How-To: Bilge Pump Installation in an RXP-X (Lots of Photos)
I realize there's already another topic, but most of these are for an RXT/RXT-X. This is done in a 2008 RXP-X (which is quite frankly very tight for space).
Most with an RXP put it below the rear toe hook but in a P-X that's not possible due to the Intercooler position...unless you move the intercooler of course.
Anyway, parts list (from memory):
- RuleMate RM750A (http://www.firstchoicemarine.com/p-1...34-outlet.aspx)
- Rule Switch/Fuse Panel Rule 41 (http://www.firstchoicemarine.com/p-1...uto-float.aspx)
- Attwood Thru-Hull 67554G1 (http://www.firstchoicemarine.com/p-3...4-67554g1.aspx)
Home Depot & Canadian Tire:
- 3 lengths 9' long of T-90 14 gauge (Red, White, Black)...not sure why the other how to says 4 colours...
- 1 10' length of 3/8" Wire Protector
- 1 10' length of 3/4" ID clear vinyl tubing (if you can get the one with fibers in it, get that) ...I only used about 2' of tubing
- 3M 5200 Marine Silicone Adhesive
- Zip ties to tie down the wires
- Electrical tape to attach the Wire Protectors to the wire so it doesn't slip around
- Female Quick Connectors (attached with 909 Channel Lock Crimper - Made in the USA - the other standard crimpers are garbage)
- 2 Battery Terminal Connectors (+ / -)
- 2 3/4"-1" Stainless Worm Clamps
- Aluminum Rivets and backing plates
- Solder and heat shrink tubing (to join the pump wires to the T-90 wires)
- Di-Electric Grease (Battery Terminal)
- Corrosion Block (saturated the switch and fuse holder - battery terminal) - Same people that make ACF50 for aircraft fuselages
Anyway...there's no step-by-step here as it's pretty easy, most of my time was spent placing the pump. All I did was find the location (behind the waterbox) soak it down with isopropyl alcohol, dry it, then sit the pump holder in place using 3M 5200. Let it cure for 7 days.
Drilling the hole. I used an angle drill with the hole saw going in reverse most of the way, but basically until you're well through the gel-coat. DO NOT turn on the drill and back it out like I did...close call there, hehe. Anyway, my hole had zero chips...actually better than the factory holes. My thru-hull doesn't require silicone as it has it's own silicone gasket. The hole is drilled in the middle of the angled foot pad...see the green tape pic.
I then wired it up, soldered, heat shrink, wire protector everywhere, right up to the box and to the battery. Where it is joined I electrical taped the wire protector together like BRP does with their joins.
After all is installed I used a great product called Corrosion Block (use it on my snowmobile all the time to stop the aluminum corrosion due to salt and oxidation). It is di-electric and safe on rubber (actually good for it). Anyway, I soaked the switch terminal and fuse holder as well as all the connectors and battery terminals. I also di-electric greased the battery terminals as Corrosion Block blends well with other greases.
After all is said, my position for the pump is fairly decent. It comes on when I'm submarining the XP a lot. I originally hoped it would shoot over the side, but it didn't. However, it's actually good as you'll know when the thing comes on because your footwell will fill with warm water and I really like the look of the location.
See the extensive amounts of photos and the drill videos and pump video for more explanation. Any questions, post em.

More pics...kitteh still hard at workz

Few more...hehe, told you it was extensive
And a couple videos
Make sure you drill a pilot hole first the same size as the hole saw bit (I used 3 step sizes before drilling the hole saw center bit size)
Also, drill is going IN REVERSE to prevent the gel-coat from chipping. I probably went about half way through in REVERSE then switched to forward and used the weight of the drill.
Do NOT do what I did and turn on the drill and pull the hole saw out...I was lucky

Very nice job! Thanks for sharing, one question though, why did you mount your discharge where you did?

Where did you mount yours? ...I see you have an 08 RXPX...

So...the Rule Mate switch failed and was running my pump ALL NIGHT. Water got in it through the casing (not the toggle switch part...it's sealed).
So here's a quick fix...Plasti-Dip!! The stuff you coat screwdrivers and pliers with. You can buy it at some hardware stores.
Anyway...see the pics below...has worked perfectly for probably the last 15hrs.

Nice job and great write up. When documenting the complete process with instructions, photos and videos, it takes probably three times as long to do the job. With that being said, I'm sure alot of members here, as well as others who stumble across this topic from online searches, appreciate all your work and efforts. Again, great job.

Hey ksalles, thanks. Others have done it for me, so I try and contribute.
Ok...so here's a movie of the bilge pumping the water out. It's on a lift and slopes slightly forward so the water is going in the footwell quite a lot. When it's in the water I'd say 60-70% of the water goes out the back.
Anyway, I personally like the look of it where it is...it looks stock in my opinion, I know most put it near the tow hook but I have the X and the external intercooler is there, so I opted for where it is.
