excel inflatable floor 0.7 bar

[chrissd330]

Reading my manual on the Excel sd 330,it says to inflate the floor to 0.7 bar pressure ,i got as far as 0.25 and that was hard,should i go to 0.7 bar pressure,seems a lot to me.why so hard just for the floor.

I would be phone them and ask the question of the excel team, however air flops are usually a higher pressure than tubes.

Have a look on the Transom plate, that should tell you

Yep, floor is high pressure so 0.7bar is spot on.

Floor gives a huge amount of rigidity to the sib, floppy floor equals rubbish performance

What was morning pressure topped to, will not remain same in the afternoon, will need a re inflation if wanting same morning water performance. Heat and atmospheric issues.

Hi,thanks everyone,still learning about SIBS,never realized just how important the inflatable floor is to the rigidity of the boat and performance,and if its being used all day ill come in for a top up of air for it,unless i`m just fishing close in then i don`t suppose it matters.
Just hope its strong enough to take the 0.7 bar,and that the auto shut off and gauge is accurate on my Genovo pump(the yellow one with digital readout).
Thanks again
Chris

Even with just a few psi less than it should be, air floor boats are terrible. A bouncy floor can ruin the boat, water over the back, water over the front, might not even plane etc etc

Its important that you top up the floor and tubes once the boat has been in the water for 10 mins, the temperature change can cause a huge pressure drop in the boat.

Sorry, cant give advice on your pump, but I use the bravo ones and they are spot on. The only way to find out is to try it

[bingosucks]

sounds about right i never exploded mine !

Mine takes 0.75 BAR (11psi). Floor pressure is essential to get right for planing performance - not an issue at displacement speeds. I have to be careful - my pumping "system" is a SCUBA cylinder and can fill to 230 BAR

[chrissd330]

Looks like i am going to have to take the pump with me,may need a seperate pressure gauge to check against the pump reading,never knew there was so much to it,thanks again for all your help,0.7 bar seems common for inflatable floors looking on here,looking for a launching spot now.
Willk be carefull with that cylinder.230 bar my pump goes to 0.8 bar I believe.

[beerbelly]

mine is 11.2 psi too I don't think my bravo pump would go much higher tho as the last half a pound of pressure and the pump slows down and seems as if 11.2 is as much as it can go to

[chrissd330]

I only bought my pump a week ago,not had it above 0.25 bar yet.

[claretcass]

Thanks for that everybody, never realised how vital it is to inflate the floor correctly to ensure performance.
I have a new Excel SL260 and on the 3 occasions I have been out I have not been paying much attention to it, will now
Thanks again..

As above Excel high pressure air deck is exactly that. Stiff as a board and thats what is required.

Snap on your outfit, Excel 330 + Tohatsu 9.8

[chrissd330]

Thanks SIBer ,whats the grey board that came with it,does it go under the floor where the 2 straps are at the front

Oh man, no instructions then?!

That the thrust board - no board, no workie. It fits under the floor and above the inflatable keel. You DO have an inflatable keel? It will have an odd pressure too.

[chrissd330]

keel 0.4 bar,thrust board,now I know, didn`t see that in manual.Thanks for that.

Does anyone use a bravo stirrup pump for their air floor?

I can get to the point where I have to push down with all of my weight on the pump and air goes in a tiny bit at a time.

The gauge only shows the pressure on the down pump and I can't really read it. Is it likely to be about the right air pressure at this point?

It dependes on which model you have, they can deliver anywhere from 3 to 11psi.

It's a bravo 6 which claims to deliver 8.7 psi..
