Author Topic:   Remove engine well dam on 18-Outrage

ECUSeaPA posted 01-27-2002 11:00 PM ET (US)
Does the built up wall (4" - 6") running the width of the boat about 18-20" from the transom have any structural aspects or is it there to prevent water fro coming up the boat? Can you remove it??
Thanks for help!

That wall is all foam inside. My 1987
Outrage 18' had something mounted on it. when I drilled out the screw hole to plug, all I hit was foam. I think there is wood on both ends of this wall since the heavy duty cleats above it are not thru bolted to the sides of the boat. Hope this helps.
Never scared

I don't claim to be a Professional Engineer or to have analyzed the structure of a 22-Outrage, but the last thing I would modify would be that engine well dam wall.
My instinctive sense of its function is to not only provide a dam for the engine well water but to also add rigidity to the whole transom area structure. Bending the cockpit floor up and over that wall adds strength to the area. Cutting it out and replacing it with a straight floor section--even if done well--would probably not create as much strength as that wall does.
It is the same principle that gives corrugated cardboard more rigidity than a stack of kraft paper the same thickness.
In any case, why would you want to remove it?

Thanks jimh, that's what I was looking for.

Why would one wish to remove it?? I don't get it. Please advise. D

If you closed in the transom, added a bracket, and removed the wall, you'd add 2 extra feet to the cockpit area. That space is really wasted presently and I really don't like notched transoms.

I still don't get it. If you want extra bracket length then just add the bracket- walla 2 extra feet. Closing in the transom to add the bracket defeats your purpose, seems to me. No? David

CPA - (hope you don't work for Arthur Anderson!) I accomplished what you are talking about in my 18 Outrage, but would NEVER consider removing the splash rail. Incidentally, there is 1/2" plywood under the entire top surface of this. See Jim's Reference section, engine brackets, for pictures.
The setback brackets allow you to get all engine cabling out of the splashwell, which then can have 1 1/4" drain plugs inserted and a 800gph bilge pump installed in the lower sump. Now you have a large, dry, additional area for coolers, tackle boxes, etc. Works very well for me.

Been busy with taxes (not at Arthur Anderson!!) and have not checked back. Like what you did lhg. Where'd you get the brackets and what would a single run? That really cleans up the splashwell. Perfect!
