Hi I am an writer writing about a trip to The Barrier Reef from Gladstone Queensland in 1929-1930. I have them aboard a sailing boat with an auxiliary engine.
What type of engine would they have then? A friend suggested a Chapman Pup. I wondered about an old car engine. Any suggestions would be appreciated. |

Car engine conversions usually didn't stand up to the rigours of marine use.In a car, the load on the engine is much less than in a boat.
In a boat, it is as if the engine is driving a car up a steep hill all the time, there is no level ground or downhill.
An auxiliary engine like a Chapman Pup in a sailboat would give it the maneuvering speed it might need while going into or out of a mooring.
An engine in the 10 - 15 HP with 2 cylinders would probably be used in that era.

Thanks for help. Still not sure. What 10-15 HP Marine engines would have been available in the early 1930s
It seems the Chapman Pup would be unsuitable in a 37 foot Ketch rigged launch that is supplying a turtle soup canning factory on a Barrier Reef Island |

Graham, In that ere the engine may well have been more like a 10 HP Chapman Sea Dog or an Acme 10/12 HP twin (Manufactured in Newcastle NSW) They were the bigger engines of the time. Although it may even have been fitted with a Kelvin diesel which were also popular for larger boats of that era.
Just a few suggestions but definatly not a PUP... Too small.
Cheers, Dave. |
