    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...

    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.

    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.

      Ron from Rons Marine believes the prop was too small.
      Which isn't a bad guess as it came with a pretty small aftermarket 4 blade.

    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.

    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

    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.

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

      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.

      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 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😂
