Kracker I don't want ya to think I'm raggin on ya...I'm actually envious of your skills, so take the following as food for thought...not criticism...I'm glad to hear yer gonna put a floor hatch ahead of the sump for bilge pump access...but at the same time on pump size; THINK BIGGER...500s are for bait tanks and paddle boats...a grand in the sump and a grand in the bilge are better selections...and even bigger won't hurt... We took a 17'er 35 miles off Charleston one day and had perfect seas(as forecasted) until we were in sight (5 miles or so) of the jetties when we started taking waves over the windshield one of which took the hat off my head...and I bet ya Macojoe seriously doubted having his windshield destroyed and cockpit FILLED close shore either...some days, that's where the poop gets in the fan...I ain't waggin' a finger here...just tryin' to keep ya safe...

Kracker, I allways tell people to go at least 2000 on their primary pumps with teh 1 1/8 smooth wall hose, bilge pumps are rated with no hose, no head pressure, just free flow and at 18 V. WHen you drop it down to 12 v, your cutting flow by about a third, when you hook hose to it with any rise, it probably drops another third, its said that the corrigated hose cuts flow in half. Years ago, one of th boating magazines did some test to confirm this data, it was worse than they thought, I wish I still had that article, I've sure quoted it enough. I run three 2000 GPH pumps on my V, each one with a direct lead to a high amp(20) rated float switch and directly to a battery, I run an indirect on/off switch as well, two of the float switches are in the bottom of the bilge, I have indicator lights on these, the third flaot switch is raised bit off the floor and is hooked to an alarm and light. IF you think youhave enough pump capacity, next time you go to the ramp, leave the pug out when you back it in, see if your pump can over come the water coming in thur a 3/4 hole, imagine what a thru hull broken off, or even some kind of hull breach would allow in. Oh and by the way, I've found the average life span for most pumps is about three years, just after the warranty runs out. Just food for thought

X2 What Spare said. The GPH rating system on pumps is well overstated. I have one 1000 and one 1500 Rule's in the bilge of my 20. One of the automatic switches is higher than the other. I can put a 3/4" garden hose at 60 psi loose in the boat. The first 1000 GPH pump comes on, pumps the water out and turns itself off. If the second one kicks in a light and alarm sounds to warn of high water in the bilge. I have heard the alarm during testing but never on the water.. I try to keep the bilge clean so nothing can jam the impeller. I am OCD about the pumps on this boat. When either one of them die, I am going to upsize again. I started with an 800 and a 1000.

Started stripping the t-top today after work. LOADS OF FUN!!!! I devised a mounting plan for the top. Im gonna have to extend it in height by 4 inches and fabricate base plates. Then fabricate some standoff brackets for mounting it to the side of the console. Then bring it to my welder to get it glued together. i can weld but cant weld aluminum!!!!!

Looking good Kracker!
And x3 what everyone is saying on bilge pumps. I wouldn't trust a 500gph bilge pump at all. On a second note, i have decided to keep my V20. Now, its a cuddy cabin, I want a center console. What do you think of gutting it and rigging it like yours? I showed dad some of the pictures of yours and he likes it. I believe all my stringers and transom are in good shape. I have the console and bow rails from the 18 i planned to rebuild. I just dont like the cuddy and the useless livewell in the floor.
