25 HP on 4 meter sib how fast
I have an evinrude 25 hp till e-tec on a 4 meter Honwave, rigid floor.
Two up, about 30 stone, the max speed is 19 mph by GPS, (flat calm) is this what others get / would expect.
Every thing a full pressure as I have a digital pump.
Have run the motor 1st , 2nd and 3rd trim hole out best performance is with 1st hole but get a lot of spray, 3rd hole gives cleaner wake but less performance.
The cav plate is below the bottom of the hull by an inch or two, would this cause drag, thinking off experimenting wth a block on the transom to raise the motor?
Any other sibbers had similar issues?
Though would have got a bit more out of the, despite being a hefty lump.
