prop I.D please help.

[bigoldboy1]

I have asked this question once already under (prop prob) but got no response,can anyone help?The prop in question is a three blade prop and the only markings I can find are :MICHIGAN and the numbers 012049. is there any way I can find out what diameter this is and pitch. I suppose diameter is simply twice the radius but pitch is beyond me.

Hi bigoldboy1 <br /><br />Can't find that one anywhere. Sure it isn't 01204(7) instead of 9?

Re: prop I.D please help.

Just looked in my michigan book. It doesnt list that prop. Could be an odd prop. What size and kind of motor and what size and type of boat are ya runnin?

Hi Saltydog and thanks for the interest. The boat is a 14 ft Marina ski boat and the motor is a Johnson seahorse 75 of about year 1981. The prop on the boat at the moment is 13.25x17 and the problem is that it struggles to pull a skier out of the water and we can,t get a mono skier up from a deep water start but once on the plane it goes quite quick, unfortunately I have neither rev counter or speedo.

Kind of important to know what rpms your runnin at full throttle. Should be about 5200. Id reccomend trying a 13 3/4 by 15p. This should give a little more low end grunt. But i wouldnt reccomend runnin full throttle until ya get a tachometer and find out your rpms at full throttle.
