2003 BF225 Sabre LU getting water inside.

[Lowtree41]

I make 3 trips to my local lake then drain and replace gear lube because it always shows some water. I can put 10psi of pressure on it and it will hold for an hour or more. Cannot figure out how the water gets in? Is it possible after a run the hot gears create a vacuum and pull water past seals ?
Any ideas appreciated.

Replace the prop seals. My guess is the outer prop seal is cut allowing water to get in. May want to replace the seals on your plugs also.
