Nice Job Wayne! So I just became a VolvoPenta Owner. I enjoyed your video and will be sure to check out more of them. I've subscribed and now it's time to get out there and work on mine. Cheer's!!!!
While I'm a retired mechanic, I don't get into the stern drive but I have a customer who's boat has the 5.7 and I have always serviced, summerize and winterized it. I didn't do it this year due to health issues....prostate crap, but he used it this year and apparantly overheated it. He thinks it's that impeller. Now I know where it is, I told him to bring me the boat and I'll do it. Thanks.
Wayne, Thanks for the nice detailed instructions on changing your impeller. I am glad everything went smoothly after you got the right parts. I am a big fan of using antisieze on the bolts when you re install them. It makes the process of removing them much safer/easier for the next time. I think it is also worthwhile trying to research the torque numbers for the bolts. They should be out there somewhere on the net. I-boats forum has some numbers for Volvo impeller housings at 29 ft/lbs. The electronic torque wrenches for these small jobs are a good way to go.
I haven’t ever used anti-seize or loctite but I was contemplating their use in this application. In the past when I’ve done automotive work I usually got pretty close with my “guessing” but I really should get a torque wrench someday!
Just discovered your channel. I dont comment often on videos but I had to give you a shout out. Great video, great info and just very well done! Thanks
Thank you for posting this video. I am having an issue on a new-to-me 20+ year old boat with the Volvo Penta 5.7 where the engine does not appear to be sucking in any seawater which leads to it getting hot quickly. If I have it attached to the dock water hose it works fine and the water circulates and the engine cools down. The impeller housing looks exactly like yours and comes apart the same way as I was able to remove it today. The impeller looked to be in ok shape but I ordered a replacement one anyway because I do not know how old it is. It looked to me like the inlet should be at the top and the bottom hose goes up to the thermostat housing but I am sure it was installed the opposite way when I removed the hoses. I tried it both ways and neither caused any water to circulate as I could tell because I disconnected the top of the hose by the thermostat. I ran the dock water backwards through the inlet hose and I could feel it coming out the inlet holes in the drive unit so I don't think it is clogged or blocked. Is there something in the drive unit that forces the water through the system or is it just sucked in from this pump/impeller? Is the inlet side the top? Thank you for any advice.
I think... think that my inlet hose is the lower one and then the impeller pumps it up to the thermostat housing - but I’m not positive. Potential issues could be: 1. Wrong impeller (like I bought) so that it doesn’t quite push water through the system 2. Bad thermostat 3. Clogged or bad manifolds etc. Good luck!
Great video with an nice amount of humility and humour, I need to do my pair of VP 5.7’s this fall. I understood there was a second O ring around the end of the shaft that drives the impeller but according to your video not so?
Another thing you can do to help the impeller prime….after it’s installed disconnect the hose that goes from the impeller housing to the thermostat housing at the thermostat housing. Then fill this hose with water & some dish soap mixed in till it’s more or less full. Next reconnect this hose at the thermostat housing. Then hook up your water muffs in the lower unit & turn on the water before starting the engine. This method makes the rubber impeller get water & some lubricant right away. It takes a bit of time for the water to travel from the water intakes, to the upper gear housing, thru the hoses in the transom mount thru the ps cooler on the back side engine all the way to the impeller housing on the crankshaft.
Thanks for sharing this info, good stuff. I'd love to see an oil change video on this engine to see how hard it is to access the filter. Oh, then you can do a filter relocation kit install video. If you can keep one step ahead of me then I'll always know what I'm getting myself into ahead of time! ;-)
Thanks for the video. My 2003 5.7 GL needed a 14 mm (slightly small that 9/16) to remove the bracket bolts. I'm about to try and remove water pump cover with 8 mm.
Have you had to buy a bunch of new tools to work on your boats, or is it mostly just the standard stuff the average person would have lying around the garage?
Wayne, first, thanks fkr the videos! I have "new to me" 2004 Funship 214. Volvo Penta 5.7. I changed the impeller because I've been having overheating when running over 3000 rpm's. Overheating, along with a drip from the bottom of the pump housing. I was hoping the new o ring would fix the drip but it did not. Do you think i need to replace the entire pump housing to stop the drip (and the over heating). Thanks in advance And thanks again for the videos! Very informative and entertaining. Phil
Chasing down overheat issues can be tricky. There shouldn't be any dripping - so tackle that first then if there is still an issue, check to see if the one manifold or riser is hotter than the other. If so, they might be needing a change as well. Good luck!
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 Wayne thanks for the great videos as a first time boat owner I can say you have been a big help to me . Question, should my thermostat housing Be warm to the touch ? I recently replaced my impeller and I’m seeing there is a leak on my water pump . Going to have to replace the whole thing .Should I replace the thermostat housing and thermostat also ?
Since bolts are not magnetic I've always used a little bit of plumber's putty on the bolt heads and then pushed into the socket I've done this for years for numerous applications automotive and Marine I keep a tub in my toolbox
I believe I cross referenced the numbers on the engine with several parts suppliers because there's several that were used for the GM V8 VolvoPenta engine.
Hello Wayne ! I just received my impeller kit and will be attempting to change it out prior to summer. How didi you know that it was the wrong kit ? I have a 5.7L. Thanks
@@WayneTheBoatGuy , SUCCESS. I was able to replace the impeller AFTER twisting off the small brass screws off the impeller housing AND a mysterious vanishing act for the bolt holding the bracket on ????? Also, the O-Ring that came with the kit would not fit into the groove and I had to go get one that fit. Thanks for your help.
Hello Friend What is the difference between kit 21951346 and kit 21951348? apparently the impellers are the same measurements... I bought kit 21951346 because it was in my engine, but when the new kit arrived, I saw in the manual that it could not be applied to my engine, there was an image showing the type of housing that could not, which by the way was the same as mine and yours too! I'm from Brazil, sorry if the translation is confusing, I'm using the translator. Thanks.
I could not determine exact reasons why the one kit is wrong, but I think it has to do with some very minor differences in measurements which might be the difference between it working as intended and not working well.
Might be a dumb question can’t find a solid answer. My water pump on the front bottoms pulley gets extremely hot almost right away when the boat is running in the water. Doesn’t seem normal but not sure?
I am not 100% positive, but that doesn't seem right to me. Typically the 'raw' water is coming in to the engine at that location, so it should be cooler than it is once it circulates through the engine. I wonder if maybe the impeller is slightly oversized and rubbing the housing so hard that it is heating it up.
@@WayneTheBoatGuy yea can’t find a clear answer. It over heated once but haven’t been able to duplicate. Either way I think it is worth taking the impeller out to have a look. Thanks to your video it seems pretty simple. I will update if I find anything
It can be tricky! Relying on product description on Amazon etc. isn't very reliable. I think I ended up looking mine up on a VolvoPenta parts site and then checking it with a few other resources. I purchased a wrong one and the information sheet specifically said that it wasn't for my engine specification number.
@@WayneTheBoatGuy thanks for including the bolt sizes in this, very helpful. to make sure things are working, where do you look for the water to exit the boat?
If they're 'bad' they have cracks, missing chunks, or are hardened up and stay deformed once removed from the housing. This one was very flexible, not damaged in any way, and was able to spring back into its original shape quickly.
I sucked mud in my volvo pinta overheated tried starting it over and over like an idiot until the battery died then once it was toed in I charged the batteries tried to start and now it just clicks.

