Assume you are talking about a shaft drive diesel installation. Seems like the Triton 24 standard configuration was an outboard in a well, with diesels done as special orders. As such suggest you get a suitably experienced company to assist in the correct propeller selection to fit the existing shaft - need more detail - the axial length of that 19-25 taper as well as keyway sizing and end thread / castellated securing nut. What happened to the original propeller? Are you looking for a new folding or feathering prop or just a conventional 3 bladed fixed pitch type? You also need the diesel rev range and gearbox ratio to sort pitch and blade area given a diameter limit, and the "hand" of the prop to make sure the geometry is correct for thrusting forward when in fwd gear. Assume you have checked good articles on all that is involved - eg here
www.pbo.co.uk/gear/choose-right-boat-propeller-62058 Over your way ThePropellerSpecialists look like they would be able to assist
thepropellerspecialist.com.au/ On the east coast DH Porter and others would sort it.
Jolene (forum member over your way) would be able to advise any other suitable companies.
