Boy, do I have the trouble, just put a rebuilt lower unit on my 1989 50 hp Force motor last summer, new everything put in according to the boat shop repair tec. and today as I took off down the lake the buzzer went off on the boat motor,from the time I took off it was something like 3 minutes, so I switched it off and let it cool off before heading back to the truck, got almost back to the truck and the buzzer went off again, it,s peeing some water out but I really don,t know how much it,s suppose to put out, I know a little about boat motors so I removed the lower unit when I got home and it has quite a bit of grease or oil in the housing part where the water pump is located. but that is all I can do about it because I really don,t know what I,m looking for. Sure could use some help on this problem if somebody can give me some good advice on how to fix it or what to look for. Thanks for any help.
