I have a 5.7 Mercruiser Bravo Two and i have Gear Drive Oil coming out of the little container, i refill it and run the boat for a little while and it leaks thru the little hole on the container cap!!! it comes out because of pressure coming from the transmission i dont know why i have that pressure to spill the oil into the engine compartment!! im worried my transmission will die!! i already check for hose line might be obstructed but all looks fine!! ANY IDEAS??
