Not knowing the pitch of the prop it is difficult to say. The diameter of 13in is only part of the equation. I have a flat bottom boat with an engine that has been built to the hilt. The prop I have on it is a three bladed 12/15 with a cup built in. the 12 is the diameter and the 15 is the pitch, that means for every revolution of the prop, in a perfect situation, my boat should travel 15 inches forward and if I factor in the revolutions of the prop shaft (About the same as the engine in this case) I can predict my speed. By the way we calculate the boat can now reach 90/95mph but if I change the prop to a two bladed, the boat should be able to reach 110 or better. The two bladed prop is more efficient, the down side is it has no “grunt”

+ That baby will fly. I need more info for exact speed. Is it a deep Vee hull? How many feet long? It would go slower if it is loaded with 200lbs of gear and 3 or 4 people.
I have a 16 1/2 foot tracker aluminum Deep Vee Guide. It is fully outfitted with all the CG equipment plus some. It has a new 15HP Merc 4 stroke with factory prop long shaft. With two full size adults it does 20MPH on glass flat water with no problems. It will slap in 4 to 6" seas, but still do the same speed.

If you are referring to that 10 1/2 X 13 black max aluminium, I would say around 29mph, give or take 0.5 mph. The prop I suggested in a earlier question would do you better. I think it was the 10.75 X 12 SS, it's faster. If you want the part # I'll look it up, just let me know.......So you know, I based this on an engine heighth second hole from the bottom.

With the given information, still would need the max rpm you are turning and the year or serial number of the motor, with a 1.83 gear ratio, turning 5500 rpm with a 10% slip factored in you would be at 33 mph. if you want to try other rpms try this site.

To figure the speed that a boat can attain you need to know the hull shape and the length. Certainly what you describe will plane. It sounds like it will act like a hydroplane.

depends on the length of the boat but it sounds like it will FLY
