What does an impeller do on a boat. To answer to the question what does a boat impeller do This unit pumps cold water into your boats engine to cool it down while in use. A bad impeller can mean overheating for your engine which could lead to engine failure or fireexplosion in the best and worst scenarios respectively. What does an impeller do on a boat.
An impeller is a rotating component of a centrifugal pump which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. The impeller itself is simply a series of rubber vanes molded around a hub. The vanes are flexible and the hub rotates on an eccentric within the pump housing which has a stainless steel liner.
The tips of the impeller vanes can wear out from simple use but if the motor is often run in silty or sandy conditions this abrasive material can accelerate impeller wear. Again this is much easier to do if the pump is off the engine. Some pumps have a key in the shaft which must go into the impeller hub without falling out.
These are very difficult to work with. After changing an impeller run the engine for a while and check to be sure there is no seepage around the face plate or anywhere else. If the motor ceases to produce a steady stream of water after reaching its normal operating temperature the impeller is one of the two most likely causes.
If you just took your motor out of extended or winter storage check the cooling water outlet located at the bottom rear of the motors top cowling. All across the US wasps like to winter in there for some reason. A jet is different than a propeller as the engine will turn the jet a full rpm whether the boat is tied to the dock or running at top boat speed.
Because of this the larger impeller may be used without danger of lugging the engine when the boat is slowed down by heavy loads dirty bottom etc. Since the impeller plays a crucial role in keeping the boat engine cool all the time many say to replace it yearly regardless of its condition so that you need not worry about the engine failure due to overheating in the middle of the lake. It is up to you if.
Your Volvo Penta D4 or D6 impeller is a major part of the engine seawater system which cools the secondary internal freshwater system which in turn cools the engine. The impeller is made up of several flexible blades and designed to move fluid by rotation. How important is a raw water impeller.
Volvo Penta has a long history of successful marine engine design. Their multiple cylinder engines can be found on many of todays pleasure craft and fishing boats. The water pump on the Volvo Penta has an external mounting at the front of the engine easily accessible for the average repair person.
The sea water pump AKA raw water pump. Most of these pumps use a small rubber veined impeller to suck water from the lake to the engine and the recirculating pump then circulates water through the engine block and is expelled through the exhaust and there fore cooling the hot exhaust system. Since the impeller plays a crucial role in keeping the boat engine cool all the time many say to replace it yearly regardless of its condition so that you need not worry about the engine failure due to overheating in the middle of the lake.

If you have a bad impeller it can cause big problems. HOW DO IMPELLERS BECOME DAMAGED. Your boats impeller is a series of rubber vanes molded around a hub.
The impeller has a magnet inside it and as it spins the magnet passes over a corresponding magnet mounted inside the boat on the base of the hull usually in your foot well and this has a wire connecting it to both the under-seat magnet for stroke rate and the box that reads interprets and displays the data. A boat impeller is a series of rubber vanes molded around a small round disc that is used to pump cool water from outside the boat through the engines raw water cooling plumbing which keeps the engine cool when running. -get the stock impeller rebuilt-get a 1319 impeller-get a 1418 swirl impeller Intended use.
This is for my 2000 GTX DI which will likely be used for rapid transit between my big boatmarina and my parents house which is a 10 minute ride from my marina. Or solo exploring around the lake. The repair manual for my motor indicates that when installing a new impeller the vanes should be greased and the housing should be installed while rotating the drive shaft clockwise.
That takes care of the proper orientation. Running it in may not cause a problem if done as suggested in previous posts. I also have never installed the impeller and had to run the boat immediately to test it for leaks as I have never had one leak in the 26 years of owning inboard boats.
Do as you wish with a petroleum base lubricant but to prove it set any old impeller or piece of rubber in a container of mineral spirits which is petroleum based and come back. Vessels using fuel containing alcoholdrain the fuel tanks as low as possible and add a sufficient amount of Mercury Quickstor Fuel Stabilizer to treat the remaining gasoline. Follow the instructions on the container.
Mocked up the new impeller and wear ring. Wear ring went in very smoothly checks out even all the way around. Sucked impeller on and she bound up.
Ended up shimming with 120 total to get 030 clearance all the way around front lip. Is that uncommon to have to shim that much. WHAT DO IMPELLERS DO.
