Dorades too low in stack?

[CaptFun]

I have a "tint tug" with a 4 cyl. keel cooled diesel. My intake and exhaust dorados are well below the top of the stack. Should I add a bilge blower to the intake dorad blowing fresh air in the engine room to increase the air exchange and thus decrease the temperature of the engine room??

Many thanks

Much better to suck the heat out, as pressurizing the ER will cause the ER smell to fill the boat.
