My boat is a 1997 Fourwinns 205 Sundowner 5.7 Gli
Current prop 14.5 x 23
After sorting my rev counter out I took the boat for a run on flat calm sea's.

Tank 3/4 full
2 adults
WOT 4000
GPS Speed 46mph

Does this sound right ???


Cheers

Sunny UK at last

sound like too much pitch... my best guess would be a 21 pitch to get more pull out of the hole.

your wot should be closer to 4500. but if you like the fuel consumption and holeshot then leave it alone. how often are you at WOT ya know
