Bilge Blower(s) on the 25D

Post by Jim Westpfahl »

Noticed that our 1985 25D needs to have the 3" vinyl venting hose replaced. I wonder if the mild but still quite obvious diesel smell in the cabin would be reduced if I were to place a bilge blower in one of the hoses. If so, do I push air into the engine area or pull it out? Any opinions or thoughts about the noise level and efficiency of the Atwood in-line blower VS the PAR Marine blower? Any recommendations on the location of such a blower?
Any advise is much appreciated.
Jim

Jim: The bilge blower should be set to blow out, not in. If you blow in, you simply spread gasoline vapor or diesel smell all over the interior of the boat.

I don't have a blower, and there isn't any diesel smell in my 25D, which has the two 3-inch hoses leading to two ventilators on the aft deck. One cowl points forward, the other points aft, and they set up a good flow of clean air through the engine compartment 24 hours a day. If you have a persistent smell, is it possible that you have a fuel leak? I presume you have the Yanmar 1GM10, which is a very clean engine, and I can see no reason why you should have to install a blower.

If an old diesel fuel spill has contaminated your bilges, you should scrub them out once or twice with a solution of two or three spoonsful of trisodium phosphate (TSP) in a bucket of fresh water. Any good hardware store will have TSP, or its substitute.

If all your systems are working properly, there should be no smell and no need for the complication of a blower.

Jim, I had the same problem with my cd25d and cured it by installing a solar vent in the cabin just forward of the mast. The secret is to set it up pulling fresh air into the boat which forces the smelly air out of the engine area. It works great! Dennis CD25D "serinity"

I would check all fuel lines and any filter for leaks. I do not have a diesel odor in my 25-D. Though I don't have a blower in bilge, I do have a solar vent. However, I attribute the absence of diesel odor to a leak-free environment.

Jim,

Make sure the plastic hoses are still attached to the ventilators. Last year after having diesel odor permeate the entire boat, I discovered one hose disconnected from the ventilator. The boat was free of odor by the next weekend.

Another wonderful cleaner and also to get rid of the smell is diesel is white vinegar! Gets rid of the smell almost immediately.
