Poppet Valve replacement is what you should do, I have the same setup and I get 8-10 psi at WOT, I plan to replace my valve soon and have a new water pump/impeller installed in the fall when it gets winterized.
There's a great post about the replacement procedure in the "Yamaha" motor section of the message boards.

take the poppit valve off an clean it out. remember how it goes on. only a few grains of sand in it can make it stick. pretty easy to do
