New Prototype Water Cooling Intake

Thought I would share the unfinished version of my new Prototype Water Cooling Intake for my HK Genesis
It is essentially a 5/32 brass tube JB welded down the back of the rudder, wrapped underneath...
The ends have yet to be cut, but once done it will have a well sanded and smooth join and a nipple threaded into the top adjacent to the other nipple that is usually there.... yes..I know they already make twin water intake rudders... but they are mucho $$$ and still yeild less water than this puppy will....

Here are my theorised benefits...

• Forced Water into the tube at a 90deg angle (should increase the water line psi)
• Mounted very deep (should provide a steady flow with no air gaps)
• Integrates in parallel with current water intake
• No drilling or cutting into the hull
• Cheap (Cost me about $0.59 for the JB weld and $1.50 for the tube...)
• Less resistance on the back of the rudder as it is now round
• Will probably mount it with 2 x 90deg nipples..

Would like to get some feedback on the design...
I will post more pics when it is complete...

stay tuned..

Welcome to the board! Good to see people inventing!
Good thought,and I will be curious to see outcome... But I see two issues:
1) back of rudder needs to have crisp right angles to reduce drag
2) big hole at bottom could mean even more drag and force the nose down.

I too commend folks for tinkering and engineering, but it will have alot more drag than a standard rudder pickup. Also, i once thought the trailing edge should be rounded..............i was corrected by several................nice sharp edge as Jess pointed out already.

Looking forward to this one...
Maybe a shorter intake would help and give less upset in turns

A friend of mine done this exact mod a while back on a deep v hull & it completelly messed up the handling. Before the mod the hull run very well & fast running quite loose out the water but nice & stable. After this mod it ran with the bow very low & wet also noticably slower where it was running wet. Also didnt handle as well in turns. As been said you need sharp edges on the rear of the rudder & not curved. Removed it at the lake & the boat was back to how it was before runnimg looser & much faster. Martin.

would be great if someone made a dual water pick up :) Oh.. at a decent price !
