Hi,please help me with following:on port of my first I have a problem with water bursting in inside of my boat. in bigger sea I can get in 1 hour app. 300 l of sea water inside.Is it possible that my outboard support can take so much water in if possibly poorly waterproofed or is it possible that after 7 years joint between upper and lower haul can be porous and is taking water there. I am taking water also when sea in not rough. when ever I am sailing.please advise what kind of sealant should I use or what should I do? My belief in good specialist has become very bad since these problems came after some specialist installed my engine carrier (so I was told since I own this boat only a year)thanks for all your post.
