It is the highest-specification kit in the 21951340–21951362 impeller series, designed for larger raw water pump assemblies in the applicable Volvo Penta engine range. The kit includes a precision-molded flexible rubber impeller along with the pump cover gasket, O-ring\/sealing components, and installation lubricant needed for a complete pump service.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Part number 21951362 is a distinct OEM reference from the related impeller kits in this series: \u003ca href=\"\/products\/8131482452004\"\u003e21951346\u003c\/a\u003e, \u003ca href=\"\/products\/8131482484772\"\u003e21951348\u003c\/a\u003e, \u003ca href=\"\/products\/8131482517540\"\u003e21951352\u003c\/a\u003e, and \u003ca href=\"\/products\/8131482550308\"\u003e21951360\u003c\/a\u003e.

In saltwater or high-use applications, annual replacement is strongly recommended regardless of hours. Do not wait for overheating symptoms — a degraded impeller can shed blade fragments that travel downstream and damage heat exchangers or thermostats.\u003c\/p\u003e\n\n\u003ch2\u003eWhen to Replace\u003c\/h2\u003e\n\u003cp\u003eReplace this impeller kit when the existing impeller shows cracked, missing, or hardened vanes, reduced cooling water flow at the exhaust, or any engine overheating. Also replace after extended storage where the impeller may have taken a permanent set. Replace the gasket, O-ring, and apply fresh lubricant at the same time — all are included in this kit.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eApply the included lubricant to the impeller before insertion — dry installation can damage the blades immediately on first start. Install with the correct vane rotation direction for the pump. Replace all gaskets and O-rings included in the kit. Inspect the pump housing bore for scoring or wear. After reassembly, check the cooling circuit for any broken vane debris before returning the engine to service.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I know if 21951362 is the right kit for my engine?\u003c\/strong\u003e\u003cbr\u003e\nA: Look up your engine serial number in the Volvo Penta parts system and match the raw water pump diagram. The 21951362 is the highest-specification kit in this series and applies to larger pump assemblies — if your diagram calls for a different number in the 2195134x–2195136x range, order that kit instead.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What happens if a blade breaks off?\u003c\/strong\u003e\u003cbr\u003e\nA: Broken impeller blades travel through the cooling circuit and can lodge in heat exchangers, thermostats, or other restrictions. If you find a damaged impeller with missing blades, flush the cooling circuit and inspect downstream components before returning the engine to service.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the old gasket if it looks intact?\u003c\/strong\u003e\u003cbr\u003e\nA: Not recommended. Gaskets compress during initial installation and rarely seal correctly when reused. This kit includes a replacement gasket for that reason.\u003c\/p\u003e\n\n\u003ch2\u003eRelated Parts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/8131482550308\"\u003eVolvo Penta Impeller Kit 21951360\u003c\/a\u003e – next kit down in the series (D4\/D6\/V6\/V8)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/8131482517540\"\u003eVolvo Penta Impeller Kit 21951352\u003c\/a\u003e – related OEM impeller kit for D4\/D6\/IPS\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/8131482484772\"\u003eVolvo Penta Impeller Kit 21951348\u003c\/a\u003e – related OEM impeller kit for D4\/D6\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/8131482452004\"\u003eVolvo Penta Impeller Kit 21951346\u003c\/a\u003e – related OEM impeller kit for D4\/D6\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/8131482386468\"\u003eVolvo Penta Seawater Pump Cover Screw Kit 21951334\u003c\/a\u003e – pump cover screws for D3\/D4\/D6\/KAD\/TAMD\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/8266781753380\"\u003eVolvo Penta Seawater Pump Wear Kit 21951374\u003c\/a\u003e – wear components for the seawater pump family\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThe 21951362 is the top-of-range kit in this impeller series and is typically required for the largest raw water pump assemblies in the Volvo Penta lineup.
