I have around 20 hrs on mine now. No listing to port. I haven't checked the battery voltage yet, but when I first got the boat, Connext was showing different readings for each of the two batteries. Now, it always shows the same voltage. I'll get the multi-meter out and check just to validate
@subysti 's detective work. I can't help but wonder if flipping the parallel switch on and off at some point (not that I needed to, just seeing how things work) caused the problem to show itself. I wonder if disconnecting the parallel switch from the batteries would correct the readout problem. Ya gotta wonder if the parallel switch is the defective part.
I've noticed inconsistencies with respect to the amount of water that drains from the boat. While in Bimini, I chatted with
@upperdeck about this. He observed that it takes a steep driveway and a propped up trailer tongue to get all of the water to find its way to the bilge drain. I get the sense that water gets held up in pockets between the inner and outer hull shells. When we were in Bimini, we got a good amount of rain one night. The next morning when I turned on my batteries, the Yamaha bilge pump ran for almost a minute. I have a secondary bilge pump that connects directly to the battery and it is set to engage if the water level rises above the Yamaha pump's level. The secondary bilge pump did not run while I was on the boat, but it could have run through the night. So, for all intensive purposes, my boat should have been pumped out. Being a new boat, I was curious to see if there was any water left, so I opened the engine cover and there was no water. I unscrewed the two plugs in the engine compartment (one points downward and the other points to the fuel compartment). No water flowed. I opened the plug in the bottom of the ski locker and water flowed into the ski locker... wrong direction. I'm guessing that the drain channels between the inner and outer hull are plugged and/or are angled to the point that it's a really slow drain from some parts of the boat. I'm also guessing that driving around gives the water that is stuck in these spots a chance to slosh it's way out to a spot where it can find its way to the bilge. The other day, after pulling the boat out (i.e. up the inclined ramp), still with the stern/keel drain plug in, and pulling the boat 200 yards to the storage unit, the bilge pump was inactive until I raised the tongue about 4 inches when unhooking the trailer at which point the bilge pump turned on and shot out half a gallon. After that, I pulled the main drain plug... not a drop. I'm tempted to buy a scope to stick into these cavities and see what's going on.
At the 10 hour mark, I filled my engine compartment with water, above the Yamaha bilge pump activation level and I looked for water leaking out of the bottom. There was none. So in my case, it doesn't seem like water is coming in from the bottom of the boat and it definitely seems like water is not easily finding its way to the bilge or to the stern/keel drain. When I filled the boat with water, I used this as an opportunity to completely remove the plug and it's retainer clip in order to stick a screw driver into the drain hole and stir things up while the 10 or 15 gallons drained out. Lots of aluminum drill filings and lots of spray foam bits. The spray foam would definitely act as a drain channel blocker if it was misapplied at the factory. I'm probably carrying a bunch of water in various pockets in the boat all of the time. I wonder if this could be the cause behind the boats that are listing to the port side. If expanding foam was misapplied at the factory such that it creates a non-draining reservoir on the port side of the boat, then you've got a list.
