Sorry to hear you had problems- I have seen 2 different filter adapters for remote filter setups.
On the normal automotive block mounted filter setup, there is an aluminum casting which is bolted onto the filter pad from underneath. This casting has a threaded nipple which the filter screws on to, and also has a filter bypass which bypasses the filter when it is clogged.
on the first type remote filter setup, an adapter screws on like an oil filter. this adapter has the 2 oil line connections to it. I would worry about this coming loose under severe use (boat).
The second type of adapter bolts to the filter pad in place of the factory filter/bypass assembly. It is possible these could come loose.
Another possible oil hose connection point is directly above the filter pad. I don't remember on small blocks, but on the big blocks there are 1 and sometimes 2 threaded holes which are normally plugged, and can be used for oil feed/return
Hope the motor isn't hurt, and good luck
