Leak at transom assembly
Before launch of my 350 I had both B3 drives pulled and pressure tested. Marina reported that the bellows were in great shape and no need to replace.
After launch, I noticed a not insignificant leak on the starboard side. The water was running down from somewhere mid-transom assembly and dripping off the lines in the area circled. It was hard to tell how much water since the coolant hose to the water heater blew when the boat was first run so there was lots of water in the bilge. I didn’t get a chance to investigate further as we went into yet another lockdown here and no marina access allowed.
I asked the marina to investigate. I suspected maybe the shift boot was not installed correctly (as I am a certified armchair boat mechanic). They said no way that’s possible but that they will haul and inspect.
Marina pulled the boat yesterday and they believe there’s a leak in the bellows (tho they cannot find it) and they want to replace the bellows to validate.
I’m fine with this but I have read that a leak in the bellows would not cause water to leak into the bilge; rather it would just fill the exhaust. Does this make sense? I generally trust the marina but...
