with my cut back big hub impellers the gap is hardly a millimetre...yours looks much bigger, but from my understanding that softens the hook-up a bit

yes I'll do that , impeller already at the machinery shop

We like impellers close to vanes if possible. You can use impeller spacer stainless washers/shims to space forward to adjust distance to stator hub/vanes if needed. Then if needed for pump tuning, you can also space forward, like slipping a little especially off the bottom. It is more of a fine tuning thing if the pitch, nozzle size, and engine are close match already.
