    115 6c TOP piston cylinder issue

    I need a magnifying glass! They look like metal to me, but i can't imagine putting anything smaller in there, so either they are built in or are still there

    115 6c TOP piston cylinder issue

    Chris. The swivel pin is actually pretty smooth. I have kept the zirc fitting full and it actually feels good. Is it just the retaining ring to remove the pin? I looked through all the parts diagrams to look for rubber motor mounts. Are you referring to these: Mine are pretty toasted, if so...

    115 6c TOP piston cylinder issue

    Thanks! Those are really confusing! I can’t tell if there is anything in there or if mercury built it into the body. If there were inserts within these cavities, they were teeny!

    115 6c TOP piston cylinder issue

    I'm gonna look into the swivel pin and that area. I had to take the whole motor apart because the trim motor was completely corroded. I'm having to peel it off to try to salvage the pump, which i think is good. the lip at the top of the pump housing is a little nicked, but the orings and the...

    115 6c TOP piston cylinder issue

    If im correct, those would be beneath the balance and the bleed hose? I have the 3 screw in to left of carb and then the one that goes from c6 up to c1. I have no bleed restrictors in any of those cavities. I'm assuming they sit beneath the threaded inserts?

    115 6c TOP piston cylinder issue

    I wanted to give an update. I got block back from machinist. Though i would have liked to get actual measurements, he told me the current pistons would work well in the cylinders. The one nick i had(in cylinder 6) was beyond the compression chamber and he said was a non issue. I sourced all...

    115 6c TOP piston cylinder issue

    I am in the process of getting parts to rebuild. Ok stock on eBay, but the rings for the 3 ring pistons are expensive enough, and hard to find that it almost seems better to get new pistons. Is there any quality drop with the WSM parts? I am mostly finding old stock mercury, but there are a...

    115 6c TOP piston cylinder issue

    I get it. Hopefully I can find a good path through this. I don’t mind it not being perfect but taking it down to the pistons and cylinders, would be nice to have the motor running right. It is also crazy the price of motors these days. I live in the Seattle area and am convinced there is an...

    115 6c TOP piston cylinder issue

    Yes. I am getting new pistons, but I’m trying to get more into from the shop. I asked him to measure and bore if needed to next size. He ended up only honing them and when I reached out about them being possibly out of round they basically said they weren’t great and that I could either put it...

    115 6c TOP piston cylinder issue

    I have no experience with machinest, though the shop i intitially took it to that is an awesome mom and pop shop recommended him highly. He didn't rebore. He ended up only re-honing it. if there are questions i should ask him, let me know. i am a bit in over my head, or at least the first time...

    115 6c TOP piston cylinder issue

    I just got a call from machinist, and he did not have to bore at all. He was surprised, but the 2 cylinders with the missing rings cleaned up at .015. He did suggest replacing all the rings. The issue I'm having is that all of the existing pistons are the 3 ring pistons. I think this is the...

    115 6c TOP piston cylinder issue

    Yes. Ive been reading up on them. I read someone working on a rebuild that actually had an issue with new OEM mercury bolts. Does anyone have experience with the WSM road bolts?

    115 6c TOP piston cylinder issue

    Mine is a salt water motor too. I was honestly amazed to only have one stuck bolt in whole motor. I went really slow, used heat and lots of pb. I did break off 2-3 bolt heads on that section, but was able to get them off and out. Honestly, being in the salt is my biggest concern. I’d like to...

    115 6c TOP piston cylinder issue

    I do mean the head-waterjacket. Those bolts were so funky. Way worse than any of the bolts on the water jacket over the exhaust cover. I am learning tensile strength on those. I guess I’ll just go with the #5 steel 1/4”. My current plan, once I get the block back, is to try to reverse drill...

    What about those rod cap screws? Those are really expensive. I’ve heard that people tend to replace them when they get in crankcase

    115 6c TOP piston cylinder issue

    I have most of the pieces off. My head bolts were in terrible shape. I went really slow with lots of pb and heat but still have a broken bolt. This where I was considering stainless. All my water jacket and exhaust bolts came out. Planning on cleaning all threads and replacing bolts as needed...

    Do you use zinc plated grade 5? Is it a bad idea to use stainless with anti seize?

    I finally heard from machinist. I'll know more about what he's doing, but i know he can do it, so I am going to start planning out my process. Here is my plan so far. - rebuild water pump. I think its in ok shape, but if i did it, was a while ago. -clean carbs, check floats and needles...
