    Default 2" Shorty lower unit

    Looking at picking up a used Sportmaster shorty for my Eliminator Daytona 26. Engine is at 920 hp, max speed should be over 100. What are the advantages of going with the Sportmaster or something similar? I have heard plus 5 mph or so? Any drawbacks other than the cost compared to a standard XR lower?

    Thanks, Walt

    Measure your propshaft height compared to outside sponson depth. Very critical on a Daytona. Also is it open or closed bow? We have lots of experience with Daytona's. Doing a 2" lower on a Daytona right now.
    Give me a call and I can help you with advice.

    not buttin' in, but where do you want the propshaft ! even with the bottom of the sponsons, or higher? I know it prob. depends on the hull,
    power/ weight distribution, just curious!

    Definitely depends on the hull. Single, twin, length, open or closed bow, how many steps.......
