Thanks for the video. I know it's an easy swap, but its always nice to watch a quick video to make sure everythign is being doen right and I'm getting all the nuances. :)
I wish you would do a video on replacing the impeller in the most poorly-engineered raw water pump in history. That would be the one on my 2002 Ski Nautique with the "Excalibur" PCM Chevy 350. The pump is nearly inaccessible due to its location between the fuel control cell and the harmonic balancer pulley. One of the mounting bracket bolts has to be removed using an open-end wrench because it is located behind the pump pulley. Of course, the tight quarters limit the wrench to less than one sixth of a turn, so removing this bolt takes quite a while. Once the mounting bracket is loose, and I have cleaned up the blood from removing the inlet and outlet hoses, the pump and mounting btacket assembly must be maneuvered back under the engine to the only spot it can be removed, from the area between the two left side engine mounts. The best part, though, is trying to wrangle the new impeller into the housing. I always allow a couple of days to do this. I use a couple of hose clamps to compress the impeller blades, and lube the blades with dish soap. It usually requires 50 to 60 attempts to find the magic combination that gets the impeller in without pushing the woodruff key out of the slot in the shaft. I'm up to 30 attempts tonight, and I'm quitting for the day.
Your comment couldn’t be more true about the aftermarket impellers is not keeping up. They fall apart after 30 to 50 hours. I wish I could upload the picture of the one I just pulled out. There wasn’t one fin left on it and it has 32 hours on it. I will be ordering PCM parts from now on.
so many vids here and on all of youtube on HT install an impeller. I got it, so dang easy. Do you have a video on rebuilding a G21 raw water pump. 92 PCM 351 engine. bearings, clips, seals, etc.... take it apart, put it back together? maybe just an exploded view dwg? what goes where, what order, HT get the dang thing apart. please help a boater out here.
