Puddle Valve Inconsistancy

[boatmon345]

Rebuilding 1997 Yamaha 150HP 2 stroke S150TXRV powerhead.<br />( Click here to view updated blog with new pictures )<br /><br />Rodbolt, read your explanation of puddle valves, and it helped, but still have questions ( manual is incomplete ).<br /><br />Cleaning the block today I blew compressed air into my puddle valves from the outside to inside and all allowed unrestriced air to pass except for #3 which appears 90% blocked.<br /><br />Blowing from inside of cylinder puddle-valve-opening to the outside is blocked on all cylinders (no flow).<br /><br />Looked at a parts website and noticed that I have "check valve" and "check valve assembly". <br /><br />Is this correct operation with the exception of #3? <br /><br />What to do with #3?

just snatch them all out and replace them, not like they are expensive.<br /> they are a light press fit in the block.<br />i usually wipe them with gel seal or the loctite 517 that you use for the crank case halves.

twist out, pull out, cut-off or kick?

clamp vise grips on them and twist away.
