How do I know if this exhaust hose fits my engine?

This hose is made for MerCruiser stern drive models 470/485, 185, 205, 898, 228, and 260 from approximately 1976–1987. To ensure a perfect match, please cross-reference your engine model and year with the detailed compatibility table on this page.

What are the signs of a failing exhaust tube hose?

Common signs of failure include visible cracks, bulges, brittleness, or softening of the rubber. You might also notice water leaking into the engine bay, an increase in exhaust noise, or exhaust fumes in the bilge area.

Do I need to buy anything else for installation?

Yes, this hose requires four 5-inch hose clamps to ensure a secure, leak-proof installation. These are not included with the hose and must be purchased separately.
