A larger pump has higher flow capacity, this is more efficient for making thrust at lower speeds than increasing pressure. Plus it allows lower blade angles for a given load which improves hookup over a smaller pump with steeper blades. Hub diameters also need to grow but Skat will wait until they need something "new" in order to sell pumps.

Not to mention that Skat thinks everything they make is made of gold.
The 83mm hub works well in the kawi triples, but you need a big motor to pull them up top.

This is my thoughts on the pump subject. @Fx1boy the 144mm pump that most (yami guys) are riding, was first intruducet in an SJ 650 with around 60hp. Then SJ 701 twin carb came, with 73hp and the same 144m pump. then people start messing with bolt on parts, porting, big bore and stroker kits and most - still rocked their 144mm pump. The waveblaster 760cc comes stock wtih a 155mm pump, to a ca. 90hp engine and a heavy hull. It made a huge diffrence going from my setup wtih a 144mm pump to a 155mm OEM pump, but remeber you gotta have a intake duct that is made for a pump of that size, else you will bump into a bottle neck effect.
Got a bit more done got the ebox mounthed with kill switch.
And a bow eye have hade the hood cranked down the last 2 days, and helpede alot with hood sitting too High with the watcon seal. Also got my chin pad from maxx and assempelt the midshaft, shaft is from cold fusion nice peice.

the max pumps dont allow the prop to sit very close to the veins and that means slippage/less hook up. the veins are quite a bit thicker on the max, which means more resistance to the flow. max pumps are not as good/efficient as skat but much cheaper. the bigger the hub, the less dead space behind the prop where unwanted turbulence is/ can be created.i would think the 155 or larger pumps should also have a relatively larger hub than the 144 pump.
Yes you a correct the watcon seal was making the hood sit high, flippede the hookes too make it fit will i hade the hood rachet strapede down for a couple of days. It workede and all is good

Hi Stefan. Will you be installing Adjustable Bindings? (foot holes). If so what type?

I like the look of the Rickter adjustable bindings as seen on You Tube video Rickter Edge 2015. I have not tried these don't know what they feel like. It would be nice to adjust where your feet stand.
