hamilton gate to nozzle conversion

[mad mike]

seen this unit on trade me http://www.trademe.co.nz/motors/boats-marine/parts-accessories/engine-parts/auction-438044754.htm will it fit something similar to this without major mods http://www.trademe.co.nz/motors/boats-marine/parts-accessories/engine-parts/auction-437482070.htm or is it a bolt on part not sure on model of unit either

Its a 750 series, the correct noz for them sleaves into the tail pipe and picks up the 4 bolt holes the flaps used too use. they suck because you cant use wedges too change the trim    . Colorados and 770s flat mount on the surface like the one in the TM add (Hartz Marine ).
Heres what ben did http://www.nzjetboating.com/yabbse/index.php?topic=19379.330.
You should have no trouble picking up the right nozzel for it though, I know where 2 second hand ones are because everyones getting trim nozzels now.
