A buddy of mine has a Bravo 3 that is building up high pressure in the gear lube reservoir. It is so bad that at one point it ruptured the barb on the reservoir and spew lube in the bilge. He replaced the reservoir with a new one, but still has the pressure problem.
The reservoir was properly filled when it was replaced. He ran the boat this past weekend. Then yesterday he noticed that the reservoir was full - not to the full mark, but to the top of the bottle. He slowly unscrewed the cap and you could hear the pressure releasing. The boat had not been run in several days.
I realize that one source of this type of problem would be a hot outdrive. But I assume that after it cools down the pressure would go down as well. Kind of like a car radiator - maybe a poor analogy. And I'm not sure why his outdrive would be experiencing abnormally high operating temps.
Any ideas?
