You need to be more specific. Some of them, like he LT-1 for example, have a hole drilled in them for a small amount of constant bypass. Literally it is a predetermined hole size from the engine builder and they drill it with a drill bit. I bought mine from skidim and had to de-burr it before install.

Mine is a 1987 ProStar 351 Ford engine. Had issues over the weekend and used a automotive style 160 stat temp seemed to run 172-ish. would cycle but didn't know if it would be a problem long term??

Stick with the specific thermostat for your boat, there is a difference.

most marine t-stats drilled to allow bypass of some water when closed.
