I recently purchased a used boat with a 225 yamaha vmax (2002 model). I dont get the short "beep" from a warning horn when I start it like I used to from my Johnson motor. Is this something I should be hearing or will it just go off if there is low oil or over heating?

It should only go off if theirs a problem. I always like to check the warnings. Heat the temp sender with a bic then check the float warning in the motor mounted tank and the boat mounted main oil tank. You can not be too careful.

Thanks Gary. Where is the sender located?

I always like unhooking the kill switch to see if the alarm goes off when I get a.new boat just to make sure it works aswell
