A marine drive assembly for propelling a marine vessel in a body of water, the marine drive assembly comprising:

• a drive unit having a propulsor for generating a thrust force in the body of water;
• a mounting bracket for mounting the drive unit to the marine vessel, the mounting bracket having an exterior facing outside the marine vessel and an interior facing inside the marine vessel;
• and
• a heat exchanger configured to exchange heat between water from the body of water and a cooling fluid for cooling a component of the marine drive assembly, wherein the heat exchanger is coupled to the exterior of the mounting bracket;
• and
• a cooling water pump that pumps the water from the body of water to the heat exchanger wherein the cooling water pump is coupled to the mounting bracket outside the marine vessel.
