Hi, I'm new to the forums and looking to broaden my knowledge on a used boat I picked up today I found online surprisingly at my soon to be 9th Grade son's former 8th grade teachers house. Her husband died 3 yrs ago and I don't think the son or her has cared for it as well as it needed to be.

Other than boating from 80-89 with the family when I was growing up I am mechanically inclined and have read the manual on the lower unit. The lady had given us a repair manual her husband had had, it's a Seloc Johnson/Evinrude Outboards Repair Manual covering the years from 90-95.
She initially told me that the motor was a 89 but through searching on the Evinrude site I saw that this model number was a 90 unless there's something I'm missing.

Came back to the campground and there were a few boat owners checking it out. We got looking at the lower drive and it was creamy and the guys said it's got water in it based on their exp. We removed the upper plug as we noticed it was leaking a little bit. The plastic washer was cracked and the bolt was a allen head bolt which is stainless steel. To make matters worse the threads are stripped out on the hole where the screw goes in. It just wouldn't stop turning by hand so I put the brakes on and I as well as my wife are nervous.

The boat is a Northwood 160 Pacer. It's a 1992 model. The trailer is a 1999 Shore Land'r trailer in great condition minus the right fender that was recently damaged which also damaged the tire from rubbing on the bracket when whoever hit it in the past. I paid $2450 and it had 10 gal of gas in it because uit's a 12 gal tank and I put 2 gal in along with 2 cycle 50:1 oil when I gassed up today. It also came with a 2 and 1 person tube and 4 used lifevests, 1 flotation device and a couple homemade concrete anchors along with some other misc stuff, tools, fairly new battery, etc. Overall I think or at least thought I got a good deal.

Can I find a good lower unit housing and put a bearing kit in it fro teh stripped thread or is there a alternative to that? My main worry though is what do I need to do to ensure this unit isn't shot and to keep me moving? I don't want a new motor, or a really expensive job at a shop. I have me, my buddy and one of his friends albeit a younger kid who works part time at a marine shop here in So. Dakota.

ANy help would be greatly appreciated big time as in parts sources, web links, tips, tricks, guides, winterizing tips, tutorials, etc. I guess you'd call me a Newbie but I'm willing to jump right in. Thanks in advance to all who respond


Sorry about being so long winded but I am excited but nervous at the same time.....

Sounds like maby not the correct screw as mine takes a flat head. How are the threads on the screw? Can you see the threads stripped out in the lower unit? That might be why water was in there. Check the prop shaft for play.

My LU oil was very milky I changed the gear oil & went out once. it sat in the water for 12hr, then in a full barrel of water for a week. It was not as milky when I change it again this morning. I dont know if more got in I am hopeing it was just residue. --- With no gear oil in it. I can feel a little movement (I dont like the play) but when it is full of gear oil you almost cant tell. If its like an automotive axle I think mine should be ok for now, I will monitor it closely.

I replaced the complete waterpump housing assy as the P.O. said it had been 12 yrs since he replaced it. Also a fuel pump as he said he replaced the rubbers inside of it & I had a feeling something was not right with it. (One of thoses little voices in my head... it was cracked & leaking when I double checked it).

Check out the Thread: Top Secret File UPDATED 8/1/2012 http://forums.iboats.com/showthread.php?t=299680
Lots of good info there. read...read....read...

Where are you located? I am on the mid east coast.

I understand the nervous thing BIG time. When we went out today 100' past the "NO WAKE" zone a BIG boat was haulin butt LOOKED LIKE OCEAN SURF WAVES. My oldest thought we were going to die, she was even in tears, but the little boat did good, I did not panic just turned into the waves some & worked the throttle to ride them out. I think them big boat guys like to do that crap! We had a blast.

I say figure a way to get the vent & fill pugs to seal up correctly & add fresh LU oil & see how it does. Just make sure the teltale is strong or replace the w/p. This site sells lots of parts. marine engines .com has a good parts dighram break down. Shows everything really well.

Re: Evinrude 48 Spl 1990? Model # E48ESLESA

I dumped the oil tonight, tried the drain plug in the top hole. Threading was stripped so I retapped it as I still have my tap and die set from the wrenching days I left in '97 but the threads are still a little loose. Most of what was drained was clear water at first then a small amount of oil, maybe 2 or 3 tablespoons.

