• Part Number 99356a1 is the same as 99356A2 but with 1 inch water fittings.  If you need to order the 99365A1 please go here:  https://www.mrcool.us/99356a1-mercruiser-power-steering-cooler.html 

• You'll see this advertised by competitors with a full bundle which will cool but will also reduce your fluid velocity for the entire cooling system, which reduces it's overall efficiency.  For over 35 years the both Volvo and Mercruiser have opted for a sleeve bundle to reduce the back pressure and loss of fluid velocity to the rest of the cooling system.  This is the right part for you.
