Just boat the boat. Noticed water in power steering reservoir. Just going to drain and replace oil cooler as that seems to be the usual culprit for this. Anyone have the correct part number? Is it 983849? Thank you. Any tips or suggestions on this replacement? I don't know a whole lot about OMC's, but this shouldn't be that big of a deal to swap. Thank you.

Ayuh,.... Why not pull it, pressure test it, 'n solder the leak closed,...

Not alota differences in P/S coolers,...

3/8" oil lines, 'n I believe 1" water lines,...

any radiator shop will charge $35 to repair by doing exactly what Bondo stated.

your oil cooler is nothing more than a bundle of 1/4" copper tubing within a 2" copper tube with some stamped copper tube sheets....and a bit of soldering or brazing from the factory.
