Hi all, I have the opportunity to pick up a Mark 15. It looks by seeing the pictures that it is the type that uses the Mercury pressure tank. Also , Where the fuel connector is suppose to be, It looks like it’s missing. That would be the hole in the cowl by the tiller. Can these be converted to a fuel pump like the Johnsons and Evinrudes? I’m not sure what ignition it has but I’m sure that is a whole nother chapter on its own. Thanks , Matt.
