Best water pick-up ever!

Hi guys Ive just fitted these..

I was wandering the pro's and cons of using them, Ive been told to expect them to cause a 10kmh drop in speed form the drag they will cause, which Im not to worried about. Just want to be sure Im not going in circles creating more heat with the drag, than Im gaining in cooling ability with this type of pickup.

I would definitely file them down some, you don't need that much in the water to get good flow. Seems like a bad spot for them too. Have you ran the boat like that yet?

[TristanJones]

No not yet, will try this weekend. Why do you say bad spot?? Have you used this position on the genesis hull and had issues??

[Heaving Earth]

That's gonna create ALOT of drag

Correct!

I'm not sure if even alot of top car guys realize what the thermostat actually does, the system is really based on the radiator and not the thermostat. The thermostat and cap are in relation to the amount of heat dissipation the radiator can preform at a given airflow. Bigger radiator more cooling. No forward movement of auto= no cooling. This is why they install fans, to help with cooling. The thermostat is designed to restrict water flow at certain temps (allowing radiator to dissipate more heat through air thermodynamicly). So it's not really addressed in simple physics because the components in use are limited. X amount of coolant in closed system dependant on x amount of cfm (airflow) all in a relative ambient temperature. Anybody know why ski boats don't have radiators? The lake they run in is there radiator. So please for those that still believe to slow restricted water flow will cool better just believe in physics, it works on keeping you from putting 50 volts through that 3500kv motor with a 15 amp esc doesn't it?

Oh for some reason I thought those were sponsons on a 3 point hydro. They should be fine there. Try them how they are and see what happens. I've only used that style on a super vee hull and ended up doing what stadium Yamaha described in your other post. Flush with hull at the front with just a lil nub at the rear. When they were longer I was getting weird handling characteristics

[TristanJones]

Thanks heaps mate. Wish I had a hydro!
I just wanna run over 60mph even just 2 or 3 times then I'll run it on lower voltage if its unstable.

Good day all... Since there is no rudder with 4 water pick ups, I made this. Prop wash water pickup.
I bent the brass tube (ID 4mm, OD 5mm) using tube bender and the bracket were made using 3D printer.
The water flow was fast. But, the drag, not sure.
Only I'm not sure whether current inlet mouth is the at its best position or not.
Feel free to comment and suggest.
