Installation Guide

  1. Safety First: Before starting, disconnect the spark plug wires and the battery to prevent accidental starting.
  2. Access the Lower Unit: Shift the outboard into forward gear. Remove the bolts securing the lower unit (gearcase) to the upper leg assembly.
  3. Remove the Lower Unit: Carefully lower the gearcase away from the engine. The driveshaft will slide out.
  4. Disassemble the Water Pump: Unscrew the bolts on the top of the water pump housing and lift it off to expose the impeller and wear plate.
  5. Inspect and Clean: Take note of the old parts' orientation before removing them. Clean any old gasket material or debris from the housing surfaces.
  6. Install New Components: Lightly grease the new impeller and install it into the housing cup, turning the driveshaft clockwise to bend the vanes correctly. Place the new gaskets and wear plate.
  7. Reassemble the Pump: Secure the housing with the new screws. Install the new drive key.
  8. Reinstall the Lower Unit: Guide the driveshaft back into the splines of the crankshaft, ensuring the water tube aligns correctly. Bolt the lower unit back into place.

Troubleshooting & FAQ

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

A: This kit fits a wide range of Johnson/Evinrude 4, 5, 6, and 8 HP 2-stroke outboards from 1980 to 2005. Check the "Compatible Engine Models" table to verify your HP and year range. Cross-reference the OEM part number stamped on your old water pump housing or impeller with the numbers listed in our cross-reference table.

Q: I saw a review mentioning the key size was wrong. Is this a common issue?

A: While the kit is designed for broad compatibility, slight variations can exist across decades of engine production. We recommend comparing the new drive key and other components to your original parts before installation. If a part does not match, please contact us before proceeding.

Q: What are the signs that my water pump impeller is failing and needs replacement?

A: A weak or inconsistent water stream from the "telltale" outlet is the most common sign. Other indicators include the engine overheating alarm sounding or the engine running hotter than usual. It is recommended to replace the impeller every 1-3 years depending on use (e.g., saltwater vs. freshwater, hours of operation).

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.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.

Quality product
Color: Navy, Size: 6-Quart
I absolutely LOVE my Dutch oven! The reduced cooking time for certain cuts of meat for stews, pot roast, etc., is a definite game changer!! The meat comes out so juicy and tender. I made curry and did the "burning" of the curry and was hesitant because I didn't want the pot to be stained. There were no stains left at all. I've used it numerous times since purchasing and it still looks new. It's very durable and the color is beautiful. If you're looking for a functional, quality, and durable Dutch oven without breaking the bank, this is it! I highly recommend.

Nothing Exceptional but Gets the Job Done
Color: Blue, Size: 4.3-Quart, Color: Blue, Size: 4.3-Quart
I’ve owned this 4.5 Qt. Amazon Enameled Cast Iron Dutch Oven for almost two months and have used it three times to date. Upon arrival and at first glance, the gradient blue color is beautiful and super glossy; most importantly, the pot is heavy for its size - as it should be. It looks exactly like the product pictures, with a globular shape than square shape as others. Unfortunately, I also noticed that there was one pin hole and two tiny uneven protrusions on the enamel inside the pot. I own three other enameled cast iron cookware from two other brands (photos attached for size comparison) and performance wise, this cast iron by Amazon performs equally to them. The pot isn’t exceptional or special but it gets the job done. Other than the pin holes and protrusions, I have no complaints. This isn’t my first rodeo so when heating up the pot and while cooking, I have zero issues. I am starting the pan off at 4-Stars and will update my review as time progresses, or if I have any major issues with its durability or performance in subsequent months. For the amateur home cook, or for anyone who is new to cast iron cooking, below I’ve included tips that you may find useful while using this or any other enameled cast iron cookware. ================================ Regarding the 3 Photos and 1 video I've Attached: (Note: all photos were taken with an iPhone under kitchen lights during the evening. Photos have not been edited nor enhanced.) Photo 1: Size comparison of this Amazon Enameled Cast Iron Dutch Oven compared to three other enameled cast iron cookware that I own from two other brands. From left to right: 7 qt. Tramontina, 4.5 qt. Amazon, 3 qt. Lodge 4 qt. Tramontina. Photos 2 and 3: fresh produce shown next to 4.5qt Amazon Dutch Oven for color and size contrast. Video: 4.5 qt. Amazon Enameled Cast Iron Dutch Oven on gas stove over medium heat, with food cooking. ================================ TIPS THAT YOU MAY FIND USEFUL While Using your cast iron dutch oven: (Note: I included these similar tips in my review of a different enameled cast iron pot from a different brand. My tips can apply to all enameled cast iron cookware) 1. If you find that you have issues with food sticking, it could be that you are not heating up your cast iron pot properly to prevent undue hot spots. I heat my pot up gradually starting at low, then medium, then high heat. After my pot is very hot is when I add my fat/cooking oil. As the oil is heating up in the pot, I lift it and swirl the oil around to coat all sides of the pot that will come in contact with food. 2. Take into consideration the temperature of the items you are adding to your heated pot. As a general rule for cooking: when ever possible, ensure that the items you are adding to a hot pot are at room temperature, rather than ice cold from the fridge; this will assist with even cooking. 3. Also, get comfortable with adjusting your heat by lowering and raising it based on what you’ve added to the pot. In general, you will need more heat at the beginning of the cooking process, and less heat towards the end. If you cook by recipe, I highly recommend that you read all the steps ahead before starting, so that you become familiarized with all the procedures, allowing you to maneuver accordingly when you start cooking. 4. At the exception of searing meat to achieve a brown crust, deep frying, or when caramelizing onions, you should be stirring your pot (I recommend using a wooden spoon) every few minutes when cooking in cast iron that is placed over high heat. If you are braising on the stove at low heat versus braising in the oven, the frequency of your stirring will need to be adjusted. No matter how you’re cooking though, a watchful eye on the pot plus stirring, should both be a habit not an afterthought. 5. For all cooking vessels in general but especially for cast iron: after cooking, allow your pot to cool down completely before cleaning. NEVER immerse a hot cast iron pot into cold water, nor pour cold dish water into hot pot. You risk not only being scald by dangerous steam, but you also risk weakening the enamel, therefore lessening the durability of your pots over time. 6. This cookware and others like it from Tramontina and Lodge are economical and if used correctly, will perform well for most cooking; if used correctly, they should also last for years. Nonetheless, if you can afford it, authentic enameled cast iron cookware made in France by Le Creuset is the best way to go. Le Creuset is the gold standard in cast iron cookware and their quality is second to none. I definitely recommend this Amazon dutch oven but if you can afford to splurge, Le Creuset's reputation is stellar. As a professional chef, I've used them in high end kitchens and their quality and performance is premier.

Nice BIG enameled cast iron dutch oven. like LeCreuset but costs less
Color: Blue, Size: 6-Quart
This is nice quality, similar to the far more costly French LeCreuset brand. I was surprised how big this model is, possibly too big for my small kitchen and limited storage space. I store it in the oven. It would be great for baking sourdough boule bread.
