honda 225 overheat at 4000rpm

[makyr17]

having over heat issues at 4000
replaced thermostats and impeller with housing
cleaned the poppet valves ... was full of salt pieces
now the engine can stay on 4000 longer until over heat comes
any ideas what to do next to remove this issue?

Hi,
I'm not the 225 expert here. Never worked on one. But I've seen posts here about guys finding crap built up in the exhaust manifold hoses.
See items 6, 8 and 9 in link.

Good luck.
