Welcome aboard.
What's a "helix"? Impeller?
it will be used in a 4.0 meter long zodiac inflatable boatThat is the 9.9 15 HP model engine but the with the older style mid section of the 18 / 20 / 25 hp models.----Marketed as a " commercial model for a few years to get rid of older parts stock.-----The propeller you need is determined by the boat that you are going to put this motor on.----What boat are fitting this motor on ?

ok but I could recommend the best propeller or propeller to mount the Jhonson engine in a 4-meter zodiac inflatable boatIt is MARKETED as a 14 HP-----But it is the 9.9 / 15 HP powerhead !!!-----Uses an adapter to use " old stock " 18 / 20 / 25 HP mid sections out of a warehouse to clear old inventory.----Pretty simple stuff to me.
Is that a non through hub old style prop ? If those props are not available, you're fried. How loaded, number of passengers do you plan going boating with ?
Happy Boating
which of these two propellers would be correct??----Correct ----The older 18 / 20 / 25 HP midsection / lower unit did NOT have through hub exhaust.----And why would you think those props are not available ?
The truth is, my friend, that there is no boat shop in my city and I just bought this engine and its engine is damaged, so I would like to change it for a new one and also damaged good engine maintenance. I write from Talca, Chile. greetings and thank you very much for your helpNeither one is correct.-------Do you not have a boat shop that can assist you in selecting a prop to fit the 18 / 20 / 25 Hp lower unit on that motor ???----This is really puzzling on how you are trying to find a prop !!!
