I have no water comming out the pee tube of the engine. I cant locate a manual. I was in some reak nasty weeds in Black Lake NY. IM willing to make repair, but dont where to begin. Is there an impella in the lower unit? I see the water intake holes. I can blow out the hose to the pee hole and through the water pump doun to the intake holes. Thats where IM lost. Thanks in advance.
