Will the HC5332 Fit?
Dometic lists HC5332 for the non-power-assist applications below. This is not a universal sterndrive cylinder, so the complete drive and steering configuration should be checked before ordering.

|---|---|---|
| MerCruiser | Alpha I, Bravo I, Bravo II and Bravo III, 2000 to date | Non-power-assist steering only. |
| Volvo | 290, diesel and selected DPS applications | Confirm the transom-shield configuration. |

Send us: drive manufacturer, exact drive model, model year and whether power assist is present. Brand or horsepower alone is not enough to confirm fitment.
