I did split rod bearings, cages, and caps, by piston. I am getting some real micrometers, and a decent dial bore guage. I'm going to go through the cylinders and get some numbers. This is too much work to just slap it together(Ive rebuilt everything but lower unit) and I want to make sure it is...

No! I appreciate the time and detail. This is all new to me. It is strange that it doesn’t talk about ring gap in the manual, but I’m going back through and measuring that now. I had about .006 at 1” and bottom in c2(standard). That was the one I broke the ring on, but again, think it was from...

Wow! Thanks for the details. This is all such an education. I wish I had that communication and detail from the machine shop. Honestly, I thought I wasn’t going to be able to get anyone to do the work and was gonna be sitting on a broken block. That said, I have very little detail on what was...

Ive never installed a piston in a cylinder, so lets start there! Do you have any thoughts on my question? I had compiled some notes on assembly. One person had mentioned checking end pin by turning the piston in the cylinder after it was installed. My question/concern was that i thought the...

Wow. That is a sensitive engine! I'm assuming you had it down at 650-700? I was told you had to keep your idle a little hotter. I am pretty good with the non-ethanol gas and using Marine stabil when its sitting, but here in the puget sound, with not many fuel docks, it is hard to be that on top...

quick question: I have built my pistons and started installing them. I had 4 of them in(waiting for rings for 2 pistons) and was checking through exhaust ports. All 4 seemed to have the same up and down feel, and the rings seemed tight in the ring lands. I had a note to check the ring stops to...

When i first got it I had never messed with a motor before, so everything, including adjusting the timing, is a bit suspect. I think i got it right, and i followed the manual..The engine ran well, but it was hard starting cold, and i had i set the idle screw a bit hot for it to idle well. I got...

My idle is a little high. When I first got the motor and was getting to know it I was told that was “just how it was” with old Mercs and the trade off was biting the gears a bit. I could never get it much below 950. My attitude is since it’s all apart, I should replace what I can. That stuff...

Interesting. I’ve been working on the crankshaft. It looks pretty good( cleaned up a bit of grit on one bearing-now smooth) and noticed the alternating 5 petal, 4 petal arrangement. Nothing mentions this. Is this something Mercury did? I have a couple of petals that are more than the...

I can see a retaining ring. It seems that to remove the upper bushings I could cut the nut and pull back but maybe the screw wouldn’t pull out. I’m realizing I’m probably gonna have to drill out the 5 bolts to the middle exhaust. They are so corroded and there is no way other than that to get...

I think I'm gonna replace them. I'm trying to figure out on the swivel bracket which parts I need to get that I can't get locally. Seems like just the two bushings. To get to the swivel pin, you just need to remove the retaining pin on the bottom?

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

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...

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!

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...

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?

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...

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...

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...
