Blower required for diesel?

[Seattle Scott]

Isn't the engine blowing out the exhaust

anyway? I don't understand this blower thing and I am not alone, there is a another thread saying no blower

Heat....

The blower is there only to remove heat from the small compartment the engine is located in. In the P36-2, the Yanmar engine is located under the sink, well insulated and is basically sealed off. When running for several hours, the cabinet the engine is located in, which is under the sink in the galley gets hot. The blower pulls the heat out making the cabin not be affected by the hot engine. The blower is not intended to cool the engine, just remove the heat that is ommitted from the engine. Greg

Greg, sounds like a lot of projects

to keep you busy! My projects are upgrading the electronics and some minor repairs because the boat is in good shape. Trying to figure out the best way to mount a radome. I agree it would be helpful to have an access from the aft cabin - I've been thinking about adding one. I'd be happy to try to answer any questions - sounds like you will have more experience with all your projects. Email me if you like at bdltemp@verizon.net. This is a temporary address I'll be deleting soon but I will give you another address I won't post to cut down on spam.

Engine Compartment Ventilation

Greg’s right. Although the Blower (engine compartment ventilation) doesn’t directly cool the Engine, it does provide cooler Combustion Air. The ideal temperature for combustion air is about 77 degrees F. Hotter combustion air reduces engine power output (about 2% loss for every 10 deg above 77).The engine’s water cooling system will be more effective, if the engine is operating in a cooler ambient environment, and heat gain to adjoining spaces will be reduced.In the tropics, I’ve had my cockpit sole too hot to stand on barefoot, due to rising engine compartment heat.
