We hit a VW size rock above the Needles bridge and knocked a 'chunk' off our skeg, Prime Marine fixed it for us RiverDave sold us a prop
But then the little thingys that lift the engine drive up and down blew up.
I guess when you hit stuff, you need to know if they were running an aluminum or steel prop. If a steel prop, they could have damaged the engine drive thingy
Do you want pics?
