I am looking for a good replacement prop for my 2015 Monterey 204FSX with a the Volvo Penta V8 270 HP and a 1.60 SX Drive. The boat is about 20 feet in length and weights 3,100 pounds stock. The boat currently has the OEM aluminum Volvo Penta 14 1/4 x 21P, which seems to be a good "all around" prop for average weight loads and cruising. However, when tubing with the kids or having more than the norm in people on board, it seems to be a little sluggish out of the hole with top end being fairly good. But I will admit, I very rarely open it up all the way. WOT for the motor is 4600 - 5000 and I have had it to around 4900 (kinda bouncing between 4800 - 4900) on the tach, with a speed 57 with two people, very light load of fuel, and smooth as glass. But since it was speedo on boat, I do not necessarily believe it. I would like to stay with an aluminum prop and have considered going to a 19P prop for better holeshot knowing I will loose some top end and it will drink a little more fuel. Another thought would be going to a 4 blade 20P, which I think would help with holeshot and mid-range and might not be a killer on fuel consumption (hopefully somebody chimes in on if I am correct on this). Not overly concerned with having the fastest boat, just one that does what I want. Any suggestions or recommendations on replacements? Should I stay with VP brand or are there other aftermarket props that are better for the money. Any help is greatly appreciated...... Thanks
