444/44/396 turbo not spooling up

[Huckleberry]

Thanks V57 . I am anxious to try your suggestions . The boat has been on the hard for two months . Hopefully it will be back in its slip in the nest week or so , so I can start checking . To your knowledge (you seem to have a lot) is there anything they could have disconnected or broke while removing & installing the new air filter ?

There's nothing they could have broken if only replacing the air filter. It literally just sits in a metal sleeve in front of the turbo air intake. Once you pull the filter out and look in there you'll see what I mean.

Still waiting for boat to get back from shop and in the water so I can get this figured out .

Yeah ! Problem found and fixed ! The hose between the turbo and the manifold somehow just slightly slipped off on one side . Clamps were not tight enough . This caused the turbo to have no boost effect . Slid id back up , tightened hose clamps and problem solved ! Thanks everyone for your input and suggestions .

Gotta love it when the solution is so simple not to mention inexpensive. If you can, post a picture of the hose/clamp in question. Thanks for posting.

Thanks for the follow up. Glad it was an easy fix that didn't cost anything, those are the best!

Hard to see but the red hose should be down over the white collar .
