Nice to see major rebuild videos. I understand for some years and models it does not make financial sense to do major rebuilds, even for demonstration purposes. Not just because of cost, but mainly because of certain key parts are longer available. Might I suggest the following because there are tons of them out there, including mine: 1980's to 1998 OMC V4 90 degree crossflow (90 hp to 115 hp). Major rebuild, ignition diagnosing, fuel delivery diagnosing, VRO oiling testing/diagnosing, and possibly cover gearcase re-assembly (bearings/seals) Keep the videos coming, I'm sure there will be more things in the near future I will be buying from Boats.net and Partzilla.
I think a great suggestion would be how do you keep all the parts organized as you strip down the motor, there are so many numerous parts that would need to be put in some kind of succession when you rebuild the motor after taking it competely apart.
these engines are non-interference engines, so you can do whatever you want with the camshafts without risking damage. it says so in the very first pages of the workshop manual. -yamaha-tech
Hey John , I have 2005 F225 , the bottom port cylinder has a spark plug with nothing left on the end all gone . I launched my boat warmed up the engine for 15 minutes, , switched it off just to be sure of a restart, and nothing would turn over . Took the boat home , I needed the breaker bar on the spark plug , the engine still won’t turn over with all the plugs removed . Do you think my engine has any chance of a piston replacement. Thank you Eric
