Formula builds premium performance cruisers and bowriders, and they generally ride behind a MerCruiser Bravo, frequently the Bravo Three with its twin counter-rotating props. That is a capable drive but it carries more bearings, more seals and real load, so it rewards a by-measurement rebuild. Brad rebuilds and repairs the Bravo under a Formula: seals, bearings, gimbal, bellows, cooling and full rebuilds set up to spec. Ship the drive in nationwide or drop it off in Central New York.
Formula sterndrive problems
- Cruise vibration on a Bravo Three from prop or bearing wear
- Milky gear oil from a seal leak in a twin-prop lower unit
- Transom growl from a gimbal bearing on a fast, heavy hull
- Hard shifting or a drive that pops out under load
- Overheating from the engine-mounted water pump or cooling path
- Cracked bellows on a boat that gets run hard
What Brad checks on a Formula drive
- Confirm the Bravo model, often a Bravo Three, and ratio
- Pressure and vacuum test to find the leak
- Measure bearing preload on the higher-load drive
- Set the gear pattern and check the twin-prop lower unit
- Inspect the gimbal bearing, u-joints and bellows
- Verify the engine-mounted water pump and cooling flow
The fix and what to expect
Brad rebuilds or repairs the Formula's Bravo and sets it up by measurement, then pressure tests it, since a fast, finished boat should not come back with a howl or a shake. The Bravo Three in particular has more lower-unit bearings and seals than a single-prop drive, so preload and pattern get set to spec rather than by feel. A full rebuild runs one to two weeks from arrival, with the wear findings and a firm price after teardown.
A Formula usually means a Bravo Three, and that means more to set
The Bravo Three that sits under many Formulas gives great grip with its counter-rotating props, but it carries more moving parts than a single-prop drive: two prop shafts, extra bearings and seals, and tighter setup tolerances. On a fast Formula that all has to be measured, preload set, gear pattern shimmed, and the twin-prop lower unit assembled clean, or the drive will vibrate at cruise and wear itself out early. Brad builds the Bravo Three to spec and tests it before it ships, which is what a premium performance boat needs to run smooth when you open it up.
