prop slip?

Postby waterfowler9 » Sun Sep 08, 2013 7:29 am

I have a 1860 boat with a 50 hp Mercury 2 stroke tiller. When i am trimmed down all the way and punch the throttle to get up on plan the motor or prop almost studders before catching. Its almost like the prop is being ran through mud before if gets up on plane, but i am in deep enough water. When the motor is trimmed up and the throttle is punched the water pressure pushes and trims the motor down and the slip in not noticeable. I believe i am running a 10 3/8 X 11 stainless.

U sure its prop slip and not a carb or gas line issue showing itself under load and pressure. Even a tiny air leak will give u a stutter at take off under pressure.

I am pretty sure it is not a fuel line issue. As far as a carb. issue i always run a fuel stabilizer (startron) and every other tank run mercury quick clean through the motor.

Sounds like you may be over propped for your load. Has it always had this problem?
