Good day,<br /><br />I have a 1974 Johnson 25 hp, model#25E74, serial #C47280 which I will mount on the back of my 14 foot Springbok aluminum fishing boat. Boat has a 15" transom whereas the motor has an approximately 17-17.5" leg. When hung the ventilation plate (cavitation plate) is approximately 2-2.5" below the hull bottom. Is this fine? Or should I make a spacer to raise the ventilation plate up to even with the hull bottom? Or can I just raise it so the plate is only 0.5" below the hull?<br /><br />Another silly question, if I raise the motor up the full 2.5" does the motor still get water under power as the water intake is above the ventilation plate?<br /><br />Thanks for any info.
