DIRECTION =RH (as you can see - propshaft must turn, clockwise from aft view, to go fwd)

DIAMETER = 13"

PITCH = 8"

BLADES = 2, turbine, aft raked

CONDITION = Old/Worn Used, very pitted, which I cleaned inspected, decided to cover in antifouled blue paint, so it appears better in photos.

how long the paint will stay on maybe short, but you can keep repainting it, and/or add a sacrificial anode (shaft ones are £15 and easy to fit) to protect it in future

price reduced accordingly. a new one would be 2 or 3 times as much

SUIT = Vire 7, possibly Vire 12, , vire 6, also other RH prop engines

SHAFT DIAMETER 25mm

SHAFT/ HUB TAPER = 1:13 (as you can see - propshaft must turn, clockwise from aft view, to go fwd)(there are three other common tapers)

HUB MEASUREMENTS FOR SHAFT= (dia at aft end) -(mm in=mbetween) - (diameter at forwards end) = 21-55-25

MATERIAL =Solid Bronze(best grade), , suit a lighter (<2 tonnes) racing or sail boat with a low displacement hull.

blades raked back, so bigger installation space, but higher mpg efficiency and speed, particularly motor sailing."

single woodruff slotted 5mm wide by 2mm deep

will fit 1" shaft(25mm) , or could be adapted for smaller shafts

ideal for Vire 7& 12hp instalation

now cleaned inspected and polished - POOR condition this prop is in , many shallow but large pitting , MANY fissures and little dents (approx 200 of 0.125 mm deep x 5mm long by 10 mm wide) . I have painted with anti-corrosion red oxide to smoooth it out and blue JOTUN antifouling to halt the corrosion and cavitation that might ensue, it looks ok, but underneath the paint, its a bit rotten so would need repainting every year or more depending on use/saltiness of your mooring - big discount,. price adjusted accordingly..

I think this is a prop from VIRE. IMHO 13 x8 is fine for the 7 & 12 VIRE, unless its a vire 6,this prop would not shift enough power for an engine above 25hp Generally:

so it's optimal for about 5-8knots @ 1000-3200rpm (2:1 reduced petrol engine / direct diesel)

(if your crank turns clockwise from the front, chances are that gearbox reduction reverses direction and you need a RH prop like this)

the low pitch of this prop and the 2-blade design would optomise it for a racing cruiser because it could be locked vertical, give less drag, and higher speed on a more streamlined boat without labouring the engine.

some vire shafts are less than 1 inch (22) so this prop would need re-bushing to fit them(but worth it for such a nice prop)

there is a good keyway for the shaft's woodruff key, your nut would have to be secured with something like a split pin or a tab washer easier.

I have a shaft to match -1 inch shafts are easily available.

modern equivalent props normally cost approx £250-350 specially cast.

a 2-blade prop can be parked vertically, which drastically reduces hull drag, if you are sailing with a locked prop.

I had an identical style prop on my own boat and it never needed cleaning in its river mooring.
