Installation Guide

  1. Disconnect Power: Disconnect the battery and spark plug wires to prevent accidental starting.
  2. Access Lower Unit: Drain the gearcase oil and detach the lower unit (gearcase) from the outboard's midsection.
  3. Remove Old Pump: Locate the water pump assembly on top of the lower unit. Unbolt and remove the old pump housing and components.
  4. Clean Surfaces: Thoroughly clean the mounting surfaces, removing any old gasket material or corrosion.
  5. Install New Components: Assemble the new kit components in reverse order, starting with the wear plate, gaskets, and pump cup.
  6. Install Impeller: Slide the new impeller onto the driveshaft, ensuring the key is in place and rotating the shaft clockwise to seat the fins correctly inside the housing.
  7. Secure Housing: Install the new housing and tighten the bolts to the manufacturer's recommended torque specifications.
  8. Reassemble & Test: Reattach the lower unit, refill the gearcase oil, and reconnect the battery/spark plugs. Test the engine in water to verify proper water output from the tell-tale port.

Troubleshooting & FAQ

How do I confirm this fits my engine?
Start by checking your engine's model, horsepower, and year against the "Compatible Engine Models" table. Be sure to check the notes, as some models have exceptions. Cross-reference the part number with your existing part or service manual. Pay close attention to the exclusion note: this kit does not fit Johnson-rebranded Suzuki engines (2002-2007) or Bombardier 4-strokes.
What are the signs my impeller needs replacement?
Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, or a noticeable decrease in cooling performance. It is recommended to replace the impeller every 1-2 years or every 100-200 hours of use, regardless of visible wear.
Does this kit fit 4-stroke models?
Yes, this kit is compatible with specific Johnson/Evinrude 9.9 HP and 15 HP 4-stroke outboard models from 1995 to 2001. It is not compatible with later Bombardier-branded 4-strokes.

Great Product for the Price! Love!
Size: Medium, Color: Dark Grey
Unless you have a very strange out of proportioned body, this will probably work out great for you! Even if you are a little heavy on bottom or up top---you can probably upsize and get a good fit. I was amazed after purchasing two of these suits, one in black with a peak lapel for my husband, and a grey shawl collar for my son---they are plenty long in the pants and my boys are a little above average height at 6' and 6' 1". The material is great and they are absolutely fine and include a bow tie and pocket square as well. Unless you are James Bond and are gonna wear this suit on the regular, I think it will be perfect for most men for several occasions, weddings, prom, or any super special occasion or event where you need to look great. I will say that even my son at 6' 1" needed the pants shortened, and I am glad because I feared they would be too short. For some reason, my husband's were perfect on the pant length. I am glad that I bought these and took the chance. I paired them with patent black shoes that I also found on Amazon, and my boys looked fantastic! For reference my husband is a 38 waist and 32 length pant and a 46 reg jacket, muscular build and I ordered him the XL slim fit, when he normally wears a L. My son is a 32 waist and 33 length pant and 38 reg jacket, with a very slim muscular build. I ordered him the slim fit Medium, and he typically wears a M. These sleeves are supposed to be a little bit "short" so that the cuff of your shirt is clearly visible, fyi. Both fit and no returns, but my son's vest was a little large on him. My son is super fit, lean, and my husband has a (gorgeous) 😉 dad bod with a dad belly but not a pot belly. His vest was perfect. The vests are adjustable in the back. Be aware that the pants do not have the satin stripe down the side if that is what you are looking for. My boys have tuxedos with the striped pants as well and they were from a department store and are wonderful, BUT out of the bag? for this price? and one minor adjustment on the pants?... I am still amazed these worked out so well! I almost feel sorry for the suckers who pay too much, because you don't need to! Lastly, they were both folded compactly and nicely in packages that had not been previously opened. They needed a minor steam but were not incredibly wrinkled. They shipped quickly and were slim fit but not a SUPER ridiculous slim fit. The fabric weight is on the thinner side on the pants, but still all a go and wins for us. Who knew? Tuxedos from Amazon! Yes!

Perfect for Formal Events – Looked Amazing at a Mardi Gras Ball
Size: Medium, Color: Black
My husband wore this 3-piece suit to a Mardi Gras ball and it was absolutely perfect. The fit was true to size, and the vest really elevated the overall look. The material felt high quality for the price—comfortable, breathable, and not stiff at all, even after hours of wearing it. He received multiple compliments throughout the night, and the suit photographed beautifully under ballroom lighting. It arrived well packaged and needed minimal steaming before wearing. Overall, we were very impressed with the style, quality, and value. We would definitely purchase again for future formal events.

Good Quality overall. Pants need work.
Size: 4X-Large, Color: Black
I'm 6'0. 305 lbs and have a beer belly. The 4xl jacket fit like a glove. The vest on the other hand is hard to button and I can't use it. The pants, as expected are a few inches too long and a bit baggy from the knee to the butt and I will have to have them altered. I will say the pants cannot be pulled up too far as the crotch area is very shallow. I wish there were just a bit more room there to pull the pants over my belly. The overall quality is 3.8 out of 5.
