yam 360s

[billows]

I have bought one second hand and there is no plate but has a gauge.What air pressure do I need for keel and tubes?

as i remember i just blew my yam 380 till it was solid nice and firm with a stirrup type pump as it has a wooden deck pressure is not as essential as in the bombards with airdecks i would imagine it was approx 2- 2,5 psi and the keel just till its nice and firm
sure theres a few yam owners who will tell you exactly whats required
