Reassembling the 2000 Yamaha f100 four stroke outboard. All I did was replace the crankshaft main journal bearings and a head gasket that was blown. I bought it from someone who ran the engine for 3 months after a shop rebuilt it. The guy said it overheated and had locked up. I bought it and opened it up to see what she looked like inside. Head gasket was blown and main bearing were toast. Everything else looked fine, kinda!

I still have to watch your video, too much going here even to sit down during the day. Glad to see you back on the engine. I have always enjoyed building Outboards.
Good video boss!
The fun begins
Watched the video..Wanna do mine boss???
After the next video, I'm not so sure you want me to do it! Talk to Rojo. :bashQuote:

Not sure if they dropped their love for a little more compression in the 4 strokes. Nobody runs Mercury engines here except Verado engines, they are pretty awesome supercharged and all.Quote:

Bummer. You’ll figure it out.
Yep, I still got a dilemma. One thing is, I think my compression tester does not seal well on that seemingly bad cylinder (number 2). I have a new compression tester on it's way.
Two, I fried the starter motor trying to diagnose things. Got another on the way too.
And three, it does run, just not so sure how well cause I could not keep it running.

There's a lot going on in that video. A lot of problems I'm uncovering as I go along. But yep, I still got a dilemma as it still don't go!

Here the one problem. Starter motor gears a little chewy.
