Yamaha 9.9 Head Removal, Gasket replacement. 4 stroke, long shaft sailboat motor. Plugged with salt.

Today I remove the cylinder head and replace the head gasket on a Yamaha 9.9 outboard motor. The motor was full of salt from running in ocean waters.

Hey have you heard if removing the head bolts can be risky? Do they ever snap at the block? I have a blocked and cracked exhaust cooling port and would like to remove it and weld / repair, but could also run it till it blows.

[@carlmauro4813]

It should come right apart.

Hi. Great video! I have exactly the same problem on a 2000 T9.9. Looks identical. Approximately how many hours do you have into the head removal and clean out? Did you use anything other than a pick to clean out the crud?

[@carlmauro4813]

If wasn't making a video and the tool chest was nearby I could have cleaned it up and had it running in under 3 hours. I used the pick mostly but also a thin screwdriver, putty knife, and a round wire brush. I lightly brushed the head with a flat file. Order ALL the gaskets ahead of time. No oil at all on the head gasket and surfaces.

Hi, I'm doing the same job. can you tell me the tightening torques of the engine head. Thanks

[@carlmauro4813]

Oh I'm sorry. I looked them up someplace and I don't remember.

Hi good video, quick question, I’m doing the same with my Yamaha 9.9 minute 14:44, right next to the spark plug cable that water jackets how deep is it ? 1 inch/ 2 inch ? mine has a layer of salt and it’s rock solid, thanks

[@carlmauro4813]

Probably more like 2". The small ports are the water jackets. The black area is an exhaust port. You can see better at 9:45. The ports go all the way to the cylinder and all the way around to the other side. I put about 15 hours on the motor while on vacation at the Cape. Never missed a beat. Then I ran it in a barrel of fresh water for over an hour.
