Outboard overheating and a loose hatch are two very different problems, but both send boat owners hunting for marine replacement parts. The right pick depends on what is actually broken: if your motor is running hot, you likely need the water pump kit; if your hatch handle is failing or water is seeping through, you need hatch hardware. These two parts address separate systems and are priced accordingly.
Quick verdict
If your Johnson, Evinrude, or OMC outboard in the 20 to 35 HP range needs cooling-system maintenance, the Water Pump Kit at $19.99 is the part to get. If your boat was built between 1987 and 1993 and the hatch handle or seals are failing, the Hatch Replacement Parts at $62.99 is the better fit. Neither product can fix the other's job, so your decision is really about identifying the failing system.

Where each product wins
Water Pump Kit wins when: your outboard is in the 20 to 35 HP range, you see signs of a failing impeller, and you want the full set of wear items in one package. The kit matches multiple OEM part numbers, including 393630, 0393630, 395289, 393632, and 328755.
Hatch Replacement Parts wins when: your boat is from the 1987 to 1993 model years, the hatch handle is damaged, or the O-rings are old and leaking. The black hardware and included screws give you what you need for this specific repair.
Product notes
Water Pump Kit for Johnson Evinrude OMC 20 25 30 35 HP Outboard Boat Motor Parts
This water pump service kit is built for cross-flow outboards with thru-prop exhaust and a one-piece gear case, which covers a range of Johnson, Evinrude, and OMC motors from 20 HP to 35 HP. It bundles the neoprene impeller, key, gaskets, wear plate, pump cup, pump housing, O-rings, and installation bolts, so you do not have to source separate wear parts. The listed replacement numbers cover 393630, 0393630, 395289, 393632, and 328755. Choose this kit if your motor is overheating or your impeller has not been changed in a while. The limitation is that it is not a universal engine part: the kit targets specific cross-flow engine builds and a defined horsepower range, so you need to confirm your engine falls within the described groups before ordering.
Hatch Replacement Parts for 1987-1993 Model Compatible With Boating
This hatch replacement package is aimed at boats built between 1987 and 1993, with a black finish and a compact footprint of 13 by 9.2 by 1.3 inches. The kit includes the handle with post, O-rings, and screws, which covers the main wearable pieces in a hatch latch system. It weighs about 1 lb, so it is a lightweight part to keep aboard. Choose this when your existing hatch handle is stripped or cracking, or when the O-rings no longer keep water out. The trade-off is the narrow scope: it is designed specifically for 1987-1993 models and for hatch hardware only, so it will not address unrelated deck fitting issues or any engine cooling problem.
Final choice by use case
- For a 20-35 HP Johnson, Evinrude, or OMC outboard that runs hot: go with the Water Pump Kit.
- For a 1987-1993 boat with a broken hatch handle or leaking hatch seals: go with the Hatch Replacement Parts.
- If you need to address both repairs, the lower-priced water pump kit is the natural starting point because it is a service item, but the hatch kit is a separate purchase for its own job.
