Marine Plumbing & Ventilation The plumbing and ventilation systems are two of the most important aspects of your boat. It is very important that any toilet facilities work properly, and you also need to ensure that there is adequate ventilation for the engine and to remove any fumes that can build up in passenger compartments or similar areas. With our marine plumbing and ventilation parts and accessories, you have what you need all in one place, right at your fingertips. From air conditioning & refrigeration supplies to bilge pumps, fans, and hot water heaters, we have it all under one roof.   We carry several brands and can offer Livewell pumps and transfer pumps, along with several marine sanitation options. Portable toilets are an excellent choice for boats that are large enough to accommodate them, but the comfort of your passengers is not the only thing to be aware of. You also need to make sure you have adequate engine cooling pumps, and that any washdown / pressure pumps work correctly. With a WaterMaker pump, quality fittings, and the right blowers & heaters for your boat, you can ensure that your boat will operate correctly and your passengers will have the comfort and convenience they need.

Headhunter THR-3.75" Impeller

  Check all of your impellers contained within the engine cooling pumps, bilge pumps, ballast pumps, and so on.  One of the biggest contributors to impeller deterioration and damage is sitting idle in the same position for several months, so a proper check of the impeller(s) is vital to a reliable operation of the boat after storage and/or no operation.   Replacing an impeller is a fairly easy and straightforward process and one that you have probably done in the past. It is important to use the right tool to remove an impeller from the pump. Channel lock or needle-nose pliers are fine, but using an impeller removal tool is the best choice.  Never use a screwdriver to pry an impeller out of a pump; you could accidentally score the bronze housing which can lead to leaks.  Make sure you know how the impeller is being held in place.  Some are sealed to the shaft with an O-ring; others are held in place with a set screw and others with a c-clip.   Make sure to check the pump and the water lines for any trash or chunks of rubber that may have broken off from the impeller.  Even the smallest blockage can cause major engine cooling and overheating issues.  Also, remember to properly lubricate your new impeller with Vaseline or the lubricant included with the new impeller. This will reduce friction for a brand new impeller on a dry startup.   Most importantly, make sure you are using the right impeller for the application. We have seen many instances of people who have replaced an impeller with something that is close to the original, but not exactly right, and this can cause major problems for the engine once normal operation resumes.  You cannot match the size of the used impeller to a new one to determine the replacement, as a used impeller can be swollen and disfigured from its original specifications.  The best method is to obtain the impeller number off of the impeller itself, usually located on the edge of the shaft hole of the impeller, or obtain the part number of the pump, usually stamped into the bronze housing.   You can find just about every impeller that needs to be replaced at CLR Marine.  We carry Sherwood, Jabsco and Globe just to mention a few. We also carry many of the miner and major rebuild kits for many pumps.  A minor repair kit consists of the impeller and any gaskets or O-rings that may be needed to replace the impeller.  Our major rebuild kits include everything to rebuild that pump except for the shaft.  All kits are put together at time of order so you will always see the Quantity on Hand as 0.

Impeller Kit Material:Neoprene Drive Type:Spline Drive Number of Blades:12 Dimensions: Diameter:2-1/4" Shaft Width:1-1/4" Shaft Diameter:5/8" Insert Material:Brass Jabsco flexible impellers can be fitted to most makes and models of bronze flexible impeller engine cooling, bilge, transfer and general purpose pumps. Jabsco flexible impellers are subjected to rigorous quality processes to ensure reliable, efficient and long lasting performance. Replace all impellers at least once every year, or sooner, depending on the engine duty. When the installation is correct an impeller may last for several years, but it is always advisable to stick to a schedule of preventative, rather than corrective, maintenance. Replacing impellers is easy. By removing the end cover screws, it is possible to remove the impeller by using either a Jabsco Impeller Removal Tool, or channel lock pliers, to grip the hub of the impeller. Don?t use screwdrivers as they may damage the face of the pump body, causing leaks, and they can be dangerous in confined spaces. Always carry spare impellers on board in case of emergency. The impeller is one of the most vital components of the engine cooling system and should always be treated as such. Always grease new impellers. Firstly, it makes it easier to install the impeller into the pump bore, and secondly it gives added protection to the impeller during initial prime. After replacing the gasket and end cover the pump is ready to use. WARNING: This product can expose you to chemicals including LEAD which is known to the State of California to cause cancer, birth defects or other reproductive harm.
