4 stroke outboards

I haven't worked on the new 200's yet, so I don't know about any oil cooler, as far as I know the 150's don't have a separate oil cooler, they do have a fuel cooler that runs vertically on the fuel rail that I've seen stopped up before. Ya'll may get a different version down under than we do. Yamaha has those small anodes all over the block, make sure you get new gaskets for them and clean the holes out go, I use Mercury perfect seal on the gaskets when i put them back together, if it leaks, it will be spraying salt all over your engine. if you are going that far, I'd recommend replacing the thermostat while your at it

The old 150 was already close to 170 at the prop according to several independant tests of teh 150, so I'm sure with some porting changes to the head, intake, exhaust, and a bigger throttle body that 200HP wouldn't be that much of a stretch.
