Ship propellers stolen for scrap
A GANG who stole £220,000 of ship propellers and tried to sell them for scrap were jailed for a total of 13 years.www.liverpoolecho.co.uk
"None of the property was ever recovered."
I did like this though:
The Captain of a Russian Destroyer Allegedly Stole His Own Propellers
That's some seriously expensive scrap.
Not from what I understand, well with regards outboards anyway. You really only get two materials for outboard props, aluminium and stainless. The stainless tend to be used for high performance but there is a big drawback to them, they are a lot stronger and if you hit something then you are more likely to cause gearbox damage. Aluminium, not being so strong will be the weakest link so it is what most go for.
800mm might be a bit big for an outboard Robin haha
Yes but I was replying with regards salt v fresh water and the material
Yes but, yes but..what vessel with a prop that size operates in FW?
Rivers. Inland seas. Lochs
Without a pic of the thing itself we cant know, over square props are common in high speed high power applications & can be surface piercing, Stainless is often used for these. Steam boat props are intended for low speed but extremely high torque, so if your engine is limited to 3 - 400rpm the only way is to go as big a diameter as you can swing with correspondingly heavy pitch, My late father in laws steamboat for instance had an 11 indicated Hp compound engine, but it could swing a 22" X 28" , when you linked it up into forward drive the big chunk of bronze whirled round & she just moved.
