Turning off engine blower

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Is there any reason why I can't put a simple switch from the engine blower to turn it off? The noise drives me mad and I have heard that it is only there so that the boat complies with EU regulations or something similar. 

I can see no real danger or disadvantage in doing this.

	Yanmar is recommending certain temperatures for the engine room. This is also related to efficiency and long time wear. It is simple to say that cooler is always better. The engine would also work in a hotter enviroment but less good. Why should you switch that off? Doesn't make sense to me. BR Thomas

	Which engine blower is build into your boat? Some time Hanse used a very noisy but cheap fan from attwood for this. I changed it to one from plastimo. It is totally diffrent now! The sound of the old fan was much louder than the engine itself. The new one is not audible when the motor is running!

	For the maiden trip I was really nerved about he noise, I bought a switch to turn the fan off for manouvers in harbour. For longer motor trips I switched it on and i measured that temperatur is going down. After te maiden trip I had few complains, one was the fan. Hanse changed it to a more quiet one and now I'm happy with the sound.

	When you run a 2 liter engine at 2500 rpm, you get a turnover of 5,000 liters of air per minute and it should be more than enough ventilation in the engine compartment Edited by Idelfix - 04 July 2011 at 19:22

	I cannot see or hear an engine fan on my 320. I have vents in the companionway which supply air down to the engine. Charles

	Our blower is very quiet, we hardly hear it but it does work, I occasionally hear it coming from a vent in the stern, I think the cheaper ones are the noisy ones! Edited by trist33 - 29 July 2011 at 10:34
