How hard to install impeller

[tprice]

I picked up a new impeller for my 225 and looking at the directions it looks pretty simple. Is this anything for a novice mechanic to do. I will have the help of a friend that is a very good mechanic(rebuilds auto engines and etc for a hobby). He has a nice shop with work room, tools, etc. I have seen demonstrations of this on another web site and it seems pretty cut and dry but I am a little nervous about removing the lower unit of my motor.

Re: How hard to install impeller

I think the hardest part doing a water pump is geating the unit back up an extra set of hands really do help as far as droping the unit onces the bolts are removed(don't no about a suzuki outboard)don't forget the one bolt under the trim tab disconnect the linkage rubber hose for the speedometer pick up it should drop down.Next important step is the key way and the direction of the impeller fins when installing the new impeller.What I also found is to engauge the shift rod into gear so that you can turn the shaft to align the spline gears that would be it almost forgot a little coat of grease or oil in the housing will help so you wont get a dry start up good luck.

Don't forget to disconnect the shift rod. Here's where a manual is necessary because different models and year are connected differently. When installing the pump impeller, just lube it a little, and rotate it in the direction of engine rotation and it will curl right up into the housing. Then lower the housing with the installed impeller onto the drive shaft over the correctly aligned woodruff key and down to where it is bolted/screwed in to the proper torque. Or you can install the impeller on the driveshaft and woodruff key and then lower the housing down onto the impeller and rotate the housing in the OPPOSITE direction (which in effect rotates the stationary impeller in the direction of engine rotation) until the impeller curls up into the housing. The important thing is to get the impeller pointed in the direction it would go when running the engine. Also when installing the lower unit, lube the rubber grommet on the water tube that goes into the pump housing.

hello<br /> the hardest part about it is getting the old impeller drive key out. I use a cold chisel and place it at the top of the key against the shaft and drive the key down. it usually comes out fairly easily<br />good luck and a clymer manual will help more for that than a yammy one.

hello again<br /> one other thing. if this motor is approximatly 95 or newer it will have a drive shaft collar just above the impeller. the easist way I have found to remove this is to leave the stainless insert in place. use 2 screwdrivers 180 apart. place the tips between the plastic retainer and the steel coller and twist them so the plastic gets pushed down and the collar gets pushed up.<br /> then follow the manual to reassemble

tprice: I just replaced the impeller on My 2001 df115. lonewolf5347 is correct, the hardest part is getting it up and in. I tried something new this time. When I removed the lower unit I made sure not to rotate the drive shaft. I made a mark on the pump housing and another on the drive shaft with a yellow crayon.After removing the old impeller and installing the new one I turned the drive shaft back to the marks. It worked like a charm. Don,t forget to seal the bolts with silicone. Keep the silicone off the ends of the bolts or they will not tighten properly. Sometimes the lower unit will get stuck because of corrosion, be carefull not to hit it with a hammer, use a rubber malet, be gentle. The speedometer nipple and hose gave Me some grief getting back together. I finally weasled a right angle pliers up inside and pushed the hose over the nipple. I have pics of the lower unit innards but the make and model are different, won't be much help to you. Good Luck. You can do it!

my .02, if this is salt water motor, the bolts holding the housing could be a problem if seized!
