A watercraft includes a deck and a hull having a transom, right and left side portions a tunnel, and a bottom portion. An air intake system disposed in the engine compartment and fluidly communicating with an engine includes an air compressor and an intercooler. The intercooler includes a housing having a lower surface extending generally along the bottom hull portion, an upper surface extending thereabove, an intercooler air inlet, an intercooler air outlet spaced from the intercooler air inlet at least in a direction parallel to the lower surface, a water inlet, and a water outlet. An intercooler core enclosed within the housing defines at least one air channel fluidly communicating with the intercooler air inlet and the intercooler air outlet. At least one water channel fluidly communicating with the water inlet and outlet is diathermally connected with the at least one air channel for cooling air flowing therein.

Intercooler for a watercraft

A sealing unit longitudinally comprises first and second sealing sub-units disposed around first and second portions of a driveshaft of a marine propulsion system of a watercraft. The first sealing sub-unit is sealingly connected to a front wall of the hull and the engine casing. The second sealing sub-unit is sealingly connected to the driveshaft and a crankshaft. The second sealing sub-unit is disposed at least partially inside the first sealing sub-unit. An inside of the first sealing sub-unit is in fluid communication with a water intake ramp. An inside of the second sealing sub-unit is in fluid communication with an interior of an engine. The first sealing sub-unit prevents fluid communication between the water intake ramp and a portion of an inside of the hull. The second sealing sub-unit prevents fluid communication between the engine, the inside of the hull, and the water intake ramp.
