How to change the impeller on a Volvo Penta Gen 5 engine.
For your convenience, I have provided Amazon Affiliate links below for items discussed in the video. What does affiliate link mean? I may earn a small (much appreciated!) commission from Amazon for providing the link, but it costs you nothing.
Impeller kit 21700445 (the Genuine Volvo Penta part and link I personally ordered from): https://amzlink.to/az0j9AfDfi3jL
Or here is a link if you want to try your luck on a less expensive aftermarket impeller. Although the manufacturer used/stole still images from my video, I can not endorse it one way or the other (lol)! : https://amzlink.to/az0C0eolmuZw4
1/2×28 to 3/4×16 thread adapter: https://amzlink.to/az0DYRSeWn0To or https://amzlink.to/az0yic7P8xDLv (they are the same thing, but one may be better priced). I suggest adding both to your cart and keeping the best option based on price and availability.
As for the bolt, I ordered it from McMaster-Carr, part number 92620A131. Sorry, they are not set up to sell on Amazon or to provide a direct link. So just go to their website (https://www.mcmaster.com) and search for the part number. Their site says it is not fully threaded, but it did arrive fully threaded. And since there was probably still at least an inch of threads left when I pulled it, a 2 inch (92620A128) or 2.5 inch (92620A129) long bolt should also work. Probably even a 1.5 inch (92620A127)? The shorter bolts are priced better than the 3 inch one. A note on this bolt – it will corrode over time. So I suggest hitting it with WD-40 or some type of oil to help prevent this.
A different adapter type could be used as long as the outer threads match the impeller (3/4×16). Then of course you would need a different bolt to match the internal threads.

how did you get that manual service
One of many great videos Iowa Buckeye! I did order the bolt from McMaster-Carr from your link and it did arrive fully threaded. There was no way that I would have been able to pull mine without it based on the location. Putting the new impeller in, I found it helpful to wrap it tightly with a Velcro strap forcing the fins in the desired direction. For winterization, I am wondering about your thoughts on disconnecting the negative to the batteries vs just turning the disconnect switches. I have 3 batteries (house, dedicated starter and bow thruster). Thanks so much for giving us all the confidence to do simple maintenance. These engines are so much easier than the old ones.
Amazing video same engine same install. Here's a tip the 2 aka thermostat/ water pressure regulator valves on the exhaust manifold have been upgraded to a better part the plastic melts .
Nice video, but in my case I tried to pull with a small plier and came right off, very little effort and not much space to pull it out, maybe 3~4 inches. Otherwise I would lose a nice weekend on the water.
Nice video. Thank you for being thorough but succinct!
Last time I used some silicone grease on the impeller shaft before installing the new impeller and it made removing it significantly easier, this time around.
Great video. Very informative and very helpful. I changed mine on my Volvo penta. Looks to be almost intentional to yours. Mine was 3 years old so I decided to change it, when I pulled it nothing looked wrong with it at all. The change out went smoothly. But when I took the boat to the lake it almost immediately went to over heating. Have you or anyone ever had this problem before? I don’t think it would have debris in the system with the old impeller being in tacked when I pulled it out. And the boat was not overheating before I changed the impeller. So I am confused as to what the issue could be.
Where did you find the bolt
after how many hours do you change or should this be done before every season?
How in the world do you get yours to pop in like that? Mine won’t go last 1/4”
Two pairs needle nose pliers. Grab the impeller at 9 o'clock and 3 o'clock pull it straight out. Easy peasy lemon squeezy
I have a glastron with 5.0 Volvo penta the impeller is at the same place of motor of yours to replace it ????
Applying some Vaseline on the large rubber o ring will help it remain in place prior to installing the cover plate. Excellent video!
I installed the impeller housing after summarizing and now I hear a grinding sound and the belts don't spin… I've taken it apart 2 times now and the same result. Any ideas of why?
Hey can you tell me where is the PCV valve located?
Awesome & detailed. Thank you.
