“[quote=paulfleming;450][quote=PH4;448]We have a 1996 Intrepid that has the switches for a macerator, second bilge pump, and freshwater wash down but none of these was added/installed as an option when the boat was originally purchased from Intrepid. We now wish to install these options and would like to know how they would have been originally installed. Please see questions below. Your help is appreciated.

1) Would you please tell us if the macerator was originally installed inline with the below waterline hose from the fish box that drains through the below waterline thru-hull on the transom or do we need to run a new discharge hose from macerator to above waterline and install a new above waterline thru-hull similar to the one for the bilge pump.

2) where exactly was the optional second bilge pump placed in the bilge and the float switch for same. Do I need to T the hose from the second bilge into the hose from the first bilge or run a second and distinct hose installed into a new separate thru-hull. I am adding a second Rule 2000.

3) where exactly was the tank and pump for the optional freshwater wash down installed on the boat. Who built/supplied the tank and pump and what size was the tank and pump.

4) do you have a wiring diagram for the boat you would provide to us. It would help a great deal.

5) what hatch tape do you use for your hatches.

5) thank you for all of your help with this project. We are very appreciative of Intrepid’s willingness to help provide assistance and parts during the project. We love the boat and could not be more pleased with it and hope to acquire a 32 in the near future.[/quote]

Hello and thank you for using our forum; I look forward to assisting you thru your projects.

  1. The macerator that we use for our fish boxes does get installed inline with the drain hose below the waterline using a PVC Tee; however there is an additional discharge hose that will need to be added above the waterline. This gives you the ability to drain water manually when the boats is lifted out of the water by opening the seacock’ or by activating the macerator switch and discharging it overboard with the seacock closed.

  2. The second bilge pump would be installed in front of the currently installed pump at the same placement (this allows the pump to discharge as much water as possible). The float switch for the second bilge pump should be placed a few inches higher that the original float switch; this will make sure that both pumps are not competing with on another (when the bilge pump turns off there is so water that will flow backwards thru the hose, if the float switches are at the same height the possibility of the pumps cycling is high). You will need to add an additional thru hull for the second pump.

  3. If an optional water was installed during the build process it would have been placed under the deck. At this point to add a freshwater system you would have to measure one of the deck hatches in a storage locker and install a tank or bladder bag there. As for the pump I would recommend the Shurflo Aqua King II (5 GPM).

  4. Unfortunately we did put wiring diagrams in the hull file as we do now. However if the console switch panel has a switch for the freshwater or macerator there would have been a wire run into the bilge and “”dog boned”” for future use. Look around in the bilges on the bulkheads and on the underside of the deck to see if you see a bundle of wires secured (they should be labeled with the specific function of the wire).

I am going to send you a reply via your email with some pictures of an installed macerator and dual bilge pump installation.

I meant to also ask about engine mounting. My 1996 originally came with twin 150 Mercury EFIs with 21P Laser props. She now has twin Optimaxs with 19P Tempest Plus props. The original EFI engines pulled 5,500 RPMs and ran 56 MPH when Intrepid originally sea trailed the boat.
The Optimaxs (they have less than 80 hours on them) will only achieve 5,000 RPM and about 48 MPH. In addition, the boat porpoises unless the trim tabs are all the way down. Even trimming tabs up a touch results in porpoising. Any thoughts or advice? Does the boat need wedges? Do you suggest different props. It is an excellent boat and rides well but we need to get the RPM and porpoising issues solved. Thank you for all of your help.
