I've done searches, and I know there is already a ton of info here, but I couldn't find it. In my 18 years of owning Sea Ray Cruisers, I have never had any work done to any head system.
My Master head motor now runs and, apparently, does not build up vacuum. I had the dealer mess with the pressure switch, but I'm pretty sure that was a waste of money (no pun). It appeared that the problem was that the pressure switch was not sensing the vacuum and shutting off the motor, but now, I'm pretty sure it isn't building vacuum.
The motor seems quiet, as if it's not working too hard. The draw on the DC panel is not as great as when the other head motor is pumping. All indications are that the problem is the bellows then, right? If so, what do I replace while I do the bellows? The duck bill valves I assume? Do I automatically go for the motor? It seems fine.
What source do you all use for the parts?
Thank you.
