Yamaha Year Models This Yamaha outboard year model chart will only work for Asia Pacific distributed engines. If you have a Yamaha engine that has been bought in from America or Europe direct the parts will still be the same but your model and year model code will be different. You will have to use your own knowledge of your engine to select the appropriate year. For Asia Pacific engines your year model code is found on the bottom right hand corner of your serial number decal. It will be a single letter as per the diagram below which can then be matched to the chart. Note: The letters will repeat in the below chart so use your judgement as to the correct year, ie: the engine in the picture is a 2003 model and not a 1982 model. 1973 1974 1975 1976 1977 1978 1979 1980 1981 1982 Z Y X W V U T S R 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 P L K J H G F D C 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 A Z Y X W V U T S R 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 Q P N K J H G F D C 2013 2014 B A

would need a lot more information before i can help diagnose

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.

salt water boat? sounds like you have salt buildup under the head where the thermostats are. gotta take the heads off and clean the salt deposits that are reducing waterflow

gotta check cylinder compression to see how tired the engine is. having said that, im still very confident of my 1987 175 yamahaand thats in salt water

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.

Sounds like a head gasket, worn valve gasket, as my first guess.

There should be a vent on your gas tank cap . Open it up so the tank can breath. If no air gets in it creates a vacuum causing the primer to collapse and will shut down the engine. If there is no vent turn the cap open a little just to let some air in but those tanks should be able to vent.
