WANTED: 26"D 20P LHR 3 Blade for 1.5 inch Shaft

[Latitude9.5]

Looking for something to have as a spare prop. shoot me a message if you have something in decent condition.

thanks!

I'm curious as I seem to have a 20"D X 20"P prop and I am grossly over pitched. I can only get 1600 rpm (40 hp) at 7kts!

I would be about 15tonne, 44'LOA and 75hp at 2500 rpm, which is similar to you.

You are going to use a 26"D X 20"P for 85hp?

I am planning to get the prop repitched down to 14-16".

i replaced a 26/20 feathering prop, with my spare fixed prop 26/20 so i just want a backup, always nice to have a spare. I'm 45.5 LOA at 18 tons with an 85hp.

What engine speed (rpm) do you get at full throttle?

[Talbot]

Sounds to me like there is a different gearbox ratio between these two boats

[Latitude9.5]

Engine is rated for 2600 i cruise around 1600 to 1800

I really wanted to check the accuracy of my calculations for repitching my propeller with some real world data.

If your gearbox is in the range of 2.5:1 to 3:1 then my calculations are on track.
