Each model has a unique blade design and has a unique performance signature. When discussing prop, always include the model with the size. A good prop will reach WOT rpm when the boat is running light, no crew or gear. The Enertia, Vengence and Rev 4 (4 bladed) models are good all-around performer. The diameter of the prop is established by the outboard gearcase. The pitch is determined by WOT rpm's and target boat speed and a few other factors. What is the year of the Verado? - need the gear ratio- I see there is one authorized Mercury dealer in Israel. You may want to contact them and see if they allow testing/exchanging props. Here is the Mercury dealer (from factory website). https://www.ambil-yam.co.il Edited by Phil T on 01/03/23 - 9:53 AM 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT

How much gear/supplies? lb or kg? Do you go in large waves or only calm? What do your local dealers have available? Do they allow returns? You may need to test 2-3 sizes. I would go with either Enertia or Vengence. Enertia cost more. The Enertia requires a slightly larger pitch than the Vengence. (17" in Vengence = 18" in Enertia) As for the pitch, I would start with a 17 in the Vengence and an 18 in the Enertia. You want to run the engine 2 holes up, top bolt in the 3rd hole down from the top. Please report back rpm and speed at full throttle. Detail what the load was in the boat (people, fuel, gear).
