Just got a 1998 Yamaha v4 130hp, not allot of hours on the motor, really in good shape fires right up and time really nice. The problem is it seems to have a weak stream of water couldn out of it's pee hole. I've watched a bunch of videos on this motor and all of them seem to have a weak stream. I'm curious if this is a common deal with this motor or maybe a new impellor is needed. Any response would be helpful, thank you
