Uim Powerboat

I look Powereboat UIM P1 series on speed, and I wondered where the water intakes are on the boats. Often, the only thing touching the water in the screw, but watching the water coming out of the exhaust, it is not constant.

The intakes are generally lower in units. There are times when it is blocked and a pickup through the shell is used.

Search design.
Clearly they are at the rear of the hull ... for the district of the shafts. The exhaust gases from the water are not constant clearly indicated that the doses are not always in the water.
Pretty simple stuff.

Perhaps there isn't any see if there is a rad???

They are in the lower units, and racing of readers, they may be at the lower end before the ball and on the sides.

Boatman is right. The lower unit contains a water pump that is driven from the vertical shaft. Water enters through the entries in the drive and push himself to the engine.
