When a marine replacement parts order starts with a generator exhaust elbow, you're often juggling two problems at once: the damaged exhaust riser and the routine service parts that are due at the same time. If you're working with a Westerbeke generator, this new 13-piece lot bundles the exhaust elbow with the kind of OEM service parts you'd want on hand.
Quick verdict
The NEW Westerbeke Marine Generator Exhaust Elbow lot is a single, USD 500.00 package that pairs the red-painted flanged exhaust riser/mixing elbow with an oil filter, air filter element, drive belt, exhaust gasket, brass plug, brass elbow fitting, and valve stem seals. For a boat owner or marine mechanic planning a Westerbeke exhaust service plus routine maintenance, it covers the job in one purchase. The catch is that it's one specific parts assortment, not a universal kit, so the 037533 exhaust elbow and the included part numbers need to match your generator before you commit.
What stands out from the listed details
The lot is centered on the 037533 exhaust elbow and includes a long list of supporting OEM service parts: 035828 oil filter, 24-28802 air filter element, 042790 drive belt, 036425 exhaust gasket, 036849 3/4 NPT brass plug, 036614 brass elbow fitting, and valve stem seals (040238 qty 4, 033660). All parts are brand-new in original factory packaging. The 13-unit quantity is one of the useful details here-it's less of a single-part emergency buy and more of a maintenance-ready parts lot.
Who it suits
This suits someone who already knows which Westerbeke exhaust elbow and service parts their generator needs and wants to handle the exhaust and filter/belt/gasket work at the same time. It also makes sense for a marine mechanic who services Westerbeke generators regularly and can use the filters, belt, and seals as consumable spares. If you're at the early research stage and don't yet know your generator's part numbers, this lot is not the place to start.
Meaningful trade-offs
You're making one buying decision for many part numbers at once. That's convenient for a planned service, but it also means you're paying USD 500.00 for the whole assortment even if you only need the exhaust elbow. Because the included parts are clearly itemized, you can compare the 037533 exhaust elbow and the filter, belt, and seal part numbers with the service parts for your specific generator before purchasing. This is a defined lot, not a universal kit, so the fit comes down to those listed part numbers.
Bottom line
If the part numbers line up with your Westerbeke generator, the NEW Westerbeke Marine Generator Exhaust Elbow- Lot OEM Filters Belt Gasket Seals is a solid way to consolidate an exhaust repair and routine maintenance into one USD 500.00 purchase. If you're unsure about compatibility or only need the elbow itself, keep looking for a single part that directly answers that one need.
NEW Westerbeke Marine Generator Exhaust Elbow- Lot OEM Filters Belt Gasket Seals

The headline item is the 037533 exhaust riser/mixing elbow, and the lot also includes the 035828 oil filter, 24-28802 air filter element, 042790 drive belt, 036425 exhaust gasket, 036849 3/4 NPT brass plug, 036614 brass elbow fitting, and valve stem seals (040238 qty 4, 033660). At USD 500.00, this new, original-factory-packaged 13-piece lot is an efficient choice when the listed part numbers match your generator's needs. Its limitation is the same as its strength: it's a fixed bundle, so you can't trim away the parts you don't need.
