    I’m looking for tips, ideas, suggestions, etc., on the design of the bilge area immediately under the engine. This is new construction so I have a clean slate to work with (the engine is a Beta 75 hp). Questions in my mind have to do with clearance under the oil pan, bilge drainage, and oil containment. This may not be a critical detail, but ideally, how should this area be set up? Any input is appreciated.

    Regards,

    We need more specifics- are you just asking how the area should be built?

    Danny,

    I'm interested what needs to be considered in this area...for instance, should drainage from aft of the engine just run directly under the engine, or should I laminate a couple of pvc drainage to the keel and then form an oil containment sump around the engine. I would like to get the engine down as low as possible, but am wondering if I may be overlooking something. I'm not thinking I'd want to drop the oil pan, but you never know if the gasket might leak. The Beta engine has a built in oil change pump so I wouldn't have to get a the drain plug on a regular basis. As I said, it is not a critical issue, but I thought I'd check to see if anyone had 2 cents to say on the subject.

    Regards,

    SeaJay

    Seajay,

    do you have enough room under the engine that you may access for maintenance or cleaning purposes,if possible, you may create your oil collecting tank install a sump pump and connect to your discharge system for waste oil.

    cheers!

    North Stream,

    I have considered what you have suggested. If I use the Beta engine, this should not be necessary on a regular basis as the oil change system is built into the engine itself and is accessable from the top. A containment sump could be handy but would limit access to the area below the engine.

    One thing I should have mentioned is that the boat has a "canoe" shaped hull and is very flat in this area (both forward and aft as well as athwartship),making for minimal clearance underneath.
