Changing motor over...both big block mercruisers. Old motor is a 1988 7.4L with the oil cooler on the lower side of block (rh lower if standing in front of it). New 502 Mag had (1990) oil cooler in back. I'm running my cooler the same way it was on the original motor. I'm looking for a part number for the water hose that goes from the thermostat housing down the front of the motor, along the lower side, and to the cooler ( I think it goes to the back of the cooler ). Then I need the hose that goes from the front of the cooler (I think) to the raw water pump. It sorta snakes around the front of the oil pan. Pleeeeeease...somebody's gotta know this set-up, and what the part numbers are. Thanks guys.

Try this cooler # 63832T Jim @ Mr C@@L 866-726-C@@L
good luck

Thanks..but I'm not looking for a new cooler. I need the hose part numbers for the original merc hoses.

Go to BAM Marine website and look up the pics and part #s

I'll hafta call them tomorrow...Thanks sir.

Try looking at the new and old design of the thermostat housing to see if that is what you are looking for,http://www.mercruiserparts.com/selec...?doc_nbr=19013
