Blown engine

[Pursuit2550]

So I was running around 53-5500rpms and suddenly I hear clack,clack,clack. I bring the engine down to idle and still doing it so i shut it off. I know its a rod knock, it was coming from the engine. I have been looking and found 2 99 Yamaha 150s fro 6000. Only thing is that the guy says they have 130psi on all cylinders. Isnt that to high for a 150. I have twin 93 150s so I will probablly repower with newer but used engines.

Re: Blown engine

No, actually pretty decent. But your biggest concern is to see if ALL the cylinders are at 130. Don't take anybody's word for it. A 10% difference should be all you want to notice between each one.
