Along with aftermarket suppliers like Summit and Jegs, there are many applications that used remote filters, my Southwind RV with BBC has a dual oil filter/ cooler set up. You might be able to find a stock application in the boneyard. Still another option is to find a boat being parted out that might have all the brackets and such. BTW, beautiful Marauder, I saw it with the trailer, but your 16 was already in the water.