I need to see what my next step is. DOn't want to buy a motor quite yet but a local trade for a different size motor may be in order if someone needs my size of engine but we'll see. Want to get a compression test done before I go any further with this given the lower unit issue.

I'm wondering if I should drop the lower end or not to make sure its not as worse as I'm thinking or even worse yet. Is this something that warrants it with all the water I had in it??

Re: Evinrude 48 Spl 1990? Model # E48ESLESA

Tok it out Mon afternoon after filling the oil and when under way and a load was being heavily applied to the motor a clunking noise like something is slipping was present. For the short time I was out the noise gradually got worse and worse. WHen I pulled the boat from the water and returned home the lower unit only had water in it and no fluid whatsoever this time around upon draining the fluid. The clunking noise was apparent but less when in reverse but not as heavy as a bang or clunk. It's almost as if something is spinning and then slips or whatever that the banging sound comes around.

ANy suggestions of where to look as the lower unit already needs to come off to figure out where the oil leak is so I might as well fix the clunking while I'm in there. Any other suggestions as to what else I can do while in there that one might just as well go ahead and do to save money in the long run? As stated in the first post I don't know much of the previous owner maintnence history so I'm kind of flying blind here. Thanks for any help in advance as what I find and suggestions will have me turning bolts in the garage.

Update on teardown.

This afternoon I managed to get the lower end dropped with my 14yr old son getting his hands all greased up with dad, that was good I must say as we have our differences in things we like to do mainly due to medical issues with my back and such.

Removed the shift rod, removed trim piece, removed bolt a little above trim piece and then removed the 4 bolts and lowerted the unit out of the way while keeping it straight. Alot easier than I thought this was going to be. I found the shift rod bushing on top of the housing had backed out from where it screws into the shift rod cover on top of the o-ring.

My question is if I screw this down, fill the lower unit with oil and reinstall the lower unit in the boat could this possibly solve my clunking issue with the lower unit when driving?

I tried rotating the driveshaft using a pair of vise grips in the middle and it rotates using the power of my hand though the propeller shaft donbt rotate unless I pull up on the shift linkage and rotate the drive shaft. I did get my camera with a light on it for looking in small places and was able to see the various shafts move internally when moving the 2 different shaft and while also pulling up on the shfit linkage and rotating the driveshaft the propeller shaft does spin.

I guess my question is could the cross pin on the sliding clutch be broken causing this issue? If so is this a big job being I have the lower unit removed? SHould I go in and remove the cross pin and clutch and see if that's the only issue and if so fix it and then refill it with oil and try that? I didn't see anything major regarding metal shavings in the drain plug when I pulled it yesterday after clunking around at the lake. Is the noise that I had going on a symptom of the sliding clutch?

How tight do I tighten down the shift rod bushing so i prevent it from coming loose in the future, should I use locktite or something different?

Is it recommended that I have the prop checked out or is it cheaoper to get another one new if i can figure out what I have? I was told the instaled prop was for more torque as opposed to a new prop they gave me which they said would be for more speed and recommended me to not use when I purchased the boat last Sat private party from the son of the previous owner who had passed 3 yrs ago. The son didn't seem to know as much as I thought as I'm finding out by just reading the manual myself which has helped me quite a bit. The manual hadn't even been opened before I used it as the condition showed.

If I take the remove the above mentioned parts will I need to replace the prop shaft oil seals, 2 of them and the bearing housing o-ring or can they be reused since there's no oil in the lower unit right now? Any and all help is appreciated.

Once again thanks for any replies to come and sorry for so many questions but I don't mind learning as that's why we all post here.

I thought I'd get some suggestions but I guess I was wrong.

with the lower unit off before you pull it apart - do a pressure test on the lower unit to find where it is leaking. soapy water in a spray bottle may be helpfull. If the case is cracked from being full of water & freezing then you will need another LU>

Re: Evinrude 48 Spl 1990? Model # E48ESLESA

I've come to find out that this is a Johnson lower unit repainted blue at some point along the way. OK top of the unit where the shift rod is there is a plastic nut that was not threaded all the way in which allowed the fluid to run out of the top of the unit. Being the issues I initially had, a bad slipping noise accompanied by. Intermittent bang I have started to do a teardown to be sure noting is wrong. I have the water pump Assy removed and need to go get some long threaded rod to remove the carrier bearing with the puller I have from when I worked on semi trucks. I guess the tool was meant to be kept around all these years (17) after I stopped working on them.
