Installation Guide

Always consult your service manual for detailed instructions specific to your engine model. Professional installation is recommended.

  1. Disconnect the negative battery cable to prevent accidental starting.
  2. Place a drain pan under the lower unit and remove the gear lube drain screw to drain the oil.
  3. Remove the mounting bolts that secure the lower unit (gearcase) to the outboard's upper casing.
  4. Carefully lower and remove the gearcase from the driveshaft housing. The driveshaft will come out with it.
  5. Locate the water pump and unscrew the four bolts holding the housing in place.
  6. Slide the water pump housing up and off the driveshaft, then remove the impeller, wear plate, and old gaskets. Note the rotational direction of the old impeller fins.
  7. Thoroughly clean the mating surfaces of the pump base and housing, removing any old gasket material or debris.
  8. Install the new gasket, wear plate, and insert cup. Slide the new impeller onto the driveshaft, ensuring the key is in place.
  9. Apply a light coat of marine grease to the inside of the new housing and carefully install it over the impeller. You may need to turn the driveshaft clockwise to help the fins fold correctly.
  10. Secure the housing with the new bolts, tightening them to the manufacturer-specified torque in a crisscross pattern.
  11. Reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube align correctly. Fasten the mounting bolts.
  12. Refill the lower unit with the correct gear lube, reinstall the battery cable, and test the engine in water to confirm a strong, steady stream from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Yamaha engine?

A: The surest method is to match your engine's model and year to the "Compatible Engine Models" table. This kit is designed for a wide range of Yamaha 4-Stroke models including the F75, F90, F115, and others from 2004 and up (excluding 115B models). Cross-referencing your old part number with the OEM number 68V-W0078-01-00 or 68V-W0078-00-00 will also guarantee a correct fit.

Q: What are the common signs of a failing water pump impeller?

A: A failing impeller will compromise the engine's cooling system. Key signs include a weak or inconsistent water stream from the engine's tell-tale outlet, the engine overheating or triggering an alarm, and in some cases, a steam-like exhaust. If you notice any of these symptoms, inspect your water pump immediately.

Q: How often should this water pump kit be replaced?

A: As a preventative maintenance measure, we recommend inspecting the impeller annually and replacing the entire water pump kit every 1 to 2 years or every 100-200 hours of operation. Replacement frequency should be increased if the engine is used frequently in saltwater or in water with heavy sediment.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Mascara is good, but don’t expect the best - smudges & flakes sometimes
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
This mascara is very good for lengthening when you use the primer. I’m not sure I’ve noticed a volume/thickness increase, but have noticed lash length does look longer. I usually give it about 30 seconds for the primer to dry before using the mascara, otherwise it does clump a bit. I would also recommend wiggling both wands along your lashes during application to avoid clumps. In general I do like this, but noticed a few other important points: it will definitely run a lot if you get it wet (e.g. rain or crying), it will flake or smudge a little by the end of the day - especially if you rub your eyes, and while it does not make my eyes itch, I found it best to put in my contacts AFTER the mascara is fully dry. I’ve accidentally got some mascara a few times in my eye with the wand/trying to smooth out clumps and it totally made my contacts (daily wear type) useless after that. That all probably sounds like the mascara isn’t worth it, however I still actually like this mascara. I’d say it’s perfect for an average day’s wear, just not an extended day or in some cases. It does come off fully for me.

My Go-To Mascara for Years — Makes My Lashes Look Fuller and Longer!
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I’ve been using this mascara brand for a few years now, and it’s never let me down. This particular two-in-one (primer + mascara) combo works so well — it gives my lashes a great boost and really helps them look fuller and longer over time with consistent use. Every time I wear it, I genuinely feel more confident and put-together — it just makes me look prettier, and that’s always a plus! The primer adds volume and helps the mascara go on smoothly without clumps. It lasts well throughout the day, too. If you’re looking for a reliable mascara that delivers results and enhances your natural lashes, I definitely recommend this one!

okay so far
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
bought this because i have recently developed a sensitivity to heavy makeup around the eyes. loved the ingredients of this mascara and rates a 3 on the think dirty app (amazing app check it out!) that being said, i honestly didn’t expect any crazy results like i would with my prior mascaras (l’oréal lash paradise and maybelline lash sensational) and i was right, it took forever for me to apply a decent amount to my lashes. both sides seemed kind of dried out too, not the thick consistency that people were talking about in the reviews. the primer was dry and sort of settled in clumps around my lashes and i did the best i could to comb them out but i ended out plucking out the clumps with my finger tips. the mascara itself was very thin but no clumping, just felt dried out like i said. my lashes fell straight in a matter of half an hour. it also flaked throughout the day and i spent it entirely indoors. i rubbed my eye once or twice and my inner corner felt a little irritated but im not sure it’s because of the product itself. the packaging itself is a little bulky when applying but i guess it’s a matter of working with it. i think it’s a little pricey for what it is but i think i can work with it, given that i don’t want harsh chemicals around my eyes. i will continue to be on the hunt for a “clean” mascara that works better though

Sensitive eyes, and actual visible LASHES now.
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer, Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
I've gone through so many different mascara products to be able to try and find the ones that are going to work with my sensitive eyes. I have blonde eyelashes that stick straight out and are very long for them being blonde. I was using physicians formula for years and years and years and years and then it got to the point where they switched the formula recently? And I was not getting any desired results. On a whim I decided to buy this even though it is about 10 to $12 more than what I would normally spend and I was blown away. I love the pre mascara coating, and the mascara is just so clean and so soft... It's easy to remove stays in place! It does not budge. This is a quality product 10 and a 10 100 out of 10 if I could vote it that way. Fair-skinned fair eyebrows fair eyelashes we just want to have normal looking lashes.... That's all we ask in this product delivers!

It actually is the best
Size: 0.27 Fl Oz (Pack of 1), Style: Mascara/Lash Primer
This mascara has apparently won awards, as it should have! This is the first mascara I have ever used in 20 years of wearing mascara that doesn't smudge around my eyes. The key is obviously the primer. I'm obsessive about priming something before painting it, because it makes all the difference. No wonder it makes all the difference with makeup, too. Great applicator. Product lasts for about 5 months for me, with near-daily use. Works great all the way until the tube is empty. Also thankful of course that it is a clean brand. About to purchase for the 4th time.
