Troubleshooting & FAQ

Q: How do I confirm this kit fits my engine?
A: This kit is designed for most Johnson/Evinrude 85-300 HP V4, V6, and V8 outboards manufactured between 1979 and 2006. To ensure a correct fit, please carefully review the "Compatible Engine Models" table above and cross-reference your OEM part number (5001594). Note: This kit is not compatible with SL models.

Q: What are the signs my water pump is failing and needs replacement?
A: Common signs of a failing water pump include the engine overheating, a weak or inconsistent stream of water from the "tell-tale" outlet, or finding cracked/missing vanes on the old impeller during a physical inspection.

Q: How often should I replace my water pump impeller?
A: For optimal engine protection, we recommend inspecting the water pump and impeller annually and planning a full replacement every 1-2 years. If you operate primarily in saltwater or areas with high levels of sand or silt, more frequent replacement may be necessary.

Batana Oil for Stronger, Fuller Hair
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
I’ve been using this Batana Oil for a few weeks now, and I’m genuinely impressed with the results. From the very first use, my hair felt softer, more nourished, and noticeably healthier. The texture of the oil is rich but not overly heavy, which makes it easy to apply without weighing my hair down. What I love most is how it helps with dryness and frizz. My ends look less damaged, and my hair has a natural shine that I didn’t have before. I’ve also noticed less breakage when brushing, which is a huge plus. It feels like my hair is getting stronger over time. Another great thing is that a little goes a long way, so the jar lasts longer than expected. I like to use it as a scalp treatment and also as a leave-in on my ends, and it works perfectly both ways. If you’re looking for something to improve the overall health, thickness, and appearance of your hair, this Batana Oil is definitely worth trying. It gives that “salon-quality” feel right at home.

I have been using this batana oil in my hair and I really liked it. Leaves hair soft, with more shine and a healthier appearance. It feels nutritious without the need to use large amounts. It also helps control frizz and leaves the hair manageable. With constant use I have noticed that my hair looks stronger and more hydrated. Very good value for money.

Hair Growth Game Changer
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1), Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
Game-Changer for Hair Growth & Thickness I am seriously impressed with this 100% raw organic Batana oil. I’ve tried so many hair growth products, and this is one of the few that actually delivers real results. Within just a couple of weeks, I noticed my hair feeling softer, stronger, and way more hydrated. The biggest difference for me has been in thickness—my hair looks fuller, and I’m seeing new growth, especially around my hairline. It also adds a really healthy shine without making my hair feel greasy or weighed down. I love that it’s all-natural and unprocessed—you can tell it’s the real deal. A little goes a long way, so the jar will last you a while. I use it a few times a week as a scalp treatment and even on my ends to prevent dryness. If you’re struggling with thinning, breakage, or just want healthier, longer hair, I highly recommend giving this a try. Definitely a staple in my routine now!

This product is helping my afro hair truly thrive!
Scent: Bright Coffee, Size: 2 Fl Oz (Pack of 1)
I've used this product for 1 month so far. Applying to my scalp, hair and the ends of hair approx 1-2 times per week. These are my benefits on my long afro hair: - First off, my scalp doesn't particularly like oil on it, it would trigger itching, dandruff, etc., but it certainly loves this stuff. - bald spots started growing back in. - drastic reduction in hair shed. - For a long while, I had difficulty retaining hair moisture. My hair is FINALLY getting the nourishment and moisture it needs and deserves. - hair is noticeably softer and even more manageable. - I detangled my entire head within 15 minutes the other day which is a first for me. - Hair is thickening. Which in my opinion is because my hair is shedding less. Like my braids appear half an inch thicker than they were. - Scalp stopped itching. - Dandruff stopped. As far as the scent goes, it smells soo good to me. i read authentic batana oil is supposed to smell like burnt coffee. Maybe it's just me but it smells like caramelized honey. All in all I'm soo happy i was guided to batana oil because it has done wonders for me in such a short period of time. Very happy with my purchase and would recommend.

Thicker & Healthier Hair
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
I’ve been using this Batana oil for a few weeks and I can already see a difference in my hair. My hair feels softer, thicker, and looks much healthier. The scalp oil keeps my scalp moisturized without feeling too greasy, and the natural formula gives me confidence that I’m using a quality product. I also noticed less hair shedding and better shine after regular use. The scent is natural and the mask is easy to apply. Great for both men and women who want stronger, fuller-looking hair.
