Hi, I am trying to find what picth prop i should have for a 1987 Force 85 hp with a 17 foot bayliner boat.the numbers on the old prop r wore off.i would like to know what pitch it came with out of the factory or what pitch i should be using. I dont think the prop that is on their is right as my tach reads around 4300 rpm WOT,and i have read where it should be around 5500 rpm.Thanku for your help and time.

Howdy, Bono.<br /><br />First, make sure that your engine is running properly. It is possible that it once turned 5500 with that prop.<br /><br />If your engine is in good shape, pull the prop and take it to a prop shop. Tell them your situation. <br /><br />You probably need about 2" less pitch, but see if you can test the prop before you buy it. Select the pitch that will get you to 5500 with a light load, 5200-5300 with an average load, and 5000 with a heavy load.<br /><br />Good luck. :)
