NO...it is not true. If you are running a 7.4 (non mag motor), then your rpm range should be around 4200 to 4600 and no more. Turning a 7.4 up to 5000 and more is not pushing the limits...it is shoving the limits. More than likely, you will have a rod hanging out the side of it.

Agree...

My 29ol with 7.4 MPI's rev limiters kicked-in about 4650, but the older 7.4 carbed motors like my 92' 240 would run almost 5000 if overtrimmed with a 23p Mirage. Rev limiters were the best thing invented for marine engines...

XT

100% right!! if you had MAGs (385hp) not MPIs (310hp) you would be able to push them a little more. Not the MPIs ive been thought this already.

good luck.

did you change your fuel/water filter that can cause a loss of 200 rpm. give brett at bblades a call he has a prop exchange program, but if you didn't change the f/w sep do that 1st.your hull is different from the ol hull your is a 21 degree if I remember 240 sport /ol was 24 degree.

thanks guys, i looked on my motor covers and it dose say rpm 4200-4600 so i should be able to pull 4600 right, but im not so i guess ill try a smaller pich prop

Call brett he has a prop exchange he may let you try a small prop but it might be higher rpms but slower speed. you will pick up speed with a labbing a prop and rpms. also check the fliter I told you if you did not put a new one in. a labbing can get you up to 300 rpm. but brett may want you to try a rev 4 prop 25p they have worked good in bajas cause of the deep X= deep prop shaft. I will ask him to look over here if he has a chance he could explain better than me. your boat should be faster than a ol 24 cause its lighter/smaller deadrise 21 degree not a 24 just don't go buying props from Co's that once you buy it your stuck with it. call me if you want 617 833 3327, just hanging around two day waiting for flywheel and driveplates so we can put the 1100sc in the boat.

thats cool ill try to call you later thanks
