As you will be aware OMC no longer exists however we can supply replacement heat exchangers and engine or transmission oil coolers for most OMC engines, if you have a engine serial number we can reference this with our database or if you have the part number that is even better as a last option send us pictures of the failed original . We deal direct with the factory producing original equipment and as such can offer you low prices. We look forward to being of assistance, email or call!
