Impeller Tool - Great

Yup, thats how mine fits when i tested with my spare. Havent tried my install as yet. But will see as well. Jeremy are you using dish soap for lube? I did and it was still a fight to get the impeller in.

Yes , I use dish soap to lube it up. I literally had to put all my body weight on it with my knee to get it into the tool.
 
I bought this tool and did my impellers for the first time this past weekend. It took me about 45 minutes. Piece of cake and a great invention. I can see how this could be a nightmare without, especially on my port side where you have limited access and visibility. But I agree it was a bit stubborn getting the impeller in the tool. It needed to be muscled in there. I bet it's easier when it's not as cold out and the impeller is a bit softer.

What was your attack plan for the port impeller? Top of motor or from reaching around the front of the motor? I feel I can reach around the motor with a mirror if the tool works.

This is good news. Hopefully mine works out the same.

I started from reaching around the front of the motor and quickly realized operating blind was not working out so well. I'm a smaller guy so fitting back there wasn't an issue, but i could see it being an issue for some. I then decided to lay across the top of the motor and wedge my head between the floor, gas tank and motor. It was decent visibility. I removed the raw water hose attached to the fuel cooler to get a bit better access to the impeller cover. Then it was just a bright light and a ratcheting wrench, and done... Not too bad of a job. I would almost argue changing the port side lower aftercooler zinc is more of a pain. I cut down 3 zincs to varying sizes just to get one to fit into the space you have to put a new zinc in. PIA...
 
So, my boats getting all new canvas and camper enclosure, so I cant change my impellers for a couple weeks.
Received my tool today, put a little soap on the inpeller/inside of the tool and it slid in with a little rotation in about 2 seconds. I think this will really help out. I will report my findings in a month or so
 
I changed the port impeller today. It was a fail for the tool as it was intend to be used but in the end it was very helpful. The tool with the impeller in it will not fit past a bump out on the engine block when I tried to put it into the pump. I tried many times with no luck. So I took the impeller out of the tool (which was extremely difficult to do) and when it came out the vanes stayed bent for the most part. This in turn made it very easy to slide the impeller right into the pump without the tool, zip ties or hose clamps. So the tool failed to work as intended but I will keep it. I will put the impeller into it a few days before I do the pump and the new impeller just slides right in.
 
Gave this a try today and I have to say that it worked extremely well. Getting the impeller in wasn’t bad at all. It does make inserting the key into the shaft a breeze and twisting it back out was very easy. It sort of pushes itself out once you start twisting to remove the tool.

I have the tool and use it. My Sherwood pumps use the 17000 model https://marinepumpdirect.com/two-pack-sherwood-17000k/

This impeller fits perfectly and lines up well with the Sherwood P1730C pump.

I have the 6CTA's 8.3 ms.

My marina neighbor has QSB 5.9's. She bought the impeller tool and had the problem that the tool was too small for the impleller, just as you are describing.

Are the Sherwood pumps the original model to your 8.3 manual engines? I’d like to get this tool and checking the size and fit for my original pumps on my 8.3 manual engines. thanks
 
I have replaced the original Sherwood pumps with the "new" Sherwood pump on both engines. They take the 17000 impeller.

Ok, still learning these engines. Is there a way to verify the model I have?

It’s best to call the number, tell Andy your impeller part number and he will let you know what tool you need. Email was spotty with him, I called him and he said that he would check his email and got back to me. I had 3 or 4 emails to him with no response
 
I echo what @Chris-380 said about email and responsiveness. I told him what impeller I used and he sent me the tool. FWIW, mine is gold in color. Not sure that makes a difference or not.

When you change the impeller, is there a key and a keyway? If so, then I'm pretty sure you have the Sherwood Pumps. The redesign that Sherwood did was to correct a problem with an internal seal that caused the shaft to corrode and eventually break while at speed. If your impeller shaft has splines, then you more than likely have the SBMar "upgraded" pumps by Tony Athens.

Ok I’ll look and see what the impellers the previous owner left with boat for spares. Hopefully there is a part number.
I’d like to also get the tool for the generator impeller. Anybody know what the tool part number is for that?
