    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?

    115 6c TOP piston cylinder issue

    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...

    Thanks for the additional details on what it does. Ive got a lot of work to do, but will do this after i go through the carbs

    115 6c TOP piston cylinder issue

    That is interesting! i never knew what those little hoses were for. I figured it was part of some deep black art I wasn't meant to know. Ive only been using non ethanol gas, so I would imagine that makes the particular effect at least a little less pronounced. I was also thinking you could put...

    Good news! sound someone who can do it. I'm assuming he is gonna try for .03 on 3 and 6, but will wait to talk to him when he has block in hand. Will update as i know

    115 6c TOP piston cylinder issue

    Thanks. I’m trying to set up a path to not just fix it(assuming I can get someone to rebore) but also to be aware of possible issues. I bought the motor about 7 years ago, but it did not have a repair history. I am thinking that 1,3, and 6 have been rebored because they are all .015s. I...

    115 6c TOP piston cylinder issue

    Waiting to hear from the machinest. Ive been going through pieces of the engine I have here. The reedvalves facing cylinder 3 were a little out of spec. There were a couple of petals that were probably .009 or .01. Im trying to understand things that could have contributed to losing the...
