Bilge hose - important difference!

Using a 6' long piece of straight wall 3/4" garden hose, after 15 minutes the measured output was approximately 180 gallons, or about 620 gallons per hour.

Minor math correction 180 x 4 = 720 GPH. Just wanted you to know i was paying attention.

Interesting results, but the real question is "how long did your battery last before the young ladies sunning in bikini's got wet??"

The issue I've had is the wire reinforced hose will not hold when clamped and will come off, at 1 1/8" seacock fills the boat quick.

For the test. I used the 1 1/8" hose that has threads running through them, but not wire. After the test I used that piece to replace the corrugated hose on one of my pumps

Wow. Thanks! That is truly valuable research, not sure what hoses I have on the Seafari (still rewiring) but that will be definitely addressed. I would have never guessed the the difference to be so significant. Fantastic info. Send that to Mythbusters...

ps. what kind of mileage did you end up with on the 90 Optimax?

Unable to get my navman working. My estimate is about 5.3 to 5.5 gph at 23-24 mph, or about 4.5 mpg. I ran for one full hour (timed) on a 6 gal. portable tank, and still had about 1/2 to 2/3 of a gallon left.

What I cannot believe is that they actually advertise that black corrugated hose at "bilge hose"... Not only does it restrict flow but when I tried using it I had to replace it once a year because it would get brittle and crack/break in the heat.

From experience - bilge pumping water out under top cap onto deck is not good...

I do believe, we have our own "Myth Buster" here on CSC. How cool is that.
