Jeanneau Voyage 11.2 engine blower???

[goudurix]

On y 1990 Jeanneau Voyage there was a Jabsco bilge blower inserted in one of the flexhose tubes bewteen transom and engine compartment. It was "dead", I've replaced it, new one is also DIA.

On my boat it was installed to exhale air from the engine compartment to outside, and wire to run continuously while the engine is turning (via the ignition switch and a relay).

Is this an add-on or originally installed???

Why is it installed? To ventilate the engine compartment when running in hot outside temperatures?

Usually these type of engine bilge blowers are installed to exhaust gasoline fumes in gasoline-powered motorboats.
I have never seen it on sailing yachts this size (37 ft).

Thanks for any help,

On a lot of Yachts not just Jeanneau for example Westerly 1990 etc have engine compartment blowers, on my 35 (2003
) I have 2 outlets in and out on the stern either side of the removable gangway. It is powered when the engine is running to extract any diesel fumes or engine smells from the compartment. As the engine is hidden behind the steps into the galley, fumes and smells would escape.

With regard to the DOA blower, I take it you have checked the electrics with a tester and also any fuses in the engine area, I am not familiar with your yacht but if it was retro fitted there may be an aux switch on the control panel not labelled and also there could be in-line fuses on the cables between the fan and the ignition.

Hopefully someone else with more knowledge can shed light on your problem.

Thanks C-Spirit, well I still think it's a bit strange to have it blowing all the time the engine is running.
especially when this type of blower is rated a limited number of hours of lifetime. The replacement one I have installed certainly hasn't done 1000 hours yet (I estimate about 250-300 hours).
The fuse is OK but still I do not measure any voltage arriving at the relay neither at the blower which is really puzzling me.
I will take out the blower and dismantle it to check the DC motor. If it is still running or can be repaired, I will rewire it through a standalone switch, so I can run it when I want, in hot outside temperatures, and for about 15 minute after longer engine use.
