i have just replaced the old blade with a new solas,was going to change the wear ring at the same time but it looks ok, new blade has 0.15-0.2mm clearance,is that too much clearance???

   At the risk of hijacking this thread that sounds like a very small grill area, eg the STX15 I pulled apart was 160hp and a 148mm pump and it had an intake area of approx 150mm 300mm with only 2 bars.

Hi guys looking at getting into the small jet game and wondering which would be a better donor ski.
I heard Kawasaki skis are the go and have found a  kawasaki zxi1100 and a Kawasaki Ultra 150 for around the same money.
If someone could give advice on the pros and cons of each that would be great.
Cheers!
