Most service parts like bellows, gimble bearings, u joints, impellers, tune up parts are available in from the OEM (Bombardier, who bought the assets of OMC) and aftermarket. Some parts are hard to find, like the EFI parts and the electronic igntion parts. If you keep after the Cobra it will last a long time. I've had mine almost 20 years and while I've done a lot of repairs on this boat (age, wood rot, upholstery, some engine repairs) the Cobra itself, has been VERY good. Very few repairs, it does get regular maintenance. Nearly 20 years in salt water, not a trailer boat but on a mooring in salt water. Now these can be converted to a Volvo Penta SX, because the transom mounts are very similar, but it can be a bit pricey due to the cost of Volvo parts. However, if you REALLY like that boat, it eliminates the concerns with parts and finding mechanics who can work on them. I do all my own maintenance and have a supply of spare parts I keep on hand and also big items like a spare outdrive and transom mount. Mostly ebay good deals.
