I recently boat a 1994 Vanguard Phantom 17' with a closed bow. It came with a Suzuki 150hp oil injected outboard motor. Noticed the tansom had build reinforced with a metal. I looked at the recommended max hp rating tag on the boat says 53kw (70hp) this presence a concern. I couldn't help notice that other similar boats of different years have large motors too. Does anyone know the specs/recommendations as what is allowed or recommended? Is this an issue where I hae to down-size the motor?
