Well, I got the parts to do the h20 pump on my '05 Merc. today and got it knocked out no problem thanks to the help of Bubbakat. I heard that Mercsshift using the splined shaft that turns the prop. Well, apparenlty they changed that becausemine has a separate shift shaft at the front of the foot that you have to screw loose in order to drop the foot down. All I had to replace was the impeller and water flow is a lot stronger now with themuffs on it. Also changed out the plugs, gapped them at 0.040 and changed lower unit oil. Now she's ready to hit the water. Might get out this weekend after all. Sure does crank a lot easier with them new plugs in it. Thanks Bubbakat!
