Welcome to iboats.

If you have mechanical ability, and a few tools, it is not hard to replace a water pump. You should be able to replace the water pump and get a manual for under $100.00... I do strongly recommend getting a factory repair and service manual like this one for a good price on ebay. http://cgi.ebay.com/ebaymotors/1977...4859687QQptZBoatQ5fPartsQ5fAccessoriesQ5fGear

Be sure to ask any questions that you have. There are many here that will help.

yeah mate i am basicaly a motor machenic (cars) but when it comes to being off shore with my kids i want to know if the weather turns, my outboard will start... then i start the motor it sends a very small amount of water up (litteraly a drop comes out oe peehole every 2 secs) is there anything i shouldcheck before just replacing the impeller?

Being that the motor is a 1977, the water pump is probably real old. The rubber degrades from the effects of time and wear. I rekit my water pumps every 3 years.

Another thing to do is push some weed eater string up the peehole and make sure it is cleared out.

^^^ I would seriously consider this factory service manual on ebay. That's a great price. Also, buy the OEM water pump kit. It comes complete with instructions as well.

ok i have just "aquired" a manual, now i guess its time to buy the OEM water pump kit. where do i get one? is this site good for parts?

 

[woodys johno]

Re: need help asap. 1977 johnson 35hp probs

so in the kit do i get 2xgaskets, a impeller plate, impeller, impeller cup, and grommit? and am i right in saying it all slides over the drive shaft?

Yep and don't forget the impeller key, driveshaft o-ring and lube the splines.

Well guess what? i poked around with the whipper snipper cord into the pisshole and its now pumping better then it ever did.... thays an awsome relief phew but still got a problem.. the elec start is just going click when i turn the key.. is this solenoid or starter motor? its a simple click everytime the key is turned.. battery is full of charge and termanels are clean and tight

 

[glengold]

Re: need help asap. 1977 johnson 35hp probs

if the solenoid clicks and the starter motor doesn't engage its probably the starter motor. I'd use a test light to make sure the solenoid is supplying power to the starter motor when you turn the key. If the solenoid is bad you can still jump past the solenoid with a pair of INSULATED pliers to start the motor.

Re: need help asap. 1977 johnson 35hp probs

ok the solinoid is sending power to the starter but thats where the train stops... so i need new starer? or do i just do bushes etc? model number is 35EL77C

Re: need help asap. 1977 johnson 35hp probs

Your best bet would be to either rebuild it yourself or have it rebuilt. Every starter I've ever had rebuilt was under $50 and lasted forever. I wish I could do it myself

Did you measure ~12v at the starter terminal to ground?

 

[woodys johno]

Re: need help asap. 1977 johnson 35hp probs

NAH I DONT HAVE A METER TO READ VOLTS BUT TESTED WITH TEST LIGHT... sorry bout caps lock... um so the starter rebuild is cheap and more reliable eh? sounds the go... will any marine auto place do this? or should it go to an auto elec? what i mean is who would do the better job...

Re: need help asap. 1977 johnson 35hp probs

If your battery is 3years old or older, it may not deliver the cranking amperage that it should. Bring it to auto parts store and have them test it. (this is usually a free service) Your starter may not be the problem.
