Installation Guide

  1. Safety First: Disconnect the boat's battery before beginning any work.
  2. Drain Lubricant: Place a drain pan under the lower unit and remove the drain/fill screws to empty the gearcase lubricant.
  3. Remove Lower Unit: Unbolt and carefully detach the lower unit (gearcase) from the engine's upper assembly.
  4. Access Pump: Unscrew the bolts securing the water pump housing to the lower unit.
  5. Remove Old Components: Lift off the old housing. Remove the impeller, wear plate, and gaskets. Note their orientation.
  6. Clean Surfaces: Thoroughly clean the mounting surface on the gearcase, removing any old gasket material or debris.
  7. Install New Kit: Place the new gasket and wear plate. Slide the new impeller onto the drive shaft (turn clockwise) and install the drive key.
  8. Reassemble Pump: Fit the new housing over the impeller and bolt it down to the specified torque.
  9. Reattach Lower Unit: Guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube align correctly. Secure with bolts.
  10. Refill Lubricant: Fill the gearcase with the recommended marine gear lubricant from the bottom hole until it emerges from the top hole. Re-install both screw seals.
  11. Test Operation: Reconnect the battery. Safely start the engine in water and confirm a steady stream of water from the "tell-tale" exhaust port.

Great design and size for an evening bag!
This PU leather bag is perfect for dressy occasions. I love the design and the size. The closure on the front is very unique. I don't need a purse like this often, but I like to have a few basic colors on hand for when I do need one. I didn’t have a gold bag so I ordered that color to add to my evening bag collection. I really am happy with this bag and have used it a couple of times already. This bag seems to be well made and durable. I haven't noticed any issues with it so far. I prefer the top handle but I like that a shoulder strap is included, although I haven't used it yet. The front closure is such a neat design. I really like the weave design of the rest of the bag too. The size is just right for what I like to carry in an evening bag. Some bags are too small and I can't even fit my phone in them. The size of this bag accommodates my phone, a small wallet, a small pack of tissues, and my lipstick. I think the price is good for the quality. I am very glad I ordered this bag. I recommend this bag as an affordable option for a nice quality evening bag. I don't yet know how well it will hold up over time, since I haven't had the opportunity to use it much yet. However, I don't anticipate having any problems. I will update this review if I obtain more insightful information in the future.

Elegant Evening Clutch That Looks Dressy but Still Practical
I bought this gold woven clutch for a wedding and wanted something that looked dressy but could still hold my essentials. I tested it the night before the event to make sure everything fit, and it worked out better than expected. The woven gold finish looks more refined in person than in photos. It catches light nicely without being overly shiny, so it pairs well with both simple dresses and more detailed outfits. The size is slim but long enough to fit my phone, cards, keys, and a small lipstick without forcing it closed. The PU leather feels smooth and structured, so the bag keeps its shape instead of collapsing when you set it down. The frame and closure feel secure — it snaps shut cleanly and didn’t pop open while I was moving around and greeting people. I carried it through a full evening — ceremony, dinner, and standing conversations — and it stayed comfortable in hand. It’s lightweight, which helps during longer events when you don’t want a heavy bag hanging from your wrist. If I had one small note, you’ll want to keep bulky items out since it’s designed to stay sleek. Overall, it’s a stylish, event-ready clutch that adds a polished touch without being flashy or impractical.

Sleek, modern, and surprisingly spacious
I’ve been looking for a statement piece to carry for a few upcoming spring weddings, and this bright gold clutch immediately stood out with its unique woven texture. The gold is vibrant and has a lovely shimmer that isn't too overpowering, making it feel sophisticated rather than flashy. I was pleased to find that the PU leather is quite soft to the touch, and the overall construction feels solid and well-crafted. The interior space is actually much better than most evening bags I’ve used in the past. It easily fits my smartphone and essentials with room to spare, so I’m not constantly struggling to close it. Since my niece often likes to play "dress up" with my accessories, I appreciate that the material feels durable enough to handle a bit of extra attention. It also comes with a detachable strap, which is great for when I want to switch from a classic clutch to a more relaxed shoulder bag. It’s a stylish, functional piece that adds the right amount of elegance to any formal look.

Elegant Woven Clutch with Versatile Styling Options
This woven clutch presents a refined look that works well for formal events and evening occasions. The textured surface catches light subtly, adding visual interest without appearing overly bold. The material feels smooth and structured, giving the bag a polished appearance that pairs easily with dresses and more understated outfits alike. The size is practical for essentials such as a phone, wallet, keys, and a few cosmetics, making it suitable for weddings, dinners, or parties. The interior space is used efficiently, and the clasp closure feels secure during use. The detachable shoulder strap adds flexibility, allowing it to be carried as a clutch or worn over the shoulder depending on the occasion and outfit. Design details and functionality are well balanced, making this clutch a reliable accessory for formal settings. It offers a thoughtful combination of style, capacity, and carrying options, fitting seamlessly into a variety of special-event wardrobes.

A Little Gold That Goes a Long Way
I carried this clutch to a wedding where my phone felt bigger than the dinner plate, and somehow everything fit. The woven finish looks classy without screaming for attention, and the gold tone works nicely with both bold and simple outfits. It feels light in hand but not flimsy, which is always a pleasant surprise. The size is just right for essentials like a phone, keys, and lipstick, though overpackers will need restraint. The closure stayed secure all night, even after some enthusiastic dancing. It is not meant for daily use, but for special events it does its job well. Stylish, practical, and easy to carry without stress.
