Here's one for the mechanics out there, and anyone who knows Moomba hopefully.
Brother in Law is running a Moomba boat that's listing pretty badly to the starboard side, the ballast bags are empty. It has a central hydraulic attitude plate but does not have trim tabs on the sides. No noted hull fouling or puddling water.
It does seem to be taking on a good amount of water and the bilge will regularly pump out when you drop onto idle.
But I cannot find a culprit - how likely are these boats to soak water in the floatation foam?
