New lower unit last year, gauge did not register any water pressure but I figured it was most likely the gauge and ran it cause I had good flow out the p-hole. Yanked 'er out of the snow drift today and put the new gauge in, still nothing, thought maybe I had a kinked line so I disconnected it at the barb and still had nothing. I had it on the muffs, insufficient flow, something in the barb? Any other thoughts on a quick fix? I have plenty of water flow out the p hole
