Re: leaking prop
First verify you are getting water in your lower unit by removing the drain plug and cheking oil. If it is white or water comes out you have a leak. If this is the case you are problably leaking oil from the bearing cage and it will have to be removed and a new seal purchased. If the oil was black it might just be carbon from the exhaust leaking down on your prop. This is probably not the case because this is a four stroke and black oil would be two stroke oil mixed with carbon.
