Mercruiser BB Thermostat Housing conversion?
Motor: Mercruiser 330/454, raw-water cooled (standard cooling), TRS.
I'm converting from log-style manifolds to center rise. Now that I'll only be using two hoses per side (manifold/riser), my existing thermostat housing has four extra water outlets. Can I block-off the unused outlets or must I upgrade to the new-style thermostat housing?
Thanks in advance,

Block off the riser water ports and use bottom ports in manifolds for the water to exit. You use the boat in warm water, so I'd use riser gasket# 27-863726 (if your using Merc manifolds). Use 140 thermostat and drill 2 3/16 holes in thermostat flange.
