water under engine bilge 36 sed bridge

[Fitzroy]

New vent covers to prevent rain water and sea spray getting in to bilge and over the diesel tanks

I get quite a bit of water in the bilge area under the engines when it rains( both sides). It fills up and cannot drain to the main bilge area which has a pump located between the engines. (I cannot believe there is not drain to main bilge from this site) I have 380 qsb 07 build. The dealer has had a few goes but cannot find out where the water is comming from. I suspect it might be comming from the side vents. I am going to test this theory next time it rains. Has anyone with this model experienced similar problems Thanks sydney australia

Aren't you worried about blocking the air flow? I know my QSM-11s are air starved as it is and I can't imagine blocking those vents. You should look at your engine's boost pressure with and without those things installed and see what kind of effect it has on the engines.

The photo does not show the cover clearly. There is a large opening at the bottom. The surface area of the opening is actualy larger than the openings on the original cover. I measured and calculated the surface area. The cover is deeper than original. There is more air flow now than original. The major advantage is that water does not get in through the vents during heavy rain or offshore waves-spray. I have tested it at 25K 2600 RPM and boost pressure are same as before

That's cool... just wondering.

They look nice.
