Hello everybody.

I want to build joe or atomite VO152 boat.
But i would have liked to build engine transmission .
Do you have already this operation and if yes with what support.
Thank you in advance.

Hi Jean-Luc

Yes - people tried to build a gear transmission and
No - It makes not realy sense.

The gears rotate with up to 26.000 turns per minute. You need steel gears with Module 0.5 - that's too smal for a long life and all the work you will have. The easiest way is the flex shaft.

Best regards, Kay

Thank you Kay for your quickly answer.

I see in this forum a man who had built system with flexshaft.
i'm going to get inspired of this .

Salut Jean-Luc,

en effet plusieurs des membres du forum ont réalisé leur Hors-bord eux-même et parfois de manière très simple.

In tube de laiton diam 6mm extérieur cintré et de la carte circuit imprimé double face de cuivre pour former le corps.

Pour le passage de l'axe de l'hélice (axe diam 4mm) si tu n'as pas de tour à métaux, tu peux, dans le tube de 6mm passer un bout de tube de 5mm qui aura un diam intérieur de 4mm.

voilà pour la théorie....

Bonne construction
Gema

Why not.

I test that and see.

Thank you for your answer.
