warm vs cold riser gaskets

[wayne smith]

I have a warm manifold setup (water also goes to riser from thermostat housing)....

I just got new manifolds and risers.....they sent me cold manifold gaskets..large oval opening vs weep hole.......

can i use to cold gasket or exchange them for warm gaskets??

new ones on the way...butttttt
the dealer said that the cold gasket with the big holes will make the engine run cooler..(according to his Merc contact).
in the real world I thought the temp of the engine (low side) is controlled by the thermostat....if everything is flowing nicely......the high side should be within a couple of degrees........
did I miss something

Ayuh,.... Without the Proper gaskets, the water flows are altered, causing localized Hot Spots...
These Hot Spots won't show up on your gauge,...
If there wasn't a Need for different gaskets, they wouldn't be making Different gaskets....

But,... Hey whatever,... It's Your boat....
