    Prop removal and installation / thrust washers, tab washers, etc.

    So I bought a new (to me) Hydrostream Valero with a 1995 2.5L Mercury offshore engine. The second time out I get the prop in the lake bottom and bend up the ears I have sent the prop off for repair but have questions about getting the thrust washer off.

    The one on the prop shaft is 3/4" thick and doesnít have the step design I have seen on the boards. It is approximately the same diameter. What is the best way to get it off? I am a bit leery of taking a ballpene hammer to it.

    When replacing it what thrust washer should be used (part number). The prop a Mazco re3 28p that came off only had a nut and a tab washer. It also had what looks to be a thrust washer with grooves for the tab washer built into it.

    I have another prop I would like to put on the boat so I can get some more use out of it before the end of the season. This prop doesnít have a flush front, it has what looks to be a washer in the insert that sticks out about an 1/8". The back is recessed some with room for a washer tab washer and nut. Itís a stainless steel prop with a similar hub design as the Mazco.

    Suggestions on the removal of the existing thrust washer and parts to install the other prop (and the Mazco when I get it back) would be appreciated.

    If need be I could scan the prop in questions.

    Thanks,
    Steve

    You should just have to give it a tap with the hammer and it should be loose.

    Tap the thrust washer face closer to the outer edge. Use a brass or aluminum hammer.

    I use the Merc stepped thrust washer with all my props. Merc, Mazco and Power-Tech.

    YUP!

    The propshaft is tapered where the thrust washer comes into contact with it so all you have to do is tap it and it will come loose.
