Drive shower pickup tube length
 

Does the length of the drive shower pickup tube affect prop performance? If so, how much tube should extend below cavitation plate?

Yes it can.

Just enough tp expose the angle of intake.

Thanks, how does the length effect prop performance?

It can effect water flow to the propeller.

Depending on the placement, angle and length, the tube can cause a ventilating issue to the face of the propeller blades.

This scenario is relatively rare.

Also, as related to performance in general, anything in the water flow creates drag.

That's why I use this type of "pick up"! :D

where are you picking up water. and I also agree that the tube length has a effect on the water to the prop. I shortened the pick up and fixed the blow out.

Sea water pump.

were are you getting the water from?

Julie/Brett, pick up tube downstream of the prop can effect water flow to the prop? My IMCO drive shower tip extends 1 1/4" below cavation plate and is less than 1/4" from prop tip. This is too close?
