Location: Eastern Ontario | Son in law has a 16.5 Lowe SC with a 75 etech with just him in the boat he hits 40 mph with a wot and 5900 rpm
He has an unknown brand stainless prop marked 13.5 x 18 also marked 763 953 boat was bought used.
His problem is getting heavier teens up water skiing he says the bow doesn't come down quick enough and it seems to cavitate . He asked about a dole fin type of thing and I wondered about a different aluminum prop for skiing . Your thoughts please. |

Location: Eastern Ontario | Thanks Steve that's sort of what I was thinking would you go 4 blade or stay with 3 and would a 17 be dropping enough?

Location: Elk River, Minnesota | If it's a 13.5 x 18, and it has vent holes that are about 3/8", I'll bet it is a raker propeller... good prop for lift and top end, not so much for skiing. A good 4 blade in a 15 pitch would do very well as Steve mentioned...
