Thank you for sharing the idea of placing the parts on to the cardboard - excellent - I will put that knowledge to use on my current lower unit project. I have learned a tremendous amount from your content - Thank you for sharing your expertise !
In this engines , hone that cilínder and you could install only that piston oversized to .20 or .30 ,as long as the pistons weight the same you’ll be ok with only doing that cilinder…. Also make sure to gap those rings to that cilinder meeting the specs in that way you won’t be guessing the outcome.I used to be an omc mechanic trained in the factory …..I also done this and it comes out reliable.
I rebuilt an old john deere engine once and opted to bore one cylinder over 20 and leave the other 5 standard. The 20-over piston weighed like 16 grams more if my memory is correct. I took a die grinder to the top area of the connecting rod and took off 16 grams. After the engine was together it ran completely normal despite the larger displacement (in terms of power balance). But then again this was an engine turning 1300 rpm most of the time...
My last boat had a Johnson 90HP V4 very much like yours. It was cranky to start just like yours. Very interesting to see one being striped down and repaired. Nice job.
I have an old 1987 V4 90hp VRO Cross Flow? (I think) with all new parts, rebored, honed, and ready to reassemble. Been sitting in 25 boxes under my bench for a few years now waiting. I'm going to get at it soon. These videos are excellent confidence builders!! Thank you for sharing.
Many thanks for the rebuild video. I was glad about the overall result on rebuilding my v4 crossflow but getting accurate information for certain things not answered in factory service manual was a royal pain in the neck. I think a 3/4" brass barbed fitting that you can get at Home Depot/Lowes works well as a piston wrist pin clip installer tool on those pistons. It's possible to get the OEM clips without that tool, it is a NIGHTMARE on those Wiseco pistons for the wrist pin clips. That connecting rod tool I wish was a 1/4 of the price. Had to align the rod caps using a pick or throw away the used rods that wouldn't line up because I didn't have the tool to compress the ends to align.
Really like that ring test with the light to see the gap, was was thinking ah just chuck a new piston in it and send it until you did that. P.s where’s the cash tote gone?! That used to make me chuckle seeing dollars thrown into that
As an old retired mechanic it is very interesting to me to see the insides of one of these big 2-strokes. I've always wondered how they did the big end of the connecting rod where it was not one piece with a built up crank. With the huge number of 2-stroke 4's and 6's in outboards, I would like to see one modified to run in a motorcycle or maybe a jet ski
Nice job! Above my pay grade but have a 78 Evinrude 115 that hasn’t been started in 10 years. Will check the compression and if bad will just trash it cause boat is not that good either.
I have a 95 115 that I’m rebuilding. Lost all my videos of the disassembly when phone was lost. This video is a life saver. Need additional video on shifting cables and shifter set up… wonder if I joined the patron would you be willing to to do that?
Enjoyed that. We had some self-imposed rebuild rules in our shop.......... If it scored a cylinder wall and/or rolled a ring, we would always replace the thermostats, the water pump, and rebuild the carbs as part of the rebuild job. We also replaced the fuel pump. We didn't want a hot running engine and we didn't want a lean running engine. We were making an extra effort to eliminate what caused the problem to begin with. And, of course, we always checked to see if the heads got warped. More often than not, we planed the heads as a result. You usually never know what caused it. Ran hot? Why? Ran lean? Why? Total timing - is the stop adjustment loose? On and on........... Thanks for the video.
highly recommend using an engine or powerhead stand when installing pistons into a v4 or v6 crossflow. its not easy getting them in straight on a bench, and the block needs to be tilted to get it parallel. takes 5x longer and you end up dragging the rod over the fresh cylinder bores as demonstrated.
where are you located i would love to pick your brain about a 1980 85 HP evinrude i have btw great videos you are the only one i want to get info from about my outboards !
I had to laugh at the coffee can thing. I still use one but for 10hp or smaller motors. Now that time is a factor with more motors to restore going to organize them so I can pick it up.
Enjoyed the video. I have rebuilt automotive engines and I’m curious. What purpose does that tool serve when installing the connecting rod caps? Can you install them without the tool? It looks really expensive. New subscriber. Thanks for the video.
The bubble back exhaust parts...are they compatible with the flat back engine blocks? I have a 100XP that's getting low on compression and these parts seem a no brainer to add while in there.
Good video Brandon. What did the final tally of parts and repairs cost you? Got a couple 1980's 115hp that i want to hone and put new rings into.Can you do a video of the settings, linkage and sync, timing?
Great video I could change the spark plugs and maybe rebuild the carbs so I’m definitely not going to be a keyboard mechanic and point out what you are doing wrong 😅
Just a quick question if you don’t mind. How on Gods green earth do you keep up with all the nuts and bolts bolts and all the washers cotter pins etc?! Lol
What is the function of the bypass covers? I have had an engine block cracked on the outside of the bypass housing. Any ideas what may have caused this? Thanks again for a great video.
I've always been thinking that V-4 engines aren't best part of OMC outboards.( Unfortunately) this video didn't change my mind, althought Brandon made this job look so easy. Btw... My vintage Kawasaki outboard motor is a runner now😊, after sleeping some decades.
So I have a 1989 110 Johnson 2 stroke that came with a vro pump, and I replaced it with a regular aftermarket fuel pump, but do I need to remove the pulse limiter inline valve thingy?
Brandon, I am 79 to start with and just did what you did on a 1986 88hp SPL. This was new to me but after the rebuild, I am getting some hiccups and the idle screw is not coming back all the way even after Blaster and cleaning foam. I was thinking of adding a spring to bring the screw back to the stop for a better idle. What could be causing the infrequent hiccups on the hose water feed? jim

