Re: Water in lower unit 1965 Johnson 9.5
Bgillen is right, it is probably just the seals. Anytime you get weeds, or fishing line, or anything tangled into the prop it can tear those rubber seals no problem. If you haven't had experience working with those, or the lower unit, I would buy a repair manual. That way you can learn more about your engine, and at the same time fix your problem. Then you would also have the manual just in case you ever have another problem because a manual normally covers the whole motor.
