DIY Electronic Bilge Pump Switch

Every boat needs a bilge pump, but a bilge pump does not make any use if you do not have Electronic Bilge Pump Switch installed in your boat. This is uually the case with small and older boats. If you buy a new Electronic Bilge Pump Switch today it will cost you quite a bit compared to how much you will spend to make a Electronic Bilge Pump Switch yourself at home.

A while ago I was contacted by the owner of He published a simple tutorial to make your own Electronic Bilge Pump Switch and asked me to publish it on my blog. I liked the idea, becouse it is a very innovative product and most of DIY enthusiasts will know how to build it. In fact it is very simple so I am sure anyone can build it.

Making a Electronic Bilge Pump Switch

Over the years, I have installed several submerged float switches in the bilge of my boat. They’re supposed to run the bilge pump when the level of water in the bilge exceeds a certain level and then stop the pump after the water level is lower. They usually work well for the first year or two but inevitably fail. Sometimes they fail simply because they’re submerged in water constantly and they had a very small leak. Other times they failed probably because I left them underwater over the winter and they were frozen.

To improve upon this I wanted to switch, pun intended, from a submerged mechanical switch to a solid state, adjustable switch. I wanted to be able to remove as much of the switch from the water, hoping to extend its useful life. Of course there are a few commercial switches available but they’re not always customizable. Also, buying a packaged switch wouldn’t teach me anything about the circuitry required or give me the intimate knowledge on how they work.

Make Your Boat Less Of A Target To Potential Thieves

Make Your Boat Less Of A Target To Potential ThievesYou would be surprised by how many people don’t follow the simplest of rules. Don’t leave valuable stuff like dive equipment on deck in plain view of every passing fishing boat.

Don’t leave yourself out on a limb. A robber will feel far more confident of boarding a boat that is anchored away from the other boats in the harbor. Anchor within view of the other boats at anchor.

Most robberys occur after dark and therefor a dark boat with no lights on is a much more attractive proposition to a would be thief than the boat that’s well lit up. A few years ago this was heavy on the battery banks but with the availability of LED technology this is no longer a problem. You can make them yourself for just pennys or buy them from the marine stores.

Whilst we are talking about lights, your spotlight or”Q beam” is valuable deterrent. If you see something suspicious in the harbor, light it up. If you are about to be boarded shining a 1,000,000 candle power light in their faces can scare them away and certainly ruin their night vision giving you more time to control the situation.

Dinghy engines are always a target so lift your dinghy at night and lock it with a chain or cable and a padlock to the boat. It is advisable to lock your dinghy to the boat when it is sitting in the water behind the boat and always lock it to the dock when you go ashore. 99% of all dinghys and outboards that are stolen have been left in the water and not locked.

Bimini boat top covers guide

Bimini boat top covers guideI quickly covered bimini tops in one of my last posts where I was writing about 10 Thing You Should Have On Your Boat. If you have time I suggest you red it and post a feedback if you think I missed something important.

Bimini tops can make a real difference in your boating comfort. They can very well protect you from direct sun and rain. Putting a bimini on your boat means you won’t have to be exposed to the direct sun while you are sailing around. You can build a bimini on your boat if you’re willing to invest in some fabric, aluminum or stainless steel tubing and a few fittings. All the needed materials can be bought online.

How to Select Your Bimini Top

Bimini boat top covers guide


Decide what length you need, 6′ or 8′. Be sure not to order a top that is too long. When you order your top and fix it on your boat I suggest you step away from the boat and check how it looks. If its too big try to change your newly bought bimini top for a new one.


Measure where the top attaches on one side of the boat to the same location on the opposite side of the boat. This measurement is not the same as the beam of the boat or boat width. This is the most important measurement becouse if you do it wrong you won’t be able to change anything later.


The correct height is one that enhances the good looks of the boat and is functional (so you could stand under it if desired).
