That would b an interesting number. Could put a lot of speculation to rest.

http://aqualarm.net/datasheets/one_a...w_detector.pdf
seems like the one I listed has a better flow rate up to 28 GPM...I wonder if these things are really worth it.

I would love to install as one more safety measure....I am a proud card carrying OCDMC'r.

170 days to research and decide.....

Does not seem to be popular here on TT, but I installed the Perko Flush Pro, now 4th season and it works great. Ran the engine for 20 minutes for her oil change at 1500 RPM's and the water temp using the house water supply, never went much above 160 degrees! Pulled the Impeller with 60 hours on it and it looks brand new.

I understand the bucket problem and the system pulling more water than the hose can provide, however this proves that it is getting enough water to keep the engine at proper operating temp. I also don't like the Fake-A-Lake attached to the scupper, these leak pretty bad.

Lovin the Perko - Cheers...

Do you put anti freeze in your boat? If so, how do you get it in there with the Perko?

+1 here. Been using the Flush Pro to flush and winterize my 205 for 14 years and have never had a problem as a result. My assumption is that if the hose can't keep up, it's not running "dry" - it's still running with as much water as the hose will supply. It seems to be enough to keep the impeller lubricated and to provide sufficient cooling at lower rpm's.

Same water connection, there is a little black plug that presses in on the spring to allow the antifreeze to flow. I have a 5 gallon winterizing jug I purchased for my I/O, works great, has a water shut off valve and clear hose. Here is one from overtons, this is a little nicer than the one I have, mine is all plastic fittings. I use this to put antifreeze into the ballast tanks too.

FYI - I purchase -200 green mixed 1 to 1 with warm water. 6 gallons total. -68 burst and -28 freeze protection mixed. 3 gallons for ballast, 2 gallons mixed in each tank. 2.5 gallons for engine, 5 gallon mix and 1/2 gallon for heater.

As a test of your level of OCD, did you performance test the new stat in a pot of water prior to installation?

Somehow I skipped that step when I replaced the stat on my boat and the darn thing hardly opened at all!

Wow Peter, I've never done that. Do you need one of those high temp candy thermometers for that test?
