Does an outrage 18 have a bilige pump?
If so, where should it be mounted.
Any thoughts..

An Outrage does not necessarily have a bilge pump, but most do. I certainly recommend one. There is a deck pry out in the stern starboard corner of the cockpit sole which covers the sump for the bilge pump. The discharge hose then run out the tunnel with the other cables and wires and then either goes to a through hull or over the transom or, I think, better yet just into the splash well where it will simply drain out. This keeps the hose very short and the set up very simple.

Tom, how does the water run out of the splash well? My 84 Outrage has the drian holes at or slightly under the water line at rest. Also didn't we have a earlier discussion on this? I got responses to leave my sump plug out at the mooring and let the water seek its own level.
Would like more input as this weekend will be the first time I leave my boat on the mooring throughout the week.

Bilge pumps are a convienence for 99% of the time, but for that 1% , when you take a wave over the bow and are ankle deep in water, it makes no sence to pump water from one part of the boat into another. The drains will not move water as fast as a good pump. So save yourself a few grey hairs and install as large a pump as you can, and move the water outside the boat.
On my Outrage, I have an old 750gpm with a 5/8 hose over the transom, secured to the motor mount. Although a Whaler will not sink, I feel better with the water on the outside, and dry on the inside.

Yes the splash well drain holes are at or below water level but if you pump, say, a gallon of water from your bilge into the splash well which already has water in it, the water level in the splash well will rise above the water level outside the boat. Since water seeks its own level a gallon of water will necessarily drain out the drain holes.

This brings to mind the other advantage of pumping into the splash well. You can visually monitor what is being pumped out of the bilge instead of having the bilge water simply dissappear behind the transom.

Yes there was a previous discussion on plug in/out but here's my thoughts. You can leave the plug out of an 18 and it will float. It will most likely float with the cockpit sole above water level. (Mine did and I had a 150, a 9.9 kicker, and two bateries) But there will always be water in the bilge which includes the area where the drain plug is, the bilge pump sump, and the tunnel for the rigging as well as any voids around the fuel tank. I know the tank is foamed into place but there is still quite a bit of volume in the above mentioned areas. If the plug is left out all these areas are susceptible to marine growth. I don't like the idea of slime and barnacles growing in my bilge!

When I bought my Outrage I was looking forward to being able to leave the plug out all the time because, unlike my Montauk, it floated with a completely dry cockpit. The first few times I had the boat out it seemed to take a while to plane. I thought this was odd since I had a 150 on the back. Then the first time I went fishing I took three others with me and quickly became apparent that if we were towards the stern there would be a lot of water in the cockpit! So I put the plug in and turned on the bilge pump. It seemed to take forever to pump the bilge. When we finally headed for home I cranked up the motor and it seemed to jump up on plane and it occured to me that, duh, there is a huge amount of water in the bilge when the boat is at rest and all that water weights a lot. I never again left the plug out. A dry bilge is a clean bilge. The boat will also float higher exposing less of the bottom to marine growth and if you have bottom paint the water line can be held lower.

Thanks Tom, I am re-thinking the plug out theory. Maybe just over the weekend, and then put one of those fully automatic pumps in. Your suggestion makes alot of sense (I was thinking the same).

The bilge pump option for the Outrages was a 1500GPM Rule, with separate float switch. Cost about $150 extra. Don't go smaller than an 1100GPM model.
