look under carb your shift set is there remove carb then remove the 10mm bolt
you may have to shift in to forward for better acess to the bolt now the gearcase can be removed
First, remove the lower unit (there is a housing for the water pump). The drive shaft goes through the housing and turns impeller. Remove the housing, the impeller is on the shaft. Install the new impeller. When replacing the housing, turn the drive shaft clockwise to make it slide down over the impeller.
To change the water impeller on a 1988 25hp Johnson boat motor, first, make sure the engine is cool and disconnect the battery. Remove the lower unit by unbolting the screws and carefully sliding it off. Take out the old impeller from the water pump housing, clean the area, and install the new impeller, ensuring it’s oriented correctly. Finally, reassemble the lower unit and reconnect the battery, testing the motor to ensure proper cooling.
To install a water pump in a 1995 Johnson 150 hp outboard, first, remove the lower unit by disconnecting the shift linkage and unbolting the lower unit from the powerhead. Next, take off the water pump housing by removing the screws and then extract the old impeller and housing. Install the new impeller and housing, ensuring the impeller is properly seated and lubricated. Finally, reassemble the lower unit, reconnect the shift linkage, and test the pump to ensure it's functioning correctly.
You need to remove the venturi from the jet pump housing by removing the steering cable and then the reverse cable (if applicable) Then remove the four nuts holding the pump housing to the seadoo. You will need to pull on the housing to remove the drive shaft from the impeller pinion, just pull staight back. Once the Pump housing is removed, there is a tool available from Seadoo, with 18 splines in it. Insert tool, and use a ratchet or impact wrench and unscrew the impeller from the craft. Hope this helps.
The water pump is actually called a impeller and is located in a pump housing where the bottom radiator hose connects. You will need a special socket tool to remove the impeller once inside the housing.
Remove the starter (3 bolts) then you will see the shift rod under the carburetror. remove the screw connecting the shift rod. there are 5 bolts holding on the lower unit remove the bolts and the lower unit can be removed. then you cam remove the water pump housing and replace the impeller.
To change the water impeller on a 9.9 hp Tomos Traveler, first ensure the engine is off and cooled down, then remove the lower unit by unscrewing the bolts that secure it. Once the lower unit is detached, take out the old impeller from the water pump housing. Clean the housing, install the new impeller ensuring it is oriented correctly, and reassemble the lower unit by reversing the disassembly steps. Always refer to the specific service manual for detailed instructions and torque specifications.
The impeller on a 9.8 Mercury outboard boat motor can be easily changed. Remove the retaining bolt. The impeller will come off. Reverse the process to install the new impeller.
remove the lower unit of the motor (the part with the prop attached to it) by loosening the four bolts which hold it on, as you are doing this be carefull to hold the lower unit in place when loosening the last bolt so it doesn't fall to the ground. Inside the unit is a small box held on by four bolts, this is the water pump, remove the four bolts and the gaskets (there are three gaskets two rubber gaskets which sandwich a metal gasket). The small turbine lookin thingy is the impeller. Remove the impeller inspect the casing and gaskets for cracks or damage. If the water pump housing is cracked or damaged replace it same with the gaskets. Install new impeller and repeat thes steps in reverse order to re-assemble.
First find your year model and aquire a impeller kit as it will have all the replacment parts needed. To change the impeller you need to remove the lower unit. Put the motor into forward gear and remove the bolts/nuts holding the lower unit to midsection. Note that there is usually one bolt under the trim tab, usually it a total of 6 mounting bolts/nuts or less depending on year model. Once bolts/nuts are removed, the lower unit will drop down. The pump housing will be right on the top of unit with drive shaft protruding thru it. The pump housing is removed, then the impeller can be removed from the shaft. Retain the flat key and reinstall it with the new impeller,gaskets and wear plate. Lube the housing with some petroluem jelly or white grease, while pushing housing down turn driveshaft clockwise to seat the impeller in housing then torque nuts to 100 inch pounds. Reassembly is the reverse but make sure you line up the shift splines.
Remove the 6 or so bolts that hold the lower unit onto the leg of the outboard. There is an access panel with 2 screws on it that you have to remove as well that allows you to disconnect the shifting rod. Remove the little panel and loosen ONE of the bolts on the coupler. Pull the lower unit off of the leg, and when you stand it straight up, you will see a cover with about 4 bolts on it. That's the water pump housing. unbolt it, remove and you will see the impeller inside. The only tricky part of re assembly is making sure you get the coupler lined up for the shifter.
The lower unit comes apart the same as if it had a prop. The water pump is in the same location as the standard lower unit prop assembly. The only difference on the jet is, you do not have to disconnect the shift lever, because it is not used on the inside of the lower unit. Remove the shift cable on the outside of the pump unit. Remove the bolts on the upper part of the jet pump that connects the unit to the mid portion of the lower section. The pump unit is then removed from the motor along with the pump drive shaft as one unit. The pump housing is located on the top of the pump unit. Unbolt the pump housing from the lower unit and slide the housing and impeller off the shaft. Be careful not to lose the key that secures the impeller to the shaft (if used). Most kits include a new key, lower plate, housing and impeller. Be sure to fold the rubber impeller in the same direction as the original impeller. It is a good practice to apply a small amount of rubber safe lubricant to the housing when the impeller is installed to prevent a "dry fire" of the impeller when first started. Assembly is just the opposite of the removal.
