150 ocean pro lower unit removal

[crazy charlie]

I am taking off the lower unit of my 1995 150 ocean pro Evinrude to take to my mechanic for a reseal thursday.He told me there is just 1 screw under the carbs and just the bolts and skeg hex on the lower unit.Sounds as easy as removing an alpha drive.Am I missing something here????? Do I remove it while in neutral?? All pointers are welcome as I service my sterndrives but usually not the outboard so I am less familiar with it.Charlie

I think it is as easy as you describe, had mine off (though a different HP)to replace water pump and it was that easy, as long as it has been off before and the bolts come out, I do not think that there is a real lot of difference in a stern drive lower assy and an outboard.

If I'm not mistaken ,your engine model has the split type shift rod coupler under the carb area.If so,you'll need to remove the hitch pin from the shift arm and push in on the arm to separate the coupler.may be easier to also remove the shift cable from the link arm to afford more movement.In short,I don't think you need to remove any pin or bolt from the shift rod.Real hard to see under the carb area on most models.Removal of the intake silencer may provide a better view of the coupler.

Yes ob, the intake must come off ,you cant see a thing with it on and it comes off real easy.Solid rubber bungee type cords hold it on.I will get a close look at it tomorrow.Anyone know if it has to be in or out of gear while removing ??

In or out of gear, but don't unscrew the shift rod (will change the effective length. There's a bolt under the torque tab holding the LU, also.

I was concerned with messing up the adjustment on the shifter.

Re: 150 ocean pro lower unit removal

Easiest way to get to the shift linkage on your motor is to split the belly pan and pull off the port side. Even if your shift linkage releases by pushing the linkage from the other side its much aesier to get it back together when you can visualize whats going on down there.<br />If your mechanic does a complete re-seal then he will have to unscrew the shift rod and then screw it back in thru the new seal there. Question him on getting the shift rod height correct wghen he re-assembles it.

Charlie, I have a '95 200 and did a water pump back in August. I think it's the same as yours.... pretty much. The L/U comes off real easy. Make sure you don't miss the bolt hidden under the trim tab ( the zink lookin thing with a skeg on it just above the prop ). The shift lever disconnects by removing a shoulder bolt from the linkage under the carbs. Do yourself a favor and split the lower cowl on the motor. It's only 4 bolts. The port side comes off and you can see and access the shift linkage real easy. Just dont turn the shift rod while you're working on it and you'll be fine.

I edited my previous post too slow, Bruce there is a concern with the shift rod height after a reseal job

Thanks guys ,those were the pointers I was looking for.Should not be a problem now.

OOPs. Sorry Walker. I guess we were posting at the same time. I forgot this was a reseal and not just water pump. Charlie, Walker is the expert. I'm just a guy that has had a few successes by taking the advice offered by Walker and many others on this forum.

Took a pretty good look at it but didnt have the time to take it apart.Looks like the horizontal linkage rod just pushes out of the knuckle after it is loosened.The "shift rod that I dont want to turn is the rod that runs parallel to the drive shaft..??Is this correct??

Yes.The shift rod is vertical.What Walker is refering to I believe is that you don't want to rotate the shift rod during the lower unit service.You'll want to insure that its preset length remains the same.This lenghth can be changed by accidently turning because it is threaded on the end that attaches it to the lower unit internals.
