I think that you have the wrong type of suction hose. The hose that you show would appear to be soft wall, and not good against suction collapse.
This hose must be collapse proof when used on the suction side.
*************************************
In reading back through your thread here, I noticed a few things:
I'd get rid of those standard band clamps on your drive shaft bellows. Use the Euro style band clamps in place of those cut worm screw bands. The fully cut bands have a tendency to grab and pull on the bellows material while being tightened up.
If this style clamp pulls on the material, it may not seal as well.
The OEM Volvo Penta are always the Euro style, and are smooth on the interior of the band.
Also, and just an FYI.... I see red RTV oozing from the water neck fitting.
This is a special beaded gasket with the bead to be facing downward against the pivot tube.
The upper side can be sealed against the water neck fitting, and technically you could also seal the underside of the gasket surface.... but the flat surface ONLY!
The actual beaded area must be lubricated since it actually rotates against the top of the pivot tube.
The lower pivot tube O-ring rotates 1:1 with the pivot tube..... so nothing needs to be used here.
