SUJET :

So first of all sorry this is in English, but if I tried writing it in French you would simply not understand.

I am looking for the best stainless steel propellor to fit to my Medline II with suzuki 140 4T to get the maximum speed. Currently I can easily get to about 34knts (two people & 100litres of fuel) but the engine is running about 5800 rather than 6200

Has any body had a similar experience and what did you choose, what was the gain?

Merci

Nick

Welcom on board

(but I don't know any thing about propellors, sorry)

Obtenir plus de vitesse de mon Medline 2.

Avant tout je suis désolé c'est de l'anglais, mais si j'essayais d'écrire en Français vous ne pourriez tout simplement rien comprendre.

Je recherche la meilleure hélice inox pour mon Medline 2 avec Suzuki 140cv 4temps pour obtenir la vitesse maxi. Actuellement je peux facilement atteindre environ 34 noeuds (2 personnes et 100 litres de coco) mais le moteur tourne à environ 5800 tours au lieu de 6200.

Quelqu'un a-t'il une config' similaire, qu'avez-vous choisi, quel résultat ?

Thank you

Nick

Tant pis j'essaye::e-
What are the actual diameter and pitch?
Suzuki recomend 13 5/8 X 15 or 13 1/2 X 17 or 13 3/8 X 19 or 13 1/8 X 21 for stainless still propelors.
You have probably more long pitch.

C'est compréhensible???

C'est comprehensible, on entend presque l'accent corse

Just in case you didn't know it Nick, you can find the diameter and pitch of your propeller engraved on the propeller itself.
Since a 19incher on a similar setup yields 36 knots at 6200 rpm, yours probably has a 21' pitch if the diameter is the same.

suzuki delivers the engine (df 140) with a propeller of diameter 14.
