1964 Evinrude 9.5

What's the best way to drop the lower unit to get access to the waterpump?? I took out the 4 bolts and pulled it but it doesn't separate enough to diconnect the shift rod. I put it in reverse but still can't get to it. Am I going about this all wrong?

If it's like my 77, once you pull down the lower unit a hair you then have to unscrew this pinch bolt on the shift rod.

Try shifting to Reverse on the motor. That my drop it a bit more.

Re: 1964 Evinrude 9.5

That's the thing.. I can't spread the gap large enough to get at the shift rod..

Re: 1964 Evinrude 9.5

Putting it in reverse only spreads it less than a 1/4 inch..

Re: 1964 Evinrude 9.5

it should drop down lower then that. u have to totally remove the pinch bolt from the bracket. also it does not drop down very far just enough to get a screw driver in there to remove the bolt

Re: 1964 Evinrude 9.5

Sawzaw. Nah, just kiddin'. You mentioned removing 4 bolts. Is there also a stud towards the front with a 1/2 inch head nut on it? Is it corroded?

Re: 1964 Evinrude 9.5

I can't recall if there is but if so, it would be located where the crack is towards the front where your gearcase meets the exhaust housing. Just under the lower motor mounts.

Re: 1964 Evinrude 9.5

Wayne when you say you have to totally remove the pinch bolt form the bracket I assume you mean the screw in the gap between the housings. Is there something under the cowl that needs to be loosened?<br /><br />I got the manual and I am doing what it says but no matter what I do I can't get ti spread wide enough to get a nut driver on the nut. If it was a screw I might have a fighting chance but it is a nut(no slot).<br /><br />I have doen water pumps before and this one is bugging me. I went out and looked it over agian and just cannot find why it is not spreading farther.<br /><br />Any further widsom would be great.

Re: 1964 Evinrude 9.5

Just lost a socket up there tonight. If this was a screw I would be fine. I just cannot get a nut driver or socket in it no matter how hard I wedge it apart. <br /><br />Is there any other tool I could use that would be slim enough to do this??<br /><br />I am stumped. Can I go at this from the bottom, meaning splitting the lower gearcase and allowing more slide that way??<br /><br />I have lost a socket in there so know I have to get it apart.<br /><br />Please any help..

Re: 1964 Evinrude 9.5

OK scrap that last. i got a nutdriver on the nut and loosened it. I worked the LU off with some effort. <br /><br />What happened is that the shaft did not come off the powerhead. I pulled out of the gearcase. It pulled the impeller key through the plastic pump body.<br /><br />My next question is how do I get the shaft out. <br /><br />I am guessing that the LU didn't drop because of the shaft not dropping.

Re: 1964 Evinrude 9.5

I kinnda thought you were heading in that direction, (stuck drive shaft). Try inverting the motor, spray PB blaster down shaft and let her soak for awhile. Using pliers on a non-bearing surface, turn the drive shaft back and forth to disengage the splines from the crank shaft. Depending on the amount of metal displacement on the splines, this may take some gentle persuasion. Be sure to apply grease to the splines only when you reassemble everything.

Re: 1964 Evinrude 9.5

Thanks I'll give it a whirl.. Is it usually rusted when they get stuck??

 

[Xcusme]

Re: 1964 Evinrude 9.5

Rusted? Usually..because the lack of grease has two effects. It allows the drive shaft and crank to rust and the drive shaft splines get displaced. Grease helps to diminish the effects of torque loading on the splines themselves. Dropping the lower unit to replace the impeller on a regular basis has it's rewards, along with the peace of mind knowing the powerhead isn't going to overheat. I guess the old addage, 'An ounce of prevention, is worth a pound of cure' applies ....

Re: 1964 Evinrude 9.5

This is a very new to me OB and am not sure when or if this job has been done before. FWIW, the impeller looked remarkably good, although it will be replaced..

Re: 1964 Evinrude 9.5

it dont matter what they look like they need to be changed every other season. good idea to change the thermostat with it also or at least check it. get a manual for that motor they sell them pretty cheap on ebay. i would stick with a factory manual they are way better and tell u more

 

[rogerwa]

Re: 1964 Evinrude 9.5

I was expecting to open it up and find bits and pieces. I am also doing the ignition, points etc.. I'll check the tstat when I get there..

Re: 1964 Evinrude 9.5

How long should I let this thing soak for. Shoudl it take a couple days and multiple dose of PBBlaster to soften it up?? Can I give it a few blows with the big hammer to loosen it??<br /><br />thanks..

Re: 1964 Evinrude 9.5

what are u hitting with a hammer ???? not the flywheel there is a puller for that DONT hit the crank with a hammer

 

[Xcusme]

Re: 1964 Evinrude 9.5

I wouldn't take the hammer to it. The pinion gear end of the drive shaft will suffer. As I said, invert the motor (flywheel on a towel), grab shaft with a pair of pliers (pad the jaws and not near where the water pump will be installed), and try turning the drive shaft counter-clockwise then clockwise, back and forth. With enough PB blaster, time, and patience, it should come free. It should lift straight up and out of the crankshaft.
