I have a 2020 f90 that stalled while at high rpm. Started back up but making a rattle noise and blowing bubbles up from the lower unit area. Rattle speeds up with rpm but idles fine. I have not reved it up very far
 
Gears are always turning when engine runs in neutral.-------Checked timing belt and valve clearance?-----Is there a warranty on these expensive motors ?

3 year warranty. It's only got 160 hrs but that's the way it goes. I've not gone into the engine. I'm going to check minor stuff and take it to the shop if I don't see anything. I did find a small rubber house that is split down by the lower unit. Not sure what it is yet
 
The small hose is likely a feed for the speedometer.-----Nothing to do with noisy motor.----Hurry to your local shop.

It does not have a speedometer. I thought it may be the cause of the bubbles if it
was some sort of vent hose. I don't necessarily want to go to a shop, but if I don't have the tooling to work on specific things it will be less costly than buying tools i may never need again
 
I think it is the hose for the speedometer.----But hurry to your local friendly dealer.----Perhaps something can be worked out on warranty !

It appears I lost a seal in the lower unit. I checked the gear oil and it was dry. Spoke with a local shop that said if it's more than seals replace the en lower. Seems extreme to me
