Good day fellers,<br /><br />1972 100hp Johnson, Hydro electric shift.<br />Maiden voyage for the season. Leaving the house, and thought "i guess i might as well grab that extra impellar just incase." Launched, cruised 10 minutes, siren. crippled her back, no manual, but have read the impellar chapter about 20 times. LU dropped like a champ, taped a speaker wire to the shift wires, and sprayed them with WD40. Wires fished down very easy!! Clean up housing, installed new impelar with a little motor oil, to help spin into the housing. All of this at the campsite with a 20 dollar tool set.<br /><br />O.K. so here are the actual questions- replaced the O ring at the top of the drive shaft, cleaned everything very well. rubber thing that sits on top of the pump housing was in pretty sad shape but left anyways. I did not have a tourque wrench. using a 6 or 7 inch open end wrench i tightend the pump housing bolts until they were very tight, but not white knuckled grunting tight.<br />I did not have any marine grease with me, so lubracated the drive shaft with Penzoil 10-40 motor oil before sliding it back in. water tubes were in great shape, and fit back together tightly. Got LU back into place, and re-installed bolts. cleaned threads really well, and lubed with WD. I used again a six or seven inch open ended wrench, and got all of these bolts essentially as tight as i possibly could with this short amount of leverage. there was a part of that was nervous they were too tight, but i figuered with 100hp on 5 bolts that i better lean into them.<br /><br />So the questions are-<br />Can you get the LU bolts too tight with a 6 inch wrench?<br />is motor oil o.k. to lube the shaft when you dont have grease?<br />Should I be worried about this? There was still alot of heavy grease inside the female part of the splines.<br /><br />We ran the boat all over the lake that day, and you could put your hand on the cylinders almost forever and not get burnt, so i know this thing is working great.<br /><br />Moral of the story for us Hydro Electric guys? It really isnt that hard!! I have read so many forums, and talked to people are scared to death of these things, but it really wasnt bad at all! Even if you lost the shift wires completely, you could pull them all the way out, drop a fish wire down, tape em together and pull back through. Just use WD on the wire, and it is cake. I taped the wires end to end with duct tape, instead of overlapping them, so it wasnt too bulky to fish down through the hole.<br /><br />Thanks for any help. Hopefully this can be one of those, "if i can do it, you can do it" type stories for another electric shift owner.<br /><br />see ya,<br />J
