Sierra NEW 18-2778 Water Inlet Hose Connector Replaces: Volvo Penta 832846 0810

Sierra Marine Water Inlet Hose Connection — Part Number 18-2778

Brand: Sierra | Condition: New Old Stock (NOS)

Genuine Sierra Marine part number 18-2778, the water inlet hose connection for Volvo Penta 270, 280 and 290 series sterndrives. It replaces Volvo Penta part number 832846 and the earlier 814356, and serves both gasoline and diesel installations. This is new old stock from long-term inventory, a genuine Sierra component carrying Sierra's Limited Lifetime Warranty.

This is the fitting where the cooling water hose connects to the drive's water intake passage — the entry point for every drop of raw water the engine uses to cool itself. It sits permanently submerged or splashed, in the one part of the drive where galvanic corrosion is most aggressive, and on a thirty- or forty-year-old 270/280/290 the original connection is frequently the component that has corroded, seized or cracked. When it fails the consequences are immediate: a raw-water leak at the transom, or worse, restricted cooling flow and an engine that overheats under load with no obvious cause.

Condition Details

New old stock. The connection is unused and has never been installed. As with all warehouse-stored inventory, the packaging may show shelf wear, dust, fading, price stickers, scuffs or minor crushing from stacking. The fitting itself is undamaged, with clean threads and sealing faces, no cracking, corrosion, galling or distortion from storage. Please review all photos, as what is pictured is what you will receive.

Please note on the part name: some retailers list this number as a thermostat housing. That appears to be a cataloguing error — Sierra's own description and the Volvo Penta application both identify it as the water inlet hose connection on the drive, not a thermostat housing. If you are shopping for a Volvo Penta thermostat housing, this is not that part, and we would rather tell you now than process a return.

Features

• Sierra Marine quality, engineered to meet or exceed the original Volvo Penta specification — Sierra has supplied marine replacement parts for over fifty years
• Sierra Limited Lifetime Warranty against defects in materials and workmanship, which is more coverage than an original Volvo Penta part carries
• Correct thread and sealing geometry for the 270/280/290 drive water intake passage
• New, uncorroded fitting to replace a component that lives permanently in raw water where galvanic corrosion is most aggressive
• Restores full cooling water flow — a restricted or corroded inlet connection is a classic cause of an overheat under load with no obvious culprit
• Stops the raw-water leak at the transom that a cracked or seized connection produces
• Serves both gasoline and diesel Volvo Penta installations
• Direct fit, no modification required

Application

Fits Volvo Penta sterndrives:

• 270 series
• 280 series
• 290 series

Catalogued for both gasoline and diesel Volvo Penta engines using these drives, under Volvo Penta part numbers 832846 and the earlier 814356.

The Volvo Penta 270, 280 and 290 drives had a long production run with several revisions, so buyers should confirm 18-2778, Volvo Penta 832846 or 814356 against the exploded cooling system or drive diagram for their specific drive and year before ordering. If you send us your drive model and serial number we will check it against the parts catalogue for you.

Why Choose Sierra?

Sierra Marine has produced marine engine and drive replacement parts for over fifty years, engineered to meet or exceed the specifications of the original engine manufacturers, and supplies both the aftermarket and OEM channels. Sierra's catalogue is one of the most comprehensive and best cross-referenced in the marine industry, and Sierra parts are backed by a Limited Lifetime Warranty. On a raw-water fitting for a drive that has been out of production for decades, Sierra is frequently the practical alternative to a Volvo Penta dealer price — and the lifetime warranty is worth having on a part that lives in salt water.
