My speedo quit, going along at about 65 happen to look down and needle just slowly went to 0. I had this before on other rigs and it was always the hose at the splice from engine to boat pop off. This time that splice is good. Here's what I did to find the problem, at the splice I pulled hose's apart and used a water hose and squirted water into the line going to gage, gage went to 45 mph GOOD it's not the gage, squirted into line going back to engine water trickles out the pick-up hole but comes out the lower unit water drain holes and slots (not cooling water pick-up holes). Pickup hole is clear and no water comes out the line at the splice if you sqiurt it in the lower unit speedo pick-up. SOOOO I guess I have a hose off in the mid-section of the engine I assume where it the line attaches to the pick-up tube. I assume I have to drop the lower unit like I was replacing water pump correct? Will it hurt anything to leave water shooting into the mid-section of the engine for a little while?