I have a 81 Johnson 115 seahorse and having trouble getting it running idk if my fuel lines are not right so you have a diagram to see where they run or if you could help me I can give you my contact information
From what I could see in the video, I probably would have just honed the cylinder wall, slapped in a new piston and rings and called it a day. Although I do have my own Kwik-Way boring bar, it takes all day to bore a cylinder because I only use it every couple of years for motorcycle restorations and I have to learn it all over again and its EASY to make a mistake.
Its not hard, but its easy to mess up. I have had a couple throw away cylinders because I don't use the boring bar enough. Not a good thing when boring cylinders on vintage engines! You can find these for just over $1000. I paid $3K for mine and it has not been cost effective as I don't use it often. But if you use one about once a month, it would be well worth it because you can do the job in a few hours once you familiarize yourself with it. Same with doing my own valve jobs.
I got 1987 I will try to do one cilynder I have not done any like that before so my question is what dice should I order in Amazon hope you read my message- thanks for the video
@@k.whiking4372Not required on the old outboards I work on. I'd be a little surprised that it would matter much on a 2-stroke since, unlike a 4-stroke, the rod is always in compression.

I can’t tell you how many engines I’ve rebuilt in my 38+ years of wrenching but that’s gotta be the fastest rebuild I’ve ever seen 😂😂 Glad to see you used a torque wrench 😂😂 An other great job 👍🏻
Hello sir! I’m looking to upgrade the motor on my 17’ bass tracker. Currently it has a Johnson 40hp. So you happen to have anything larger and preferably with trim. What’s the best way to get ahold of you? Thanks!!
More good info to add to my knowledge bank when I inevitably have to do this. Shame you couldn't find a machine shop locally. Frustrating living here and never being able to find local businesses to do stuff.
i thought it was only the 140 hp that had the extra manifold between the cylinders the 115 hp engines i have seen only had a flat plate not the ball that contains the manifold
I just gotta say! I could not have done this at all, i like that someone is this level of skilled, it is kinda satisfying. But i would fuck this up so badly, it couldn't even be fixed after i had touched it. And i was actually about to do this on my own. Its the same only 110 but, hell. I am just gonna slap on the gasket i tore up and screw it right back up. Hell i ain't capable of this kind ogæf delicacy. I want to, but i know my limits. And they are just about an inch over the ground. Im still in kindergarten mechanics. And i dont think i will pass from here, but hey i can almost talk to someone who knows what he is doing and he maybe just maybe he'd believe i know what im talking about, i dont even know what I'm talking about now😂
Months. I started it just before summer. Ron's wife fell ill, so he was a little delayed being able to accept the powerhead, then delays on parts, then I got busy with customer projects; and the delays just kept coming. I forgot to order spark plugs, and that delayed the video another week,
VRO = Variable Ratio Oil. It mixes the oil & fuel together before sending it to the carburetors. At idle it mixes at between 150:1 & 100:1 ratio depending on years to prevent fouled plugs from excess idling. WOT it would mix around 50:1 ratio.
Money. $120ish for each cylinder + $100 for the piston. Good way to save $660 + tax on a low hour engine within spec. Now, granted, it might be a little cheaper than that; I did buy new rings, and I did pay for the honing, so it's probably closer to a $500 savings.
I ran 100 hp commercial model evinrudes before honda 4 stroke took over the commercial crabbing industry after around 1000 hours on evinrudes they were junk & it was always the same issue rings sticking & this is what I could not understand why wouldn't they engineer a better design they knew exactly where their engines would fail & never made improvements also that primer injection gadget is a worthless pos

Ron from Rons Marine believes the prop was too small.

What did deleting the pulse limiter do? I have a 91 115 with the VRO deleted and have the same blue pulse limiter running the pump.

I was an OMC tech from 74-86. When did the 115 get the bubble back? Used to be only the 135 and 140
In 85 or 86 they changed from crank HP to prop HP. So the 140 became the 115 and the 115 became the 90. So this is similar to the old 140

Why would you only bore 1 cylinder over and not all 4 never have I seen that and I've built dozens of motors
Money. $120ish for each cylinder + $100 for the piston. Good way to save $660 + tax on a low hour engine within spec.
Now, granted, it might be a little cheaper than that; I did buy new rings, and I did pay for the honing, so it's probably closer to a $500 savings.
But it throws the balance out that 1 piston weighs more and will put more vibration in the motor it will eventually break again
