It's a self-priming flexible impeller pump, and it's beltless, so it turns right off the front pulley and gets sea water moving the moment you crank. When the old pump weeps or the impeller wears out, this is the direct-fit replacement.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you run a Volvo Penta 8.1L V8, the raw water pump is the part that keeps your whole cooling loop honest. This Albin pump mounts right on the crankshaft pulley and starts pulling sea water through the system the moment the engine turns over. There's no separate accessory belt to tension and none to throw. When the old crank pump starts weeping at the shaft seal, or the impeller finally gives up and your temps start climbing, this is the beltless replacement that gets you back on the water.\u003c\/p\u003e\n\u003cp\u003eIt's a self-priming flexible impeller pump, what most techs just call an FIP. The rubber impeller does the real work, flexing as the pulley spins and sweeping water through the housing on every rotation. Because it's crank-driven and beltless, it turns at engine speed and gets flow going right away, which matters on a big-block gas engine that dumps a lot of heat under load. The gold and silver casting is the Albin build you'll recognize the second you have it in your hands.\u003c\/p\u003e\n\u003cp\u003eThis one is set up for the 8.1L Volvo Penta gas engines, the 496-cube big blocks you'll find in a lot of express cruisers and larger sportboats from the mid-2000s on. If your engine uses the crank shaft pulley-mounted pump rather than a belt-driven accessory pump, this is your part. Check your mounting before you order. Some 8.1L installs run the pump off the front pulley and some are set up differently, so match the crank-mounted style to what's actually bolted to your engine right now.\u003c\/p\u003e\n\u003cp\u003eRaw water pumps are wear items, plain and simple. The impeller lives in salt water, it takes abuse from sand and shell grit, and it runs dry for a couple seconds on every single start until prime catches. Vanes crack. They take a set. They shed bits of rubber downstream into the cooling passages where you really don't want them. If you're seeing higher running temps, a weak telltale, or you've pulled the cover and found a chewed-up impeller, odds are the pump itself is tired too. The shaft seal and the bearing wear right along with the impeller, and once a housing wears oval, a fresh impeller won't seal against it. That's the point where you stop chasing overheats and just put a whole new pump on.\u003c\/p\u003e\n\u003cp\u003eSwapping a crank-mounted pump is a bit more involved than a belt-driven one, because it sits up on the front of the engine, but it's straightforward work with the boat on the hard or the intake seacock closed. Close that seacock first. Always. After that it's hoses, the pulley hardware, and the mounting. Take the opportunity to look over your hoses and clamps while you're in there, because a brand-new pump pushing through a soft fifteen-year-old hose is a false economy. Prime the system, open the seacock back up, and confirm you've got strong telltale flow before you leave the slip.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about raw water flow: it feeds everything downstream. The pump moves sea water through your heat exchanger, your exhaust risers, and your manifolds, and all of those cost a whole lot more to replace than a pump does. Keep a spare impeller aboard and pull the cover to check it every season. Run the engine, watch the telltale, and listen to the exhaust note. A pump that's moving water the way it should keeps the expensive parts of your cooling system alive through a long, hot day offshore.\u003c\/p\u003e\n\u003cp\u003eGet this one mounted right and your 8.1L stays cool when you're loaded down and running hard. And if you're not certain it's the exact pump for your setup, call us with your Volvo Penta model and serial number and we'll confirm the fitment before you spend a dime. We'd rather get you the right part the first time.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSelf-priming flexible impeller pump (FIP) pulls water the moment the engine cranks, so prime catches fast on startup\u003c\/li\u003e\n  \u003cli\u003eCrank shaft pulley mounted and beltless, so there's no accessory belt to tension, slip, or throw\u003c\/li\u003e\n  \u003cli\u003eTurns at engine speed for strong raw water flow when the 8.1L is working hardest under load\u003c\/li\u003e\n  \u003cli\u003eBuilt specifically for 8.1L V8 Volvo Penta gas engines that use the front crank-mounted pump\u003c\/li\u003e\n  \u003cli\u003eGold and silver Albin casting, the direct-fit replacement when the old crank pump weeps or the impeller wears out\u003c\/li\u003e\n  \u003cli\u003eComplete pump assembly with housing, shaft, and seal, so a worn housing gets fixed too, not just the impeller\u003c\/li\u003e\n  \u003cli\u003eRaw sea water cooling design, the front-line part that protects your heat exchanger, risers, and manifolds\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Albin Group reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat engines does this Albin pump fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's built for 8.1L V8 Volvo Penta gas engines that use the crankshaft pulley-mounted raw water pump.
