    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...

    115 6c TOP piston cylinder issue

    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...

    115 6c TOP piston cylinder issue

    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...

    115 6c TOP piston cylinder issue

    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...

    115 6c TOP piston cylinder issue

    It seems so. The trick is finding someone who knows how to do it and will take it on. I followed every lead I could find and they were all dead ends. And I live in the seattle/tacoma area, so I thought it would be easier. Waiting to hear if the machinest’s buddy can do it

    115 6c TOP piston cylinder issue

    I got to machine shop and the guy couldn’t bore a blind cylinder. He felt bad(I drove 2 hours to get there) and is gonna reach out to another machine at he thinks can do it. It’s wild that this is so hard to find. Anyway.. Will post when I find anything out

    115 6c TOP piston cylinder issue

    I made a valiant effort to measure the bores but I just don’t have the right equipment. I’m taking it to a shop to measure and recommend a course of action. The only cylinder damage I can see is a small scrape in 6, but I can’t tell what has happened beyond that. I think 1,3, and 6 are all .015...
