What got me into this mess was the fact that there was very little water flow out of the water indicator nipple. The hose and fittings looked old so I didn't want to mess with them. So I changed the cooling water pump. Started motor again today with muffs on, still very little flow, so I took off the hose and found a tiny rock from sand wedged in the nipple. Lessoned learned. Shifted into F and R and that seems smooth also. Next test will be on the lake. Thanks so much to everyone who contributed to helping me out. Now I just have to buy a new speed indicator fitting, mine broke off when I dropped the LU without removing the hose. Another lesson learned...
