Description:
PP-817577-T Mercruiser Dual Cooler
This Seakamp Dual Cooler is a marine-grade replacement designed for Mercruiser marine petrol stern drives and inboard engines. The unit has a 3" Dia core.
This dual-cooler assembly combines two cooling functions in a single unit — typically engine oil and either transmission oil or fuel — with shared raw-water flow through a common shell. It is a space-efficient solution for engines with tight installations where separate single-purpose coolers would not fit.
Because a dual cooler manages two heat loads in one shell, both oil circuits depend on a common raw-water flow. Internal corrosion, scale or tube blockage compromises both systems simultaneously, so a like-for-like replacement on schedule protects every connected component at once.
Manufactured to match OEM dimensions, port orientation and mounting geometry, the 817577-T is a true direct-fit replacement for the original Mercruiser component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing.
