Installation Guide

  1. Ensure the engine is off, the battery is disconnected, and the motor is cool to the touch.
  2. Remove the lower unit (gearcase) from the outboard's driveshaft housing. This typically requires removing several bolts.
  3. Locate the water pump assembly on top of the lower unit and unbolt the housing.
  4. Carefully remove the old impeller, wear plate, gaskets, and cup, taking note of their orientation.
  5. Thoroughly clean the mating surfaces to remove any old gasket material or debris.
  6. Install the new gasket, wear plate, and insert cup, ensuring they are seated correctly.
  7. Slide the new woodruff key onto the driveshaft and then install the new impeller, turning the driveshaft clockwise to bend the vanes correctly inside the housing.
  8. Secure the new water pump housing with the provided bolts, tightening them to the manufacturer's specified torque.
  9. Re-install the lower unit onto the outboard motor.
  10. Once fully assembled, reconnect the battery and test the engine in water, confirming a steady water stream from the tell-tale outlet.

Troubleshooting & FAQ

How can I confirm this kit fits my Yamaha engine?
Our compatibility table lists specific Yamaha models, years, and horsepower ratings. Please cross-reference your engine model with the 'Compatible Engine Models' table. For additional help, you can use the Yamaha Serial Number Guide linked above to identify your engine details accurately.

What are the signs of a failing water pump?
Common symptoms include the engine overheating, a weak or inconsistent water stream from the 'tell-tale' outlet, or a high-temperature warning alarm. Reduced engine performance can also be a sign of poor cooling.

How often should I replace my water pump impeller?
For most outboard motors, it is recommended to inspect the water pump and replace the impeller every 1-2 years or every 100-200 hours of use. Service intervals can vary based on operating conditions like saltwater use, high-RPM running, or operation in debris-heavy water.

Not indestructible but pretty darn tuff for sure!
Size: Large, Color: Blue
I would have maybe given a better rating if they hadn’t lied about it being indestructible and recommended it for my dogs size range! It didn’t last the first day. However my dog may be a bit above average when it comes to his relationship with the balls! It’s an issue and he should probably be in a 12 step program of some kind. But we all have our vices right and his is balls. All of them he needs em and he never stops joining for them and the stronger they are the more he’s driven to defeat it! So now that you have full disclosure from me. The ball is still in his box and it’s still round and mostly intact and that’s after several months! The part that didn’t last the first day was the squeaker! Poor little dude! If he would have just stayed quite it. But he didn’t and Bo dog knew he was in there! And made short work of him. Other than that. The ball pretty dang tough! But it’s not indestructible is it a big deal. Well in this world of way to many choices and then having to find the few that will tell you honestly what your getting and are not over stating their product! Just to get your money. And couldn’t care less about the quality! It sucks that we have to navigate all the crap to find the few decent things available. So it most certainly does matter! And I say that for their benefit the most hopefully! Because people are craving and constantly looking for a company that just makes the effort to put out the best they can. And tell you the honest description of what they have. That stands behind their work and puts more effort into quality then they do into profit. With the faith that the quality and integrity in their company will end up bring them the profits they can be proud of and know that they earned! Honestly! Is this company one of those! I don’t know? It’s not clear and in their defense I never reported the sneaky man’s demise on day one! I expected that. But indestructible is a descriptive word that has a very specific meaning. And when it’s used in a manner that it was! Then you’ve set yourself up to fail as there are very few things that meet that description! And I know I’m picking hairs here. But it’s words that get used like that wich makes one appear to have not met the standard they wanted to! And maybe you don’t realize its impact on your overall until it’s far down the road! Can it be said better. Sure . Always room for improvement. But I would certainly remove the claim that’s just unreasonable to expect. If I wanted to use the benifit the does have to offer perhaps I would have said this ball is the closest thing to indestructible we’ve made so far. That’s statement tell me that they are not claiming it is but that it’s pretty tough! And it with out exact words tells you these guys must take honesty seriously or they wouldn’t have chosen to claim the accurate step below. And that lets me know that they hold themselves to a standard that they obviously respect their customers and they don’t take them for granted that’s integrity right there and there’s just not enough of it o. This world today! Seems to me that there are a few that are really close to it though. Maybe so close it’s worth the time to just go ahead and say it. If my gut feeling is right then it’s absolutely worth the time! Do I recommend the item absolutely it’s as tough as nails! And if you hate the squeaky part. Then don’t worry it won’t last long if your dogs like mine. Or you can take the little dude out when the dogs sleeping! And I’m going to add a star because when I look at it in the wider view I’ve been a bit harder then is justified I believe. Their. Our lives today are not as good as they once were and should be! Because of our bad habit of not holding ourselves to the standards we are capable of and rather settling for what’s out there at the time. Because of many reasons right. What’s the point. Or it’s not going to change a thing. Or that as good as it needs to be. Don’t want to seem so picky and all the justification we inject in the place of our potential. That’s had a vey negative effect across the board! And we’re losing so much more then quality dog toys as a result. When we let or standards drop due to whatever reasons as a civilization then are standards drop. And that’s all you should need to know. To understand where that leads! And we only do ourselves the disservice and loss that comes from those choices. So look around and don’t hesitate to. All out that when you see it. Just try and come from a place that’s not to tear things down but to remind them of what they are really capable of! And how much we all need to hold ourselves to the highest standard we are capable of! And stop justifying excepting less! And then we see the results from that rather than the other.

