1971 9.5 Johnson..new impellor no water!

Re: 1971 9.5 Johnson..new impellor no water!

I poured some water in to the thermo housing, and it all came out around the plate that the shift rod and copper pickup tube come through. So I decide to take the plate off to replace the gasket, two screws came out one broke off Will the copper tube just pull out, or will I have to get the shirt rod out first, and if so how does the shift rod come off?

wind knot <br /> very interesting . How did you change the water pump with out getting the drive shaft out? it is impossible

Sorry not impossible forgot we are talking a 7.5 but would be very hard to do. Did you disconnect shift shaft?

So here's the new questions.<br />1)Does the copper pickup tube just pull out?.<br />2)Do I need to get the upper shift rod out, so I can get the plate and gasket out, that the shift rod and copper pipe run through?.<br /><br />Thanx in advance, Darrell<br /><br />P.S Wayne did you get my e-mail?

My POINT of replying to this thread is to try to help you. no the copper tube won't just pull out. You must remove the powerhead to get it out. <br /> Nickster

Thanx nickster. Sorry about the "point", but that was yesterday when I was choked at all the problems I'm running into, my apologies.

apollogy excepted<br /> To answer your other question about the shift rod. No the upper shift rod does not need to come out but I was curious wether or not that you had the 2 shift rods disconnected since you said that you could not get the unit to drop. Are you also leaving the water pump housing on when trying to pull the unit? Have you got the unit off yet? there could be a # of reasons why your motor is not pumping water. What kind of shape was your old impeller in? Was the veins broke? If they were there could be a piece of impeller under the water pump base There could be a piece in the copper tube. There could be dirt in trough the cooling system. The copper tube has a rubber grommet at the top of it. I've seen them get hot enough to melt that grommet and restict the hole. Even though that you could possibly blow air trough the tube doesn't meen that it doesn't have a restiction but before I would pull that powerhead try to get that unit off and inspect for dirt or other debree in the pick up.<br /><br /> Nickster

Knot....How is it going on the driveshaft removal???

Re: 1971 9.5 Johnson..new impellor no water!

Yeah nick the lower unit is off. The problem is, that the drive shaft stayed in the power head when I pulled the lower unit . I've tried to remove it but it's stuck big time!. My marine tech said that sometimes people put a super marine goop on the end of the shaft and jam it back in, if they had found on a previous impellor change, that the upper splines were worn. I don't know if this is the case but who know's. The old impellor was intact, and in hindsight I should have left it alone!.<br /><br />As for the copper tube, I'm going to try and get a hose to fit it, and run some water through. The problem will be, that there is'nt any room to tighten a hose clamp on it, so I need a tight fitting hose.<br />Thanks for the reply, Darrell

Re: 1971 9.5 Johnson..new impellor no water!

The problem with doing that with the hose is if the grommet on the top of the copper tube has melted but still has a small hole in it the water will pass trough. then you think everything is alright when it might not be. Also when your putting the unit back up on the midsection are you shure that you are getting the copper tube lined up with the water pump base. without pinching the rubber grommet in the water pump base. Is your pickup from the lake or test tank on the unit have any crud in it.<br /> Nickster

Xcusme, the shaft is still stuck. I tried the vise grip and hammer trick, but it didn't budge.<br /><br />Nick, the water intake passage is clean as a whistle, and so is my water barrel.

Re: 1971 9.5 Johnson..new impellor no water!

Wind Knot <br /> Did this motor pump water before changing the water pump? Did this motor ever over heat to your knowledge? Maybe try the hose thing. to reduce go with the fitting that xcusme shown on the end of your hose then put a smaller hose on it. you can also use compressed air to blow trough but not alot of psi going trough it. <br /> Nickster

Re: 1971 9.5 Johnson..new impellor no water!

Knot, it looks like that driveshaft has suffered some material displacement at the drive splines which is making it difficult to get apart. If you can't seem to get enough PB Blaster or other 'bust rust' solution right at the driveshaft/crank junction, it's time to pull the powerhead. You can inspect the water tube grommet while you have things apart. Be sure to grease only the splines upon re-assembly, that will go along way in preventing this from happening again.<br /> <br />BTW, you really don't need a hose clamp on the water tube end with the flushing rig I described ealier, just push enough hose up the water tube to effect a water tight seal and turn of the water.<br /><br />Good Luck.

Well I'm drinkin' a beer and doin' a jig! The motor's back together and pumping water!!!!!.<br />I got it back together with out pulling the drive shaft. <br /><br />Words can not discribe how happy I am, that one of our members at "Fish BC", suggested this forum. Thanks to all that replied to this thread. You guy's are great and I appreciate you taking the time, to help out a newbie to your board.<br />Darrell<br /><br />P.S I'm not done with this motor so BEWARE!. LOL
