A weak pee stream, the engine running warmer than it should, or a bit of steam at idle usually means the impeller isn’t moving water the way it used to. This kit gives you everything to rebuild the pump the right way—impeller, gaskets, o-ring, plates, the key, and the hardware most folks drop in the grass at least once. It’s a small job that makes a big difference in how these small engines stay alive.\u003c\/p\u003e\n\u003chr data-start=\"643\" data-end=\"646\"\u003e\n\u003ch3 data-start=\"648\" data-end=\"666\"\u003eKey Features\u003c\/h3\u003e\n\u003cp data-start=\"667\" data-end=\"1130\"\u003e • \u003cstrong data-start=\"670\" data-end=\"687\"\u003eFull Pump Kit\u003c\/strong\u003e – Impeller, plates, gaskets, o-ring, key, and hardware included.\u003cbr data-start=\"752\" data-end=\"755\"\u003e • \u003cstrong data-start=\"758\" data-end=\"801\"\u003eMade for 3.3HP Mercury \u0026amp; Mariner Models\u003c\/strong\u003e – Fits the F-N-R versions of these portable outboards.\u003cbr data-start=\"856\" data-end=\"859\"\u003e • \u003cstrong data-start=\"862\" data-end=\"887\"\u003eRestores Cooling Flow\u003c\/strong\u003e – Helps bring back a strong telltale and steadier temps.\u003cbr data-start=\"944\" data-end=\"947\"\u003e • \u003cstrong data-start=\"950\" data-end=\"980\"\u003eFlexible Impeller Material\u003c\/strong\u003e – Works well across cold mornings and hot summer water.\u003cbr data-start=\"1036\" data-end=\"1039\"\u003e • \u003cstrong data-start=\"1042\" data-end=\"1063\"\u003eOEM-Tuned Fitment\u003c\/strong\u003e – Matches Mercury’s clearances so the pump builds proper pressure.\u003c\/p\u003e\n\u003chr data-start=\"1132\" data-end=\"1135\"\u003e\n\u003ch3 data-start=\"1137\" data-end=\"1170\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h3\u003e\n\u003cp data-start=\"1171\" data-end=\"1282\"\u003e • Mercury 3.3HP\u003cbr data-start=\"1187\" data-end=\"1190\"\u003e • Mariner 3.3HP\u003cbr data-start=\"1206\" data-end=\"1209\"\u003e • F–N–R small outboards\u003cbr data-start=\"1233\" data-end=\"1236\"\u003e • Dinghies, inflatables, tenders, jon boats\u003c\/p\u003e\n\u003chr data-start=\"1284\" data-end=\"1287\"\u003e\n\u003ch3 data-start=\"1289\" data-end=\"1327\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/h3\u003e\n\u003cp data-start=\"1328\" data-end=\"1698\"\u003eOnce you rebuild the pump on these little motors, you usually notice the improvement right away.
