Remove water intake pipe on 25hp Yamaha outboard
There is an intake pipe on the water pump in the lower unit. Is this the one you are refering to? The water enters the lower unit through side screens and takes it directly into the pump. The pump impeller is driven directly by the driveshaft and is an easy replacement. I have the manual if you need the pages scanned.
35hp Yamaha motor oil alarm goes off after about 1 hrs running
under the engine cover there is a reservior that holds oil that is pumped up from the large tank. The reservoir has a plug on the top which is a float switch that switches the pump motor on to fill it. either the float for the alarm isnt working or the same float to tell the pump to turn on isnt working. check the connection of the wires coming off that plug.
