The valve is the most expensive piece to buy and I have often wondered if it put any restriction on the quantity of water the RWP could suck through it.

I always make sure the water pressure is not excessive before connecting to motor and starting the motor as soon as it is connected. The removal of the valve saves any worries with those issues.

So out comes the non return valve!!

Do you put a valve before the "T"? If not, how do you keep the water from pouring out the inlet?
I have the Flush Pro on mine. It automatically shuts off the supply side from hose pressure.

Tim the reason I wrote that was that gentleman had a leaking circulation pump and I believe he was compounding his problem by applying house pressure.I myself am a little leary of using plastic fittings and strainers with out a shut off on the thru hull tho-

robe, sounds like you've got a flush connection up there. Go with it. Eric says your tranny won't heat anyway. You'll just want to make sure the pump is picking it up and bringing it thru the engine.

OK I get that I have to connect a hose to the intake (I'll do it before the raw water filter), but will a standard garden hose fit??

Also - I see a connection at the front of the block, near the raw water pump, that has a standard hose connection and a shut off valve. It's near the bottom of the engine.

My father in-law (owner) told me to connect here, but how can water flow through the system this way (bypassing the raw water pump and engine block pump)??

If I had to guess it's because your raw water pump is not turning with the engine off and the water pressure will force itself through the impellers. Don't see how that would hurt them though.

Wakemeup,

Back to your question. I do not believe using your flush connection (I think CC knew what they were doing) or hooking a hose up to the RW intake hose hurts the boat. It's an OK way to flush or test your boat in the driveway.

What people are getting at, I believe, is that you can have a bad raw water pump and you would never know it if you use a hose, because the hose pressure forces the water through the engine. I am sensitive to this as I had that exact problem and didnt know it because I always hooked up a hose directly. So I pretty religiously use the "bucket method" now.

However, now that I know I have a new and good RWP, I would not shy away from periodically running with a hose hooked up if I had some quick testing to do in the driveway.

Not to doubt you Tow,...but where are you getting your information. Skidim sells the Flush-Pro and it can't be used by drawing water from a bucket.
