Re: DUO PROP vs. SINGLE SX ON A V-PENTA 5.0 GXI (270HP)
I have that same boat with a 5.0 SX 220. The 220 is the smallest engine I would put in that boat. It is fine for slalom skiing with a light load of 3 or so people in the boat. It does get a little sluggish out of the hole with 4 adults and 3 small children in it, but is still fine for wakeboarding and 2 ski skiers. I have included a fast facts about the 194 that I got from Four Winns, it may help your decision. One thing I have found is that the 5.0 (carbed or FI), pulls harder out of the hole if it is propped to let it get a bit over 3000 rpm during acceleration. Propping to load the motor too much out of the hole hurts acceleration. The fast facts shows the SX models pulling a 21in. prop. My boat was delivered with a 19 and I run a Volvo 19 SS. With just me in the boat, but full fuel and water, I get right at 48-49 mph at 4800rpm, so I think I am propped right. You will also notice from the charts that the main difference between the SX and the DP is that the DP appears to be planed off at 2500rm, while the SX does not. In reality, the SX 220 in my boat will plane at 2600rpm. Overall, I am pleased with the package. Anyway, here is the fast facts I have for it. Hope this helps...<br /><br />194 FUNSHIP<br /><br />Specifications US METRIC<br />LOA: 213 6.40 m<br />Storage Length: 2111 6.68 m<br />Beam: 8'6" 2.59 m<br />Keel to W/S Shelf: 49 1.45 m<br />Total Height: 5'11" 1.80 m<br />Total Height on Trailer: 7'4" 2.24 m<br />Transom Angle: 13˚ 13˚<br />Deadrise: 17˚ 17˚<br />Bridge Clearance: 4'9" 1.45 m<br />Cockpit Height (stern): 29" 74 cm<br />Cockpit Height (helm): 35" 89 cm<br />Freeboard (min.): 32" 81 cm<br />Draft (drive down): 31" 79 cm<br />Draft (drive up): 14" 36 cm<br />Fuel: 50 gal. 189 l<br />Persons Capacity: 11 11<br />Maximum Capacity: 1700 lbs 771 kg <br /><br />Power Ratings & Weights <br />Engine Propshaft Power Boat & Engine Weights<br />Type HP KW Lbs KG<br /><br />MC4.3L/A 190 142 3700 1680<br />VP 4.3GL/SX 190 142 3750 1700<br />MC4.3MPI/A 220 164 3730 1690<br />VP 4.3GXi/SX 225 169 3780 1710<br />VP 4.3GXi/DP 225 169 3800 1720<br />MC5.0L/A 220 164 3800 1720<br />VP 5.0GL/SX 220 164 3850 1750<br />MC5.0MPI/A 260 194 3810 1730<br />MC5.0MPI/B1 260 194 3900 1770<br />VP5.0GXi/SX 270 201 3860 1750<br />VP5.0GXi/DP 270 201 3880 1760<br /><br />Recommended Engine(s)/Equipment Avg.
