Blige pump vs drain plug

Re: Blige pump vs drain plug

In 1997 I purchased from Cabela's a "Super Plug 1" boat drain plug. This cable lever mechanism allowed me to operate the drain plug
from inside the boat and from not standing behind and under the engine.
Does anyone know where I can purchase another one as Cabela's has discontinued this item.

Re: Blige pump vs drain plug

I would be really wondering about the water inside your transom at this point. That is if this is actually where the water is entering the boat. And buying the cheapest bilge pump is not really a wise choice either, especially when we all know that while under way everything that flies around will eventually end up down there. That rag down there in the picture is a perfect example of what I'm talking about. That's bad, that rag could cause your pump to fail if it stops the motor from pumping. That's the kind of stuff you should be inspecting almost every trip out! I've burned a couple motors out by letting crap collect down there, keep it clean down there so nothing stops that bilge pump from operating. They are usually very poorly built and fail on a regular basis, so it's up to you to make sure it is working well, it's rather important IMO.

2008 is not that old, neither is 86 hours (17 hours a year is not boating!), at least it wouldn't be for a coastal boat. But it is an I/O with their own brand of problems.

Pulling an engine to replace a bilge pump is just crazy. Hook up a new one, bypass the old one, put it where you can get to it like it shuold have been at first.

I've had to do this. +1

Yea, I thought pulling the engine is a little over the top since I can't even find half the stuff I'm looking for right now ;-)

Re: Bilge pump vs drain plug

Ok, I found the bilge blower motor but I'm confused about the hose routing. On the back of my transom
is two exhaust holes but I only have one blower motor. How does that work? The hose is busted so I
can't follow the old path. Should I just buy two blower motors and run each on opposite sides of the bilge?

Re: Blige pump vs drain plug

One Blower is correct. There should be a hose from the suction side that goes all the way down to the lower third of the bilge. It sucks any fumes out of the bottom that may have settled. Fresh air comes in the other vent. Some plumb an additional hose from the other vent and down into the bilge as well. I don't believe that is legally required, and seems like it would cause less "bilge" air to be sucked out as fresh air could transfer from one hose end to the other. Legal requirements:

Starts on page 30, top of 33 is specifically relevant to your question.

Re: Blige pump vs drain plug

ONLY exhaust vents are plumbed to the bilge. Intake, is simply supplied to the upper portion of the engine compartment. Routing intake to the bilge would stir up any fumes making it harder to evacuate them. Often there are exhaust vents only and intake air comes from the interior of the boat.... You have to look at the individual boat to determine how they worked it.

On a small boat though one blower is very common and a second exhaust vent without a blower is also common. It comes into play when boat speed is high enough for engine compartment to self ventilate

Re: Blige pump vs drain plug

I agree ^^^^ just some here have argued for two hoses. I have never seen it on a new boat and the guidelines suggest otherwise.
