Thank you kind sir :-))

Before cutting holes, check out the airbox idea that seems to be working well. Details on the Xtreme forum (http://www.xtremercboats.com/phpBB/viewtopic.php?f=1&t=25092&hilit=airbox)

To late lol %% already cut the holes
iv seen these air boxs and am trying to make one fit in my blata powered mhz chief :-))

Excellent photos Kurt and coming together nicely and quickly :-)) :-))
Can I ask how you have secured the radio box in place?
Cheers
Craig

Thanks craig...radio box is held in place with aeroplane elastic bands mate,on the outside of the radio box is 2 slots which a 10 mm bolts fits in.i bolt these through the stingers and slid the box down ,that stops the box from moving,then hold it in place with elastic band..less holes.less water and radio box can be removed in less than 1 minute :-)) please look at pics i have added .........
iv now done the stuffing tube,all in place and held there with jr weld also place carbon brace on top,,,,,,, ;)
-
Thank you Kurt for your excellent explanation.
It is good I think that this was clarified because the earlier initial photos may have had folks thinking that you had in fact fitted two bolts both sides through the stingers and into the sides of the box (potential leak source), etc.
However the clever way that you have done it has the best of both worlds. Easy removal, secure and not risking water leaks via the mounting method.
Cracking good stuff and thanks for sharing this with us :-))

Oh and forgot to say, very good to see the stuffing tube all in situ looking very neat and strong.

Hi Ian can you explain the principles of this air box and how it works,advantages over the usual way of venting the hull etc as i dont read Dutch lol.

Sorry Mart hadn't seen this.
As I understand it the idea is to provide the motor with "cleaner, cooler" air as water spray drops out of suspension as air travels through the air box and air drawn from the outside of boat should be cooler as it has not had to deal with heat from the motor and pipe.
-
Thanks Ian :-)) ,i know ive personally tried using air dams inside cowls and under the deck so when air enters the vents the air is pushed down into the bottom of the hull directly in front of the engine to feed the cool air to the motor and seems to help.First time ive seen this idea though,thanks for sharing.
