Well, I have a 21 p2 w/ a 4s 200 proxs. My boat came with a 24p fury 3. Couldn’t get rpms up over 55-5600. Dealer was nice and swapped out 24 for a 23. That got me up to 57-5800 at 68-69 mph. Been running that for a few months and works pretty good, ran the fury 3 3/8 ptp. Getting speed of graph and rpm from smart craft. Just me usually, water in livewells and a 1/2 to full tank of gas, for testing purposes.
Saw this post a while back and figured would give trophy plus 23 a try, got one for a really good deal.
Played with settings a bit, setup the way was suggested with blowout ring, 2 solid pvs and 2 partial pvs at 2 7/8 ptp. Had horrible cavitation on holeshot and would almost freerev on acceleration, so had to change something. I lowered the motor to 3 7/16 and still had bad holeshot and cavitation. I plugged all the holes on the prop and lowered the engine, I am at 3 9/16 prop to pad now and holeshot is awesome. I can get it up to about 67 at 5900 rpms now. But chine comes on strong at about 65-66 mph. Going to try raising motor up a quarter inch and see what happens. Maybe plugging the PVS plugs all down fixed the holeshot, raising it a little will help with the chine. Should be doing changes 1 thing at a time, but time doesn’t always allow.
I leveled the boat on the trailer with a 4 ft level, using the tongue jack. Leveled the lower unit off of the cavitation plate with a torpedo level with the trim switch. Measured at bottom of pad and centerline if prop shaft at rear to the garage floor. Did this to get baseline. On my boat inner and outer plates on jackplate level is about 4 inches prop to pad. So once you know that you can make changes at the jack plate and add/substrate from your baseline to get prop to pad after adjusting at jack plate. Guessing each boat is slightly difference.
Never had any issues with water pressure at any engine height I tried. Always seems to run 15-20 when up to speed. No issues with water temp.
Been trying to learn how to prevent the chine walking from starting, and getting better, but need more practice. Some good info on this forum for that.
One thing I did notice over the 23 fury 3, the trophy seems to get worse gas mileage. Guessing because is 4 blades vs 3, more drag maybe. Maybe wrong terminology but the fury 3 seems to hook up better in a straight line once you get going and run flatter. The trophy seems to work better at midrange speeds, handling and holeshot with a load. I’m thinking the trophy plus will be better in summer when it’s hot and have a heavy load, fury colder weather when it can run.
Been trying to get over 70 safely, kind of feel like after get there won’t be as important anymore. Just kind of a goal at this point. Seems like everyone else with this boat gets there pretty easily. So might just be the loose nut behind the wheel.
