1993 225 90deg<br /><br />I'm doing my homework prior to water pump rebuild - seems straightforward except for one thing - the tube thst carries the water to the engine from the pump - the parts diagram shows no grommets/gaskets/o-rings. Does this part come out with the lower unit or stay with the engine? Is it just a press fit? No grommet or other sealing psrts? Seems strange. The Clymer manual hardly mentions it except to say it comes out and simply goes back!
