To my knowledge I haven't done any of that. But I've only owned it for the past few months. The outdrive had plenty of signs of misuse but was too be expected with an 18yr old boat. Guess I can chalk this up to previous owners neglect and me paying for their mistakes. Hopefully the problems end here.

I'm finding new complete SEI 116 outdrives for about $1600. Sound about right? That's not including install kits or zincs.

Sounds about right. I put one on a boat I owned 6 or 8 years ago. Decent drive, great warranty. Sure beats the OEM price. If you aren't in the ocean you hardly need anodes.

Be careful when you install. The paint is relatively thick and banging on it will chip it.

Generally I'm not in any saltwater but you never know.

I've ordered my parts and they should be in within a week or so. Been watching the install video from SEI and they use an alignment tool that I would hate to purchase for one use. Any thoughts on a work around? I'm not really sure I even know the purpose of it.

There is no 'work around' for engine alignment. You do it right, or risk destroying the coupler. The tool isn't that expensive, and if you continue to do your own maintenance, you'll be using it every year (checking alignment is part of the annual service)..

Gotcha. Ok. New to the I/O motors. Guess I'll get one of those too. Didn't know it was used that often.

The more I learn about the alignment and everything behind the outdrive the more I'm worried I damaged the part (can't think of it's name) attached to the flywheel that the yoke slips into. Is a visual inspection all I can do? Also should I replace the main bearing as well?

Coupler, yes visual inspection is about it. Need to pull the motor to change it out anyway, so it's not really a "while you're in there" kind of thing. Main bearing = gimbal bearing? No need to change unless it's worn. It should spin freely with no catching or grittiness.

If you damaged the coupler you will be able to see that damage through the gimbal bearing. Shine a flashlight and look.

Yes coupler and gimble bearing. Ok. Pulling the upper unit tonight. Still waiting on my new parts but wanting to get it ready to install and see if there are any other problems.

I know the coupler can't be replaced unless the motor is pulled so really hoping it looks good. I have a mind to change the gimble bearing or at least repack it with grease. Is that ok? Or am I asking for more trouble? If it spins freely should I just leave it? Is that service nipple on the side of the gimble housing used to grease that bearing?

Also I noticed there are several bolts and parts on the new outdrive that need to be greased upon assembly. Any special grease recommended? I have your standard marine grease...

Well I got my new outdrive assembled and installed. Filled it up with drive oil, put the prop on. Water hosed it and fired it up. Sounds great. But there's freaking water squirting out of the top plate! There was nothing in the assembly instructions about touching that top plate. I made sure the bolts were tight but it's still doing it. I know that's not right. What the hell!?

The upper has a passage that connects to the water coming from the pump. It has no seal or gasket at the top. Usually it leaks and dribbles for a while then stops. If it bothers you, and it shouldn't, the oring seal keeps the oil in and the water out of the bearing and gearcase up there, but if it does, you can pull the cover and seal up the pocket area and stop it dribbling. Personally I ignored it and it went away after a few days of usage.

Ok. Well that makes me feel better. Obviously I'll have to change the oil after breaking it in so I can check for the milky stuff. I'm going to leave it because I'm ready to boat! Y'all have been great. Appreciate the quick reply Rick. I was so excited and then it does that. While it was down I added a transom trim switch, fixed the trim sender and limiter that was broken, added a rear wired remote for the stereo. Ok. I'm taking it out tomorrow to putt around for the next 15 hours of use. Haha
