I have a 1999 Volvo Penta 5.0GI PWTR with SX-M 1.60 drive. A can't find the correct part number for the gimbal bearing. I'm also trying to determine if I will need a gimbal bearing seal. If I use OEM bellows should I use a sealant? I found the drawing for the drive shaft on volvopentastore.com under Volvo Penta Store - Marine Engine Parts, Propellers & AccessoriesMarine Drives & TransmissionsMarine Drives & Transmissions Parts Catalog - 7746020Transmissions, but it doesn't appear to have the gimbal shown.
