Penta Sail Drive - Diaphragm Life Expectancy
« on: May 23, 2019, 06:46:01 PM »
Does anyone have any information/recommendation on determining the life expectancy of the sail drive diaphragm?  Some literature I have read says it should be changed every seven years.  Is the seven concecutive years or seven years of service (ie:  in the water for three months a year, so 28 years).  Is there anyway to test the diaphragm or are there signs to look for that the diaphragm is failing (obviously a leak is one)?

Any information on this topic would be wonderful.

Cheers again,
