Installation Guide

  1. Disconnect the negative battery cable and shift the outboard into the neutral position.
  2. Remove the lower unit (gearcase) by unfastening the bolts that connect it to the engine's midsection. You may also need to disconnect the speedometer tube and shift linkage.
  3. With the lower unit on a suitable workbench, remove the bolts securing the water pump housing cover.
  4. Carefully lift the old water pump housing, impeller, and wear plate off the driveshaft, observing the orientation of the impeller vanes.
  5. Thoroughly clean the driveshaft and the housing mounting surface, ensuring all old gasket material and debris are removed.
  6. Install the new gaskets, wear plate, and driveshaft key included in the kit.
  7. Slide the new impeller onto the driveshaft. While turning the driveshaft clockwise, lower the new housing over the impeller to correctly seat the vanes.
  8. Press the housing down firmly and tighten the bolts to the manufacturer-specified torque.
  9. Reinstall the lower unit, carefully aligning the driveshaft, water tube, and shift shaft before securing it.
  10. Reconnect the battery and test the engine with a reliable water source (like flushing muffs) to confirm proper water flow from the telltale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Mercury engine?
A: Verify your engine's serial number. This kit is made for 75-115 HP 4-stroke models with serial numbers 2B094996 and up, and 150 HP EFI models with serials 1B905505 and up. You should also cross-reference your existing part number with 8M0094529, 8M0094259, or 8M0057715 to ensure a match.

Q: What are the signs my water pump is failing and needs replacement?
A: Key symptoms include your engine overheating at idle or low speeds, a weak or inconsistent water stream from the "telltale" outlet, or discovering the impeller is brittle, cracked, or has missing vanes during a routine inspection.

Q: How often should the water pump impeller be replaced?
A: As part of preventative maintenance, we recommend inspecting and replacing the water pump impeller and gaskets every 100 operating hours or annually, whichever comes first, even with low usage.

Updated title: Not for a power chewer
Size: Dog Rope Toy - M
Update: I had to cut the ball off the same day I wrote this review. Two days later, the yellow rope was totally unraveled and I had to throw it away. She got maybe 3 days of play with this toy. Do not buy this toy if you have a larger dog that chews a lot. I will say our dog loved this toy the moment she started playing with it. But the toy doesn't last long with our superchewer. I was hoping to use it for some games of tug, and while we're at it get her teeth cleaned by the spikey red ball. The listing includes "large" dogs. My large dog (11 m/o Bernese puppy) had this toy broken within the first 10 minutes. The red pieces are a pretty lightweight plastic that she just broke apart completely, specifically the bone on the "handle". The ball is lasting a little longer, but she put a hole in it. We will probably need to cut the ball off as well because she'll chew it up and swallow it if we're not careful, and then she'll need (another) surgery. The positive is that she loves chewing on rope and the rope pieces seem pretty sturdy. We still play tug with the ropes, but this one I will probably just give to her as a chew toy. We found a more durable ball on a rope toy at Target for a little bit less.

This toy will not hold up
Size: Dog Rope Toy - M
I bought this for my heavy chewer. The plastic pieces lasted about 15 minutes. She is an Italian Mastiff, but she is only 7 months old. I expected more from a toy that was rated as 'tough'.

Best and toughest dog toy on the market 4 all breeds and sized dogs
Size: Large, Size: Large
Now i know this doesnt appear to be good based off the photos but hear me out. My pitbull (and any pitbull owner will most likley know the same struggle with chew toys) is an extrememly tough ans agressive chewer! Every toy i would purchase for him from rubber ones to rope ones, enormous raw hides, oversized balls thinking it would be hard for him to bite believing that would increase its life, it did not. None of the toys lasted for more than a few HOURS!!! And that was when he was being easy with them! I was on the line of stopping biying him toys and letting him just chew sticks, but then one day in a coversation with my plumber and familt friend he mentioned trying kong brand dog toys. I didnt have anything to lose besides more money and an hour of entertainment for my dog so i decided to try them. I bought 3 different kong brand toys. A tug of war one that was rope with kong rubber grip handled ends, a weird ball like toy that was able to add peanut butter in a small hole and this toy. Amazed the tug of war toy(handles only) even though fairly thin lasted over 3 days!! And thats huuuuge for him with toys. Then the little peanut butter ball thing lasted about a week! I was sold. But then he finally got to try this ball with tug of war handles that contains a tennis ball when it finally is destroyed as a bonus toy and it even squeeks and the swueeker was even guarded by the rubber so it wasnt crushed immediatley! Now afyer seeing the picture of said ball it is destroyed now but it lasted many tug of wars with him and him gnawinf on it for hours every day. The kicker is i bought it roughly around september 16th, it is now JANUARY 21st!!!!! The ball has now lasted him approximately 4months 5days! Thats an insane increse of chew life for any pitbull especially mine. And it ximes in 2 sizes. The large is a little bigger than a large cantelope or slightly smaller than a basketball. And they have a smaller version for small breed heavy chewers!! I couldnt be more pleased with this purchase and will definatley be ordering 3 more ASAP considering his prob only has another week or 2 left. The only negatives are 1, when they do chew off the handles tou cant play tug of war any more and 2 that when they finally get into the main cavity where they can actually start chewing off little bits of it they emd up all over the place, bunchesmof little rubber nubs but its easy to clean. So if you have an extremely heavy chewer as i do and are looking for a toy that is worth the money and will last your dog a good time and that they will love(my dogs fav toy hes ever had) and u want it to squeek and have a bonus toy inside of it to hold them over til the next one arrives when they ruin it, then trust me! BUY KONG CHEW TOYS. specifically THIS TOY!! Best dog brand and toy on the market. Ajd its safe and if im not mistaken harmful chemical and bpa free so ur pups can chew safely. And it cleans their teeth as a bonus because of the tough rubber!! Its so worth it. only recommendation. Buy atleast 1 large 1 and one small one if u have a medium-large dog. If their small then probably only the small one or any other kong toy. If they're light chewers u probably will mever have to buy another chew toy again! Its that good and strong yet still flexible enough to squeek it!! Hope this review helps you and encourages u to buy this toy and brand over any other!!!

Purrrfect for a Pitbull or Am Staff Terrier
Size: Large, Size: Large
Large size Dog: Am Staff about 50-55 lbs She ruin all her toys in less than 3-5 minutes except this one. Again, we use this toys with guidance and support. Cons: Definitely built to last but must not be left unattended because we all know what our pitbull and Am Staff is capable of doing with their teeth. It has many feature, squeaky sections the sensory of the ball inside, weighted, and puncture proof, top and bottom option to carry this dog during a fetch game. Easy to clean. Cons: if left unattended this is not a chewing proof toy for 6-8 hours. That is not what is made for. This is an engagement toy you have to do with your fur friend.

Entertaining and durable
Size: Large
Great toy and quality. My dog that was a bit of a ruffian with his toys loved this toy. It lasted through his wild days so I bought my current baby one. Unfortunately she hates it. She wants the ball trapped inside but hates the sound of the outer and won't go near it or even let it touch her. Granted she is a bit...eccentric. All larger dogs I have ever seen with one love it. It is very durable. Really serious chewers may need supervision but average big chewers should be fine.
