Where does the pancake bearing go? Didn't see it on the diagram but I may be mistaken Sent from my iPhone using Tapatalk

How do I reach this fella ? I will get the measurements for you tomorrow afternoon and see what I need from there. May try and find a head, carbs, and the correct domes after that Sent from my iPhone using Tapatalk

What's the best place to grab a set of carbs ? I messaged that NASS or whatever head place and haven't gotten a response so I may try another Sent from my iPhone using Tapatalk

Thanks man and will do. Yeah I woulda never bought this thing if I didn't think I could have handled the rebuild somewhat easily. I always spend the extra time or money on a motor to replace everything that way it's ready to roll but I may have made a mistake with not lapping the cylinders or head from the start Sent from my iPhone using Tapatalk

Yeah I was leaning towards the top of that cylinder being partially warped or the head. The only step I didn't take was lapping the head and cylinder before I put it together. Everything was torqued exactly like the manual said. Yeah I figured it was a metal-metal seal and the oring was just for insurance and to keep water out but man it's hard to imagine it ever would seal right with the jugs being separately bolted down and the head being one piece covering both jugs.

Well that's the deal. The left plug (good cyl) looked good. Dry light light black color. The right plug was black but the grounding electrode was burnt about half way back towards the side. Idk if that was from the water hitting it or what Sent from my iPhone using Tapatalk

I dabbed some sealant on the key way and around the bearing in the tranny like I've seen some of the videos I watched do. I really doubt it's going to be a problem w any of that - but I've been wrong before Sent from my iPhone using Tapatalk

Idk how long aluminum will last but you can give it a try. Most of the ones I've seen were teflon type material pressed in. I used bearing brass because I've got about a thousand lbs of it laying beside the lathe Sent from my iPhone using Tapatalk

When I was taking it apart ^^ Sent from my iPhone using Tapatalk

Primary gear appears to be factory. I may have another picture let me check Sent from my iPhone using Tapatalk

Yessir found some decent surprises while I was in there too Sent from my iPhone using Tapatalk

But the ones I took out were the high temp style red orings. New ones I received were black and I asked the fella about it and he said "well we use to use red but the black work just as good"........ now here we sit with a f'ed up brand new piston that left pecker tracks on my freshly bored/honed/ported cylinder 15 min later.

I was turning it pretty good when I heard the pop/spew sound it made when that oring let go. Engine quickly coasted back down to nothing and died. Would not start back. But the weird thing was - when I disassembled the engine the first go round - both orings around the cylinder domes were in perfect shape Sent from my iPhone using Tapatalk

Well I guess what I meant was - since I was already rebuilding it - I bought all new seals and gaskets, like I would normally do on a rebuilt. I don't reuse seals - ever. I just didn't imagine it would be a seal since there isn't any signs of fuel/oil leaking anywhere around any of the seals on the motor after looking closely at it right after she popped.

Oh if that's all there is to it - I'll order them from whoever on here or eBay has them. Just didn't want to get the run around on some little aluminum domes and also didn't want to wait a month to get parts back if all that needed to be done was a little degree change. I need some for the 66.5 mm bore too. Didn't know how hard that was to come by. But either way this dang thing is about to get on my nerves already. Just want to get it running longer than 15 min hahaha Sent from my iPhone using Tapatalk

You care to elaborate on that? I'm new to these little motors and I'll take any advice I can get. Motor died when that oring popped where you can see there Sent from my iPhone using Tapatalk

I can machine them if needed no problem. I'm not trying to win races I just want it to last at least a few runs more than it did the first time. Sent from my iPhone using Tapatalk

So this head ? Which domes ? Sent from my iPhone using Tapatalk

92 model - get on boats.net and order what you need. You can usually get away with ball honing those cast cylinders and slapping some pro-marine pistons back in, bearings (if needed) seals and some Loctite anaerobic gasket maker and torque everything back. One piece cranks so it's much easier. If I was going to guess I'd say $1000 or less Sent from my iPhone using Tapatalk

How old is it ? Sent from my iPhone using Tapatalk

Yeah those are easier for me because I've been running and playing with them for 25 years haha. My first banshee and so far it's been a little nightmare. Yeah it was ported when I got it - then ports cleaned up again a few weeks ago before I rebuilt it. I'll measure it and see what I come up with. I left the jetting the same in the 34mm carbs since we didn't really change much just cleaned it up and rebuilt it. Sent from my iPhone using Tapatalk

So with those pistons - which cool head would be the best to buy ? Which domes? And as far as ports - I was told they were ready to roll so that's why I put her back together. The port in the photo doesn't look good because it has aluminum growing on it. They looked great before I put it together - and the other sleeve/ports look fine. No scoring or compression loss whatsoever Sent from my iPhone using Tapatalk

Exactly why I asked yalls opinions haha - I knew I had something messed up. Outboards are much easier. Less porting - and easier to fix usually. This was my first go round and I'm still learning. $4-500 mistake but hey - at least there isn't a rod hanging out........yet Sent from my iPhone using Tapatalk

Well like I said. The original engine was ported and built by "OFR" whoever that is in CA. They put the head and pistons and domes in. All I did was sent it off to be bored, then rebuilt it thinking that wS all there was to it Sent from my iPhone using Tapatalk
