Hi guys i am studying the lower unit and i realy dont know wich bearing hold the shaft from axialforces of the proppeler.
I know how the gear work with forward an revers gear. There are lot of bearings but they are just for holding the gears.
Does someone of you guys know wich bearing holds the axial force of the propeller shaft??
Thanks a lot:)

Items 3 and 4 take the forward thrust of the propeller.

Helo thanks a lot for your answare. First i thougt this also but the gear ist supported in and outside. I think item 3 and 4 just support the gear. There is a needle bearing inside the gear and this can't take axial forces. So the propellershaft is not fixed??

Tobias, I think what you may be misunderstanding is that the propeller shaft has shoulder machined at the forward end of the clutch splines. This acts as a thrust surface at the forward gear which is then transmitted into the forward gear and the tapered roller bearing.