@@WayneTheBoatGuy I always use anti-seize but avoid loctite. Loctite is like a glue that makes the bolts more difficult to remove.
Another great video Wayne. I like your sense of humor along the way too.
I like your torque spec... "Quite tight!" I've used that one many times!
Thanks! - lol - that's how I roll in most situations.
Winters done! Float that boat! Have Fun!!!
My big oak trees have finally stopped shedding - hope to splash in the next few days!!

I think some models might have that, but mine does not. There are many subtle differences between models and years.
Thank you, this is the best and most helpful video I have watched
Glad it was helpful!

Hey Wayne great video. My impellor came out with a small groove in the middle would this be caused by a damaged pump or running dr
Have you had to buy a bunch of new tools to work on your boats, or is it mostly just the standard stuff the average person would have lying around the garage?
I’ve only bought a few tools so far!
Just a thought, place a big towel on the bottom, it will catch a bolt from bouncing around if it was dropped.

The thermostat is designed to open when the temp is warm - so when the engine is operating at temp it will be warm.
Will the sx sterndrive have and impeller in it I changed out the one on the front of the motor and it's not pumping water out the exhaust
Since bolts are not magnetic I've always used a little bit of plumber's putty on the bolt heads and then pushed into the socket I've done this for years for numerous applications automotive and Marine I keep a tub in my toolbox
Good tip!
Hello sir.
I have a volvo penta 5.7 v8. Boat is a 2000 18 foot 188. How did you find which impeller you needed?
I believe I cross referenced the numbers on the engine with several parts suppliers because there's several that were used for the GM V8 VolvoPenta engine.
Well put together video. Thanks
Glad you enjoyed it!
Thanks for the great video !
My pleasure - thanks for watching and commenting!!
Hello Wayne ! I just received my impeller kit and will be attempting to change it out prior to summer. How didi you know that it was the wrong kit ? I have a 5.7L. Thanks
There was an info booklet in the box that said not to use it on certain model number engines.
@@WayneTheBoatGuy , SUCCESS. I was able to replace the impeller AFTER twisting off the small brass screws off the impeller housing AND a mysterious vanishing act for the bolt holding the bracket on ????? Also, the O-Ring that came with the kit would not fit into the groove and I had to go get one that fit. Thanks for your help.
At 12:54 you’re talking about checking the water flow. What’s the best way to do that? I have the 4.3 GL-A.
I think I checked it by having one of the hoses disconnected that flows out to the exhaust.
@@WayneTheBoatGuy well, I’ll look into that.

Great video, how often do I have to do this.
Most people recommend every couple years.

@@WayneTheBoatGuy thanks for including the bolt sizes in this, very helpful. to make sure things are working, where do you look for the water to exit the boat?
You CAN replace that pump with the boat on the water if you used a plug on the water inlet no need to take the boat out
How would you know if its bad or not
If they're 'bad' they have cracks, missing chunks, or are hardened up and stay deformed once removed from the housing. This one was very flexible, not damaged in any way, and was able to spring back into its original shape quickly.
Much easier for me with the firewall board removed.
Yeah - each setup is a little different depending on the boat size/layout and manufacturer.
So was it leaking
nope
I sucked mud in my volvo pinta overheated tried starting it over and over like an idiot until the battery died then once it was toed in I charged the batteries tried to start and now it just clicks.
That sounds bad! I would start by pulling some of the hoses to flush them out and checking the impeller.
