Prop Size

Can someone tell me what size prop I need to put on my 1974 Morgan 27 or 28. It is an OutIsland It has a 18 hp westerby in it and the prop is missing. Any advice will be appreciated.

Thanks, Wyatt

IT would really help if you said what the transmission gear ratio is as well... with out that piece of information, can't make any recommendations.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

If you look at the engine/transmission, it will likely have a label that has important information like the model of the engine, which is likely a Westerbeke, rather than a Westerby... which isn't a make of diesel engine AFAIK. It will also have things like the HP rating of the engine and the engine serial number as well as the transmission gear ratio.

You can see the label on this photo of a Westerbeke engine, just right of the bronze water strainer, silver and black on the top of the engine:
