    Great prop sepc info

    Guys here is some great info on sizing your boat for a prop. If you need help or have any questions about this get in touch with myself or Matt at boats of Nevada. We can help you and we have a contact at ACME to help us. I did make a change to my name and to some of the personal info ACME gave me through email to reserve confidentiality. Other than that everything else is info right from the ACME Sales Engineer at ACME.

    Hello again anhaney,

    Just some inside information for you on the sizing of 24V's, and the sizing of other Tige V-drive, gear-reduction boats.

    The current (stock) prop on the boat should be an Acme part number 537. And the 537 (13.5 x 16, 4Bld) is the best choice for all-round performance on the 24V when the boat is being used below approx. 3500 ft elevation, and/or when the boat is used for a variety of applications (cruising, skiing, tubing, moderately-loaded wakeboarding, etc.), and/or when the boat is generally loaded with no more than factory ballast and an average load of people.

    However, if the 24V is being used at higher than 3500 ft elevation, and if it is being used predominantly for wakeboarding/wakesurfing, and/or if fat sacs, or lead, or a lot of additional people are being added to the boat (above and beyond factory ballast) ---- and thus the customer doesn't mind giving up about 4 mph in top end speed in order to gain some bottom end torque --- then the 24V can run an Acme 14.25 pitch prop, for added torque and fuel efficiency under heavy load.

    Now... What are the different part numbers available in 14.25" pitch? Options for the Tiges are as follows:
    #1235, 14.50 X 14.25 VL4B 1.125 Bore .105 Cup
    #1273 14.50 X 14.25 VL4B 1.125 Bore .150 Cup
    #1465, 13.50 X 14.25 VL4B 1.125 Bore .105 Cup
    #1237, 13.50 X 14.25 VL4B 1.125 Bore .150 Cup

    Please note: A Tige 24Ve definitely has the required clearance needed (between the prop and the bottom of the boat) to turn an Acme 1235 or 1273. And it is my understanding that this model (the 24Ve) has had the necessary clearance since its introduction. However, the other Tige V-Drives prior to 2008, including the 24V, may or may not be able to turn the extra diameter of the 1235 & 1273 (because they may or may not have the necessary clearance between the prop and the bottom of the boat).

    (Reference point: A boat should have at the very least 3/4" or more clearance between the prop and the bottom of the boat. On some boats, with some props, an inch or more of clearance is preferred.)

    According to Tige, most of the 2008 V-Drives can turn the larger, 14.5" diameter propellers. The 2008, 20i, 20V and 22i definitely CANNOT turn the larger, 14.5" diameter props. Of course, when we speak of the 14.25" pitch props, it is important to note that we are always talking about the boats that have the gear reduction. Many of the 20i and 22i boats have a 1 to 1 gear (no reduction). As a result (of the 1:1), they will typically run an Acme 13 x 12 or an Acme 13 x 11.5, 3-Blade (Acme part number 515 or 525), and again these boats cannot turn the 14.25" pitch props.

    If you or Matt or anyone else have any questions or concerns regarding the sizing of whatever boats for whatever applications, just give us a call.

    Thank you and best regards,

    Sales Engineer

    I get the diameter and the pitch.
    What is the difference in a .150 vs .105 cup going to do?

      I am not 100% sure but I think it has to do with the amout of slipage allowed between the prop and the water. Which would effect hole shot on one end and top end on the other. I will research this and try to find out for you.

        Thanks for posting this info. I used to carry a spare prop on my old IO that was a bit smaller than the prop I normally ran. The smaller Prop gave me a great hole shot but I lost about 10MPH on the top end.
        I am wondering how many of you carry a spare prop on your Tiges?
        I am thinking about buying a spare for peace of mind and I have to think a smaller prop would be easier on the engine and trans when we are running 2000-2500 lbs of ballast for wakeboarding and surfing. What are your thoughts?

          Spares I carry in the boat - fuses, serpentine belt, spark plug, plug wire, cap/rotor, water seperator filter, wire, hose, clamps & oil (engine,trans,V-drive). Always take a prop, raw water pump and starter with us in the RV. They aren't too hard to change and are the things that get used the most.

            You're correct. I think larger the cup size, the better the top end performance.
