OK GR8,
Here's some pics that I hope will help you. I'd forgotten that you'll need to cut hose for valve so, you'll need probably 3 more hose clamps including one for overboard dump hose. Oops! almost forgot, when you drill holes for outlet and switch, use a 7/16" wood boring bit. It is a little small but, you want fitting tight going through hull. You'll have to "wiggle the bit around a bit to get it hogged out just enough to get fitting through. It WILL BE TIGHT. That's what you want. Use a little silicone sealer on the in-hull portion of "L". Then a little on the on deck portion. When you get it good and tight go ahead and seal around where fitting contacts the deck. Now it'll be water proof. Do same thing with your switch I used a 7/16" wood bring bit for that and did the same thing. Remember you want it tight. You'll have to work at it to force them through the holes. Works good, lasts long time!
Also, with you electrical connections, you'll need some liquid electrical tape. Applied after you make connections it will make them waterproof. You need to try and keep wire high in the hull so its not laying in the water all the time but, any gaps in connections should be covered liberally with the stuff. It may not be as important in your fresh water use, but I don't want or need any salt water getting into little nooks and crannies. Anyway the stuff works great! Be careful, it can be messy. Several light coats work better than a big heavy one, and no where near as messy. If you spill it, let dry it will then peel off easily.
If you need more info just holler. I'm not going anywhere. I still have to connect wiring and test the pump. To do that I'll just fill a small bucket with water, unsnap pump from base, put it in water and turn it on and watch water flow (I hope
)
