Lower Unit Removal on Johnson 225

[Blue_Runner]

Be very carefull not to muck up those threads. Not very hard to do.

I had one disobey me one time. I ended up taking it to the shop and they got it off but did not tell me how.

One last question before I proceed with my plan on trying to remove the lower unit. I was thinking about drilling a 11/16" hole in the center part of the engine up torwards the top where it meets up with the actual powerhead section so that I could see the driveshaft and hopefully be able to get some penetrant on the splines. I will lower the nose of the trailer to the ground and tilt the motor all the way up to help. My question is what is normally behind that section or is it just hollow? I can come back later and put threads in that and just put a bolt in it when I am through to plug the hole I made, I just want to try and get something on those splines before I start with the bolts. Your thoughts as they are always appreciated and helpful.

I wouldn't drill up there as you will dril lthrough the exhaust tuner. And if you do that you will have ALOT of work ahead of you as you will have to pull the powerhead, get the rusted and corroded mounts apart and then pull the powerhead adapter off to repair your exhaust tuner.

do you have any suggestions as to how I could lube up the splines to try and seperate it? I am out of ideas as to how to do that...

I would take motor off boat, hang upside down, and then spray the shaft it will run down to the splines. But like I have said I got rid of a motor just for this reason!

Wish you Luck!!!

even if you were to spray the shaft, your still fighting gravity, mj's right. pull the four bolts cables & harness and flip it. or bolt it back up, enjoy the rest of the season and get on it this winter.

I am going to have to third what MJ said. You can get alot more leverage by hanging the motor upside down and with wedges.

You had me so paranoid about the lower unit on my Merc being froze up that, at 11:00 last night I was loosening the bolts and dropping it a half inch. I couldnt' sleep until I found out if it was stuck or not.
