Volvo Penta 4.3 Gxi Squeal and high pitch noise

[Jimccain]

Hi Guys,

in the two below video there is a squeal that is similar to a belt but not really sure if it is. The belts look new and I don’t see any wear on them. The pulley all looked aligned I have yet to replace the starboard belt I’ve only done the port. I order a new tensioner Incase for the start board engine just Incase. The short video is of the high pitch noise and the long one is the squeal after about 2000 rpm. The starboard engine stalls when dropping back from plane to neutral fairly fast. So you will hear my wife and I discussing restart. Fun fun.

That sounds like a bad fuel cell to me. Similar sound in this video: https://youtu.be/fsmUY2193Js Might start by checking the fuel pressure regulator screen. If that doesn't help, you may need a pump. They are available for much less than the dealer if you do a google search.
