[I plan to] install a small pump in the [cockpit sump] area on my Boston Whaler Montauk. The problem is that area is somewhat congested with cables. Is there a standard area to install the pump? Is there a standard procedure to installing a electric pump? Can I wire it through the [rigging] tunnel to my battery which is in the center console? |

Which Montauk, the recent 17'0" or the 16'7" classic? With the 16'7" classic, at the aft end of the tunnel, the I like the Rule smart pumps. They run for a few seconds, and Use hose with a smooth inside. It flows a noticeably better On the 17'0", it's also possible, but I don't remember the details.

The electrical details on installing a cockpit sump pump are shown in an article in the REFERENCE section. See http://continuouswave.com/whaler/reference/bilgePump.html The small centrifugal pumps often used in this application have very poor ability to self-prime or lift water into the pump, so the pumps have to be installed in the deepest part of the sump area so that they will always be covered with water. The usual location for a cockpit sump pump in a Boston Whaler MONTAUK is in the deepest part of the cockpit sump, which is at the rear of the rigging tunnel. Most of the small centrifugal pumps can be mounted to the deck there. Be sure to use proper sealing techniques on the mounting screws so that water will not have ingress into the hull. It is common practice to run electrical wiring through the rigging tunnel. There is really no other path for electrical wiring to pass from the center console to the stern on a Boston Whaler MONTAUK. |

Thanks to both of you for your great replies. Chuck--you talk about making a hat. I am confused. Yes, I have a 1989 Montauk with tan interior. [Shifted the topic to one which is not related small boat electrical systems. To discuss soaps and cleaning agents, please use the REPAIRS/MODS discussion.

There's about 1/4" between the top of the pump and the bottom of the hatch. A hat, about that thick, will hold the pump in place without drilling any holes in an area that's always wet.

A small dab of matineTex will hold the bas down as well. I have found that I can wedge he rule500 pump in between rigging wires and securing it that way. Avoid drill this area if possible. |

I used an Atwood 400 GPH automatic pump in my old Sakonnet. It was a little larger than the regular pumps. It fit in the sump rather tightly with all the other rigging. I wired it with a standard on/off switch. When I turned it on, if there was not enough water to actuate the float switch, it would stay off. It came on as a normal pump if the water level was high enough. I used enough wire so that the pump could be lifted out of the sump for cleaning or when adding/removing other rigging. When bay fishing, I would install the boat plug from the outside. When fishing the ocean, I would install the plug from the inside. In an emergency, if the boat took on water beyond the capacity of the pump, I could quickly evacuate water from the boat by removing the plug and pulling ahead as quickly as possible. This was a very simple system that worked great for 15 years. I think I replaced the pump once in that time. Doug |

You will want to be able to access the pump for cleaning and repair. My observation over the years has been that there is a high probability that any debris or gunk in the boat will end up in the pump and need to be removed at the most inconvenient time. John |

I am putting in a Rule 500 but not the smart one, this weekend. We got something like a float switch but it senses the water. It is tight in there. My main concern was still being able to get the plug out in a hurry just in case we take on a "boat load" of water. Whats with the rigging tunnel anyhow? It's got a lip on it that prevents some of the water in it from draining into the bilge. John |

In response to my dislikes of the pump mounting locations on the classic Whaler, this is how I have addressed this issue. |
