hi all i have a problem with my osprey sparrowhalk rib , when i jump a wave it tends to dive to the left side as i leave water and im looking for help to find out why its happening as it only started a few weeks ago also is a 115hp outboard to power full for a 5.2 meter rib NEED HELP ASAP PLEASE
The most likely cause will be too much weight on the port side of the boat, or the torque of the motor pulling it over. The Sparrowhawk is a light boat and is only rated to 90hp max , so it could be that the engine is the cause.
What i have seen on older Osprey`s is that they havent installed any drainplug on the transom.
Some boats i have been taken to Swe i have drilled a hole and it`s been couple of hundreds of liters in the hull.
It can be one of the cause but most likely its the engine, 115hp on a Sparrohawk is overpowered but as you said it started recently.
Try to compensate the rotation of the prop by turning quickly with the steeringwheel to the right and se what happends, if boat is running straight in the waves it should be the cause.
