Ok here goes. 1996 Sailfish, 17' length, 8' across beam, I think the weight is 1500 lbs. , motor is a 1988 E60TLCCR. Cav. plate 1/2 inch above bottom of keel line, prop is alum. 13.25 x 15 pitch (borrowed, finally found the stamping). Runs like a champ, 8 seconds to get on plane, top rpm is 4900, slowly creeps to 5050. Speed is ?, speedo doesn't work. WOT range of of motor, per book, is 4500 to 5500. I gotta give the prop back, so here is what I'm thinking.
For the hole shot, get an alum. 4 blade prop, drop an inch for the 4 blade, drop an inch for a little more RPM, so get a 13.25 x 13 alum. prop.
Any thoughts on selection??? Going to order one from iboats today. Could use a little encouragement. Thanks for all the help.
On a side note, I marked the prop to see if it was slipping. Just went out and looked, and the marks are rotated about 160 degrees. Soooo, the prop slipped, how much and when, who knows, but it would show a little higher RPM. So, 13 pith 4 blade prop?
