how it going. i have a 1991 sunbird corsair 198 cuddy cabin with an omc 3.0 4 cly 130 hp. currently i am running a 14.5 x 19 three blade cupped prop aluminum. i am not shure or the gearing and the prop was the one that came with the boat. my problem is that if i have two or more people the boat will not plane or break 13 mph(gps speed) and will not go above 2600 rpm. but if i am alone the boat picks rite up and goes about 25 mph at about 3400 rpm and thats it it wont go any more. . the recomended rpm is 4000-4400. if i down size down pitch would the boat be better.should i try a 4 blade maybe a s\s im stuck and dont know what to try next. i use the boat for tubing skiing cruising. thank you
