1993 Yamaha 175 2 stroke Steering Bearings and Running Hot At WOT

[Reece1804]

Hi, I have a 175 2 stroke yamaha on my 1993 Southwind SF20.
I am having difficulty pumping grease into the top steering bearing/bush on the engine resulting in tight steering. It appears that the upper and lower bearings share the same grease nipple and the grease seems to just pump out the lower bearing (path of least resistance). Does anyone know a way of getting grease to the top bearing???
Also I have an issue with the high temp alarm activating when I operate the engine at WOT for about 1 minute. The water pump impeller has been changed and the mechanic said the impeller housing had some scores in it, could this be the cause of my overheating problems?
Thanks

Rod are you self medicated this evening?
I am getting close to having to shut it down myself

OP Water pump kit has cup and wear plate in it,
that is what the impeller rides in

If the housing has a problem then it needs to be replaced also

there are a lot of other things that can cause over heating
