Looking at a pressure gauge to diagnose this is almost useless because the gauge won't show pressure until there is resistance in the oil system. I would remove the coil wire from the distributor so the engine won't fire and then take the new oil filter off. Next crank the engine until you either see oil coming out of the remote filter bracket, or confirm that there is no oil flow and go from there.
I'm betting you do have oil flow which means you have a filter problem.
I'm a big fan of not over complicating boat repairs. Since the engine ran fine warming it up to change the oil, I'm thinking the problem is something filter related.....wrong filter, bad filter, etc. And, yes Virginia, there are bad filters. I've had more than one from Fram, Purolator, Delco and Motorcraft. They either wouldn't hold pressure (bad check valve) or wouldn't pass oil, like this post (bad by pass valve).
Good luck..........
