Hi - Here is the new 25 inch fiberglass hull I just got for $50. - I want to set this one up right with some help from you guys so any suggestions respecting the set-up are welcome. Is my idea that these water pick-up's (flush hull mounted) are better than through the rudder correct? - What is the best drive hardware (for the value) for this boat in your opinions (which I highly respect). I want to go 3/16 shaft so I can have a good prop selection with a generic (cheaper) brushless motor and 60 Amp Pulso boat ESC - Thanks for all comments and help - Steve

Were you looking for a stinger outdrive or strut?

Take a look at these. http://www.offshoreelectrics.com/products.php?cat=69.
It should help steer you in the right direction. No pun intended.

Octura Inline Rudder System is my choice - http://www.offshoreelectrics.com/pro...ct-oc6str-130a - But again - What about the water pick-up for cooling ESC an motor - Is the flush hull mounted pick-up better than rudder pick-up?

Hi Steve,

Both a rudder pickup and the 'flush' mounted one have a certain amount of drag, as has anything sticking out from under the hull.
If you have a temperature sensitive set-up (on the edge, so to speak), the rudder pickup is my favourite, as it ensures flow through the system at all times, exept when you flip the boat.

A truly flush mounted pick-up, would be a brass or aluminum pipe facing forward as a pick-up and a second one facing towards the transom as outlet, both sanded flush with the hull.
This is a pressureless system that has virtually no drag and generates flow at all times.

I use a spray pick-up on my fast electrics, where the pick-up sits in the propspray in the upper right quadrant, seen from the rear.
The propspray has an average pressure of 2 Bar, so there's always flow and very, very littte drag.

Take your pick...

The faster your set-up, the less drag you'll want, to avoid handling issues when approaching the hull limit.

Thanks Jan - Spray Pick-up is for me - Looks like it will get a great flow of water - Do I have to customize such a part ? - I will check Off-Shore Electrics and such. As for a stinger outdrive or strut - I won't be racing this boat - but I want it nice and fast with the best steering capibilities - Our lake is nice and calm in the bay but there are a couple of rafts and docks so handleing is important - I shall do my homework and am learnig lots and always welcome advice - Steve

Most likely,

I made mine out of brass strip with a piece of 4mm brass tubing, angled in the correct position.
I made a cardboard template first.

The pick-up can also be a simple bent brass tube like the one in the picture, it all depends on how far it has to extend from the transom without flexing under the pressure from the spray.
My appologies for the poor quality of some pics, it's hard to see the pick-up in some, but the pics were not shot with a pick-up in mind...
Hope you get the idea.

Regards, Jan.

Thanks Jan - I see how you did it now and will make my own if I am not happy with any pre-built ones that are available on the market - Amazing Boat you have ! Since you are a racer it must have some remarkably juicy parts inside! I love the way just the prop is the only thing in the water! Take Care - Steve

Thanks Steve,

As we race in standard classes overhere, the 'amazing' part is to keep the boat running flawlessly, if you can keep running while other boats collide or have electrical or mechanical issues, you can win the race.
It's like the F1 races; you don't have to win every run, coming in second every race will win you the championchip, provided it's always another boater who wins the race...

Boat maintenance is cruicial, as we all run the same 400, 600, or 700 type motor in the various classes, just blowing off the dust prior to racing your boat won't cut it, you'll have to keep tweaking.
The pics were taken in Zwolle, where we run our boats on a large body of water, so there are always waves, which causes spectacular races and photo opportunities, but certainly not the highest lap-counts of the season.

Keep us posted on your build and amaze us with your water pick-up!

Regards, Jan.
