- The Yamaha 200 horsepower outboard is almost 30 years old. IThe saltwater finally corroded a hole through the head and was leaking water into the combustion chamber. The salt waster seized the engine. It was a rust seize and so we were able to free it. We picked up a cheap pair of heads on eBay and now were back in business.

Nice bronco!
Have same thing my motor guy said it was electrolysis welded my
Thanks for the video! I had the exact same issue on opposing cylinder heads #3 & #4 with low compression 85-90 and water injection LOL through the head dome like yours
Either its from corrosion or bad castings from yamaha ?
Hi I am thinking to clean my pistons from carbon on my outboard? My question is do I have to put nex gasket after I done or can I use the same one after clean it? Do you also recommend this I mean should i give a good clean up to pistons or leave it like that? Thanks
Hello I'm working on the same motor do you know what the torque specs are for the head and the head cover. I was told it's two sets of tightening for each but cannot find the exact torque specs. I would appreciate any help thank you
Hey,,I have the same problem,,when I finish my we put the new seal and still leaking,,my question is if there is any type of sealing or filling the I can put after I put the seal on the head gasket..?.?.?
What did you use to remove the head bolts without breaking them? Need to do this but scared to break a bolt due to corrosion
How did you clean up the cylinders. I have a 1990 yamaha pro v 150. Had a similar issue. Seized up. Took the head off and found rust in 2 cylinders. Got the fly wheel freed up but it makes a loud squeek and get kinda hard in one spot while turning the fly wheel with a socket.
Hi. You need a workshop manual to build a 1980 hp 175 V Mercury engine (V6). Would you be so kind as to send it to me? From already thank you very much.
Hi I’m having same issue same exact situation, how did you get the piston free, well the flywheel, what did u do to get it to move
Would truly appreciate it 9:07
