Like I said before with the propeller shaft being tested new propeller, new cutless bearing I rebuilt the transmission so yes the engine mounts may be alittle worn but idle to max rpms is extremely smooth. One thing when I called PSS they asked if I heard a noise coming from it and even when it was hot I heard nothing. I hope that it being as warm as it is isn't uncommon just curious why some would be cold or barely warm this one being at the max spec.
