You know with how close my engine is to the stringer I am not sure I have room for side ports. I am going to get the boat out of the garage today and get her ready for the water. That way I can look and see what room I have. But currently to change my oil filter I have to take off the P-clamp that holds the wiring harness and 2 of the plug wires to squeeze my hand in a narrow gap to get to the filter. Once I have it loose I have to have somone on the other side of the block ready to grab the filter as there is NO way it can come out the port side but there is plenty of room on the starboard side for it to clear.
