Re: Overheating cylinder, mercruiser 7.4L

Re: Are all membranes basiclly the same?

Chinese membranes don't work as well and don't last as long.

About 3 gallons more are pumped for each gallon of usable water. Only about 1/4 of the water is drinkable. The rest flushes away the salt. If the hand pump produces 900 psi you could use a regular...
