Merc 15 2st Impeller Fitting
Hi guys, got a used Merc 15hp 2 stroke here and need to replace the impeller.
It would not pump any water out the tell tail ( only for 2 seconds at start up and then stop ) the inlet / outlet and hoses have been back flushed with a hose.
I then removed the impeller housing as shown
I'm unsure as to wether any gaskets or washers are missing so have taken photos of the removal, so that you guys can see and advise if any parts are missing etc.
There were no washers on the shaft or impeller.
I'm also unsure of how the water intake pipe connects to the impeller housing, does it simply sit on top of the housing or should it be inside before the casing is bolted down.. or .. ?
When the gearbox was removed, the rubber part was left attached to the main intake pipe up inside the leg
The base plate has some ring marks on it from the impeller ( see photos ), is this still ok to use or should it be replaced ?
1 last thing, how is best to remove this hard glaze stuff like varnish off the parts?
