Wellcraft built a huge run of I/O runabouts and cuddy cruisers, and because that run spans decades, a Wellcraft can carry a MerCruiser, an OMC Cobra or King Cobra, or a Volvo drive. The OMC drives in particular are getting hard to find service for, and OMC is one Brad still rebuilds. He repairs and rebuilds whatever drive is under your Wellcraft: seals, bearings, gimbal, bellows, cooling, shifting and full rebuilds. Ship it in from anywhere or drop it off locally.
Wellcraft sterndrive problems
- Water in the gear oil from an aging seal on any of the three brands
- Transom growl from a gimbal bearing on an older drive
- OMC Cobra shift or electric-shift trouble
- Overheating from a worn impeller or restricted cooling
- Dried, cracked bellows on a decades-old boat
- Gear whine or clunk from wear on a high-hour drive
What Brad checks on a Wellcraft drive
- Identify the drive, MerCruiser, OMC Cobra or King Cobra, or Volvo
- Pressure and vacuum test to find the leak
- Inspect the OMC shift system on Cobra drives
- Check the gimbal bearing, u-joints and bellows
- Verify the water pump and cooling flow
- Read the gear oil and flag any scarce OMC parts early
The fix and what to expect
Brad identifies the Wellcraft's drive first, MerCruiser, OMC or Volvo, then repairs the fault or rebuilds the unit when wear runs deep, and pressure tests it. The OMC Cobra and King Cobra are where a lot of shops turn owners away, and those are drives Brad still rebuilds, flagging any hard-to-find parts up front. Single repairs turn around fast, rebuilds run one to two weeks from arrival, with an honest timeline on the older units.
The OMC Cobra under many Wellcrafts is Brad's advantage
What makes Wellcraft different from the newer I/O brands is the OMC Cobra and King Cobra drives found under so many of them. OMC left the sterndrive business years ago, so parts and know-how are scarce and many shops simply will not touch a Cobra. Brad still rebuilds them, including the electric shift and the cooling quirks that come with the older units. If your Wellcraft has an OMC drive, that is exactly the kind of orphaned job Brad takes on, and he will tell you early if a specific part is going to set the timeline.
