Cover Nut tool?

[Rudderman]

I'm disassembling/rebuilding a 1979 20hp Merc. I'm using the Seloc manual. I've managed to get the lower unit off (LOTS of hammering and wooden wedges).<br />I'm at the stage of removing the Cover nut behind the prop and I think I need a "Cover Nut Tool". Where would I find one, or is there an alternative to buying one?<br />I saw this one on ebay but I'm not sure if it would fit my engine....any thoughts?<br /> http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=4526337133&category=26455

Re: Cover Nut tool?

hello<br /> you will find that tool is useless for the nut removal if that motor has seen saltwater. I usually drill 3 holes in the nut and crack them out. the tool or a homemade one will be required to install a new nut. the nut is made of cast aluminium and will break apart rather easy. take care not to drill damage the case threads.
