What’s the old fashioned way? LolI do my own boring the old fashioned way.------But I saw a video of a machine that quickly locates the bore and does this work FAST.----But that shop may still charge $100 / hole to help pay for this machine.
$30-$60ish a hole depending where you are.Yeah that’s what I was originally thinking... but what about the cylinders, just get them bored and run oversized pistons? Any estimate of how much machine shops usually charge to bore out the cylinders?
Probably have the boat for the next 2-3 seasons$30-$60ish a hole depending where you are.
You probably won't need the main crank bearings unless you can tell they're smoked. They're pretty stout bearings..... I was stating them for price comparison....
How long are you planning on keeping it??
Who is to say the three "good" holes need boring? If you're not going to keep it long I'd just get one bored and three good hone jobs assuming tolerances aren't too far off on the three. I honed all four on mine. My damage wasn't as deep and ring end gap is a little over factory but it runs great and if it's lasts me a year or two then blows up I'm good with that. Some will scoff at this but my budget and the fact that I don't fish off-shore is what guides my decisions.
For kits powerhead express seems cool but I've never used them. Just google and shop. I'd stay away from auction sites those.
My guess is the ring material was expelled through the exhaust. I haven't heard of any rings breaking so small that they got into crank and rod bearings. Seasoned vets may have seen otherwise.Also,
Looking ahead, all other pistons and cylinders look good. The affected cylinder only has two vertical scores, one I can barely feel with my finger nail, the other is more noticeable.
my thought is, can I get away with honing out the cylinder a little bit and then just get a replacement piston (original size) and skip the boring?
The only other damage seen inside the cylinder is a small chip taken out of the edge of the exhaust port.
You do not go by looks but by measurement's...mike the cylinder to see if worn past their limits or ports.Looking ahead, all other pistons and cylinders look good.
Why??? If cylinder is worn (which 90% are) do you want to hone and make looser? Measure and repair correctlycan I get away with honing out the cylinder a little bit and then just get a replacement piston (original size) and skip the boring?
Yeah. Even counted the splines lol. Took a couple tries. I have called the manufacturer (OBR) and left a message so I’ll see what they say come Monday. Workaround, I assume, probably entails modifying the driveshaft?The spline is the same count and size.-------The length of spline and sealing arrangement is different.-----Your local expert shops can help you with a " work around "------It is not the end of the world.
