hello everyone, new memeber...i am looking for some boating wisdom and advice. i have a small 17ft bayliner capri with oem force 70hp outboard. i had some prop damage last weekend and am looking for some help. i have a 10-1/8 15p that i will be replacing. my question is what kind of difference am i looking at by possibly changing diam and pitch. the issue is my first boat is pretty basic, it does not have a tach so i cant judge rpms. with the oem prop, it just seemed like the motor had more potential. ill be pulling tubes and wakeboarders aswell. thanks in advance.
Unfortunately unless someone has the exact same setup there is no way to make an accurate suggestion for a prop especially
for an up grade.For the health of your motor you need a tach,A Tinytach ($47)will work on your motor and any future motors.
They have a web site,be sure to read all the information.A gps for speed is ideal,some cells have a gps app.
We need your wot rpm and speed to tell how well your motor is working and to tell if your setup is right.
If there is a prop change we need wot rpm and speed to be sure the motor is operating within its rated range.
Without any info I would suggest the same prop.There are also some changes that could be made to help your performance.
You should check to see if a repair is possible and cost effective.
