probably dumb question

[stubbsboogie]

I am looking for some clarification.

When I drain my engine of water(blue valves).

If I want to take the boat out after that has been done do I have to do anything to it other than just put it in the water and start it. Or is there a priming step to it.

We live in FL and use it most all year but I wanted to drain everythnig just in case we get a cold snap. But wanted to make sure I can still go out.

Thanks guys, this is my first I/O.

Exactly, no priming needed at all.

yep- mine has valves to open & close to drain- just make sure they are closed ( I put tape over ignition key hole) before you fire it up and take off.

Yup, the water pump is in the drive, and submerged when the boat is in the water. Makes the whole thing "self priming"

Thanks guys!!!!

Now I know I am safe.

Re: probably dumb question

i got an idea..

well my engine is not cooled using radiotor. it used the sea water.

well i was thinking about draining the engine and the exhaust manifold using air pressure.

i wanted to know if its a good idea to add a valve where i could connect air line into the water housing so it will blow all the water out of the engine and the exhaust manifold

For a volvo with the impellor at the front of the engine is there an issue with priming?

How cold does San Diego get?

Never had any issues with the pumps on our volvos. I like to squirt some dawn back in there to lube the impeller till it gets water though.

Not a dumb question...But an opportunity for clarification.

My thoughts on the air pressure thing....

I would think it might work, however at the end of the elbows (where the exhaust and water mix) the air (and water you are blowing with it) would be able to back pressure into the exhaust side of the manifold and may rust in the head or cylinder if the ex valve is open..

Why the need to go to extremes to get every drop of water out of the engine (via air compressor and fittings), when pulling the plugs and draining the water works? ... and it works in areas that go down below zero degrees... and it is a proven method. Why the need to go crazy in San Diego? Even if you went to Canada, you don't need compressed air.

longstand, I actually enjoy reading your posts -- I really do. But one thing that concerns me is that you seem to create more work for yourself. You know boating takes a tremendous amount of effort. It's like owning your own race team. To get the car on the track for a few hours, hundreds of hours, thousands of dollars and many restless nights are in order just doing what is required. No need to make extra work for ourselves!

Enjoy, longstand. I look forward to reading your other posts. Happy boating. Keep it simple and it is more likely to work and be enjoyable!
