Whistling engine at RPM Printed From: CorrectCraftFan.com Category: Repairs and Maintenance Forum Name: Engine Repair Forum Discription: Engine problems and solutions URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=39017 Printed Date: April-28-2024 at 10:13pm Topic: Whistling engine at RPM Posted By: Heaktwin Subject: Whistling engine at RPM Date Posted: June-16-2016 at 12:44pm I have a 1994 Nautique with the ProBoss engine....I am getting a noticeable whistle at about 2300 RPM. The whistle goes away at 3200 RPM, so although there is no noticeable issues with the engine performance I am wondering if this is an indication of the shaft stuffing bearing failing or if this is an air intake whistle that is normal. Anyone out there have any experience with this? Thanks!! ------------- heaktwin
