1972 9.5 hp Evinrude

[standfas]

Several questions - <br />I had this motor shipped to me with the lower unit removed. While trying to put the lower unit back on, it went a certain distance into the motor and wouldn't go any further. I took it back off and noticed the water line was loose. What should the first step for me be? Are there any other maintenance items I should do while the lower unit is removed. This is my first attempt at something like this and am looking for advice.

One other thing. If I decide to take the motor to a repair shop, how much does a tune-up on a motor like this normally run?

Stanfas, <br />The first thing would be to obtain a service manual and parts manual for your motor. You'll find all the info you need on proper assembly and maintenance of your motor. Some water tubes seem 'loose' and wobble a bit...it's normal, they have a rubber seal at the power head junction, some have compression connectors and will be more rigid. Lower unit inspection will include, drain and replace the fluid, look for water intrusion (lower unit lube will look milky if it has water in it). Replace the water pump impeller even thou it may look good, this way you know for sure how old it is. <br />The manual will walk you through a tune up.

Hiya,<br /><br />Unless you know that the water pump impeller is new, I'd replace that while the L.U. is off. It's the rubber piece inside the pump that actually pumps water. (it's on top of the LU, the driveshaft sticks up through the water pump). Investing in a service manual would be a good idea at this time. Even if you don't anticipate working on it yourself, at least you can read what's involved in doing something, and get an idea if a shop's quote seems way out of whack.<br /><br />Yes, if you weren't getting the water tube into the pump correctly, you could have a hard time pushing the LU up enough. Normally they are a bit loose, and you can wiggle it into the right place. <br /><br />As for tune up $$$... I dunno, of course it depends where you take it, and what they end up doing. When it comes to having someone work on an outboard, the tally can often be surprisingly expensive (expensive parts, & high shop rates)<br /><br />HTH<br /><br />Brent

Re: 1972 9.5 hp Evinrude

oops sorry i hit the wrong key. i think you just bought that engine from me i will ship you info on tune ups also on the motor i did not know you where part of this board.they are easy engines to work on and parts are usually instock at your local evinrude dealer.u need to change the water pump that engine has been sitting a number of years.it was going to be a parts engine for my 9.5 but i never had any big trouble with it and was tired of falling over the parts engine.the lower unit should slide right on make sure the shifter is in the right position. if you are looking to run the engine make sure you run it in a barrel or bucket you never wanna run the waterpump dry not even for a second.

Hey Wayne,<br /><br />I did buy the motor from you. When I inspected the water tube, it isn't connected to the power head. It pulls all the out. What should I do to re-connect it?

 

[standfas]

Re: 1972 9.5 hp Evinrude

Do I need any kind of gasket or sealer for the lower unit?

 

[wayne h]

Re: 1972 9.5 hp Evinrude

at the top of the power head the tube goes into a rubber grommet you should be able to get it back in there in so sealer that goes on the lower unit. it just bolts together. i am not sure if u can look up the houseing and see where the tube goes in. i do it by feel.

Re: 1972 9.5 hp Evinrude

A little grease or oil on the end of the tube will help it go in. Not much needed.

Re: 1972 9.5 hp Evinrude

When ilook up into the housing, all I can see is the hole for the drive shaft. Does the water tube to left or right, when looking from the rear of the motor, of the drive shaft hole? Thanks guys for all the help!

Re: 1972 9.5 hp Evinrude

Another thing I noticed today. There are two wires coming out of the "stop" button. One of them has broken loose. Will this keep me from getting fire?

 

[Xcusme]

Re: 1972 9.5 hp Evinrude

Standfas, the 2 wires goto the 'kill' or 'stop' button. One wire should go to ground, the other goes to the ignition. When you push the button , it's shorts the ignition to ground, effectively , killing the spark, and the motor stops. Having one of the wires disconnected will not allow you to stop the motor. Look to see if this wire went to a bolt on the power head, that would be the ground connection. You can stop the motor by pulling the choke ,if you had too.

Re: 1972 9.5 hp Evinrude

If I am understanding correctly, I don't need the two wires to be connected to run the motor. They only need to be connected to stop the motor when it's running. Is this correct?

 

[Xcusme]

Re: 1972 9.5 hp Evinrude

Yes, that is correct. As I said, you can pull out the choke to stop the motor.

Re: 1972 9.5 hp Evinrude

This may be pretty elementary but, when checking spark, do you take the plug out, reconnect to the plug wire and pull the crank? This should show spark on the plug, right?

Re: 1972 9.5 hp Evinrude

Hi Standfas,<br /> In order to check for spark, the wire has to be connected to the plug AND the metal body of the plug has to be grounded to the motor block.<br /> As for the water tube - I think you may be in trouble there. I had a 1970 9.5 that pulled the tube out when I pulled the unit to replace the impeller. I tried for 2 hours to slide it back up in there and I've been working on outboard for years! The water tube grommet wasn't visible from the base of the exhaust housing and I couldn't hit it by chance to save my life! Talk about frustration!<br /> I finally had to completely disassemble the mid-section, remove the powerhead and re-insert the tube in the grommet. A typically 1-hour job ended up taking two days! It's not difficult, just time consuming... Also, get a digital camera (or a Polaroid) and take pictures along the way, as it may help you get everything back together correctly...<br />- Scott