MUST BUY! For large Dogs Safe & Fun! 100lb Dutch shepherd loves this
Size: Large, Color: Blue, Size: Large, Color: Blue
I have 100 pound Dutch Shepherd who likes to chew and he goes through toys pretty quickly. This one he has been chewing on for hours and has not made a dent, not one!! he loves it. He bounces it. It’s very bouncy. I love that about it the engagement with it is great! noise level. It makes some noise. I’ve got wood floors so you can hear it bouncing and the squeak is pretty loud, which is fine with me. It doesn’t bother me. My pet really really enjoys this a lot. I think this is an amazing value for the money because I’ve spent more money on other toys and they fell apart within a day. I think it’s a safe toy because he’s not got a little hard plastic pieces that are coming off of it. It does not break apart very easily and the size is good. it fits in the palm of my hand so it’s pretty good size ball for him. It’s big enough. He cannot swallow it, but he can fit it in his mouth. I think the thing that I like the most about it and he enjoys is that when he drops it, it bounces and he can chase it. Pet enjoyment 10 out of 10 engagement 10 out of 10. I feel it’s very safe dog friendly absolutely must buy hands-down. You will not be disappointed. It’s made of a very strong. I would say rubber and it’s super easy to clean. Just toss it in the sink. Wash it off with soap and water rinse it. It’s good to go. I’m running to buy another one right now as we speak so just in case he loses it, he’ll have a backup.

Great, solid toy safe for my dog
Size: Large, Color: Blue, Size: Large, Color: Blue
This ball is great! My pit bull love toys, especially ones with squeakers, but she’s a power chewer and trashes them almost immediately. Since she’s got a history of swallowing foreign bodies, this means she’s rarely been able to have toys, and when she does get them, it’s short lived. She LOVES this ball and it’s already lasted multiple weeks with no signs of any damage, despite the fact she carries it everywhere and chews on it daily. We don’t have to worry about her safety with this toy, because it’s large and tough enough she can’t swallow anything. It hasn’t lost its squeak either despite all her tough love. She loves to play with it and we’re getting more of them asap so she has a backup if this one gets lost or eventually does break.

Truly indestructible
Size: Large, Color: Blue
They are not kidding, this ball is truly indestructible. I've gotten several for my dogs so they have plenty to share. Two of my dogs are beyond super chewers (bully breeds). One of the balls is missing the section that's glued into most of them, but the structure has still held up. And my dogs LOVE them.

Tough STINKY ball
Size: Large, Color: Red
This ball is the only one I've found that my dog can not destroy in seconds. He can chew on it for a few weeks before he works a hole in it. That's the good part. The bad side is the horrible smell! It doesn't seem to bother him, but it is horrible to my nose. It is so awful that I tried soaking it and dish soap and vinegar water overnight to see if I could make it go away. It was a little bit better but still stunk. Anybody got other suggestions on what could make the smell go away?
