I have recently purchased a 1994 celebrity 24' br. I have been havin trouble finding any info on the boat or out drive. I purchased the boat for a very fair price with the understanding it needs a bunch of work. But motor works great but a few issues with the outdrive. Motor is yamaha 454 with yamaha hydra drive that I am not familiar with at all. So I'm look for any kind of help with boat I can find. Just a few questions. Does the outdrive have a filter or screen for oil if so where would it be located. What type of gear oil do they use and how much. Thanks to anyone for any help thanks John
