I've read posts previously about replacing with stock automotive heater cores. Which one do I need? Can I pick it up from local GM dealer? Can I replace with a bigger (stronger) model?

I just replaced a 2 vent heater core on a buddies 05' PS 190. If this is what you got I can help out with some measurements but don't know of a cross reference. Would have posted a few more pics, but the work IPad limits me to one:mad: BTW, I replaced the bad core with a replacement from Discount Inboard Marine.

Two inches wide is the max as the core is cradled inside the heater box.

The heater box. Notice the tabs towards the rear. Hope this helps.
