trying to get my plastic pirhana prop off my out board but cant get the fooker off, thinks its siezed on, any ideas

Spray with WD40 and leave overnight.

done that for 2 months most nights of week, didnt work, and i drenched it in it

You need to use a gear/hub puller on it.

i would have done but cant find one big enough, any ideas

Four equal sized wedges, two pieces of three by two, and a G-clamp?

got the 4 wedges, whasts 2 pieces 3x2 for?

Two wedges each side of shaft, thin ends inwards, between housing and base of prop, three by two against thick end on each side to enable g-clamp to exert even pressure on wedges. Leave nut loosely on shaft and lightly tap as you take up pressure on wedges.

big thanks to kimpri1 for getting the prop off for me, fu cking top bloke!

got a new stainless steel prop, fully greased splines, time for some under water object churning in the mersey me thinks

"probs" to kimpri I say
