    Default Con's (and Pro's) of a Low Profile Intake??

    I think I know most of the advantages of a Low Profile Intake (but feel free to talk about them more) but what are, if any, the disadvantages/problems one may run into when switching to one?
    Are they hull specific?

    Thanks!

    Alot of the guys in the know are out of town right now at the races.
    I am sure there are still a few people that will post up. I run an old style low pro "R" and it's disadvantages are, it only takes certian hardware and is not interchangable with the standard 4* stuff. The advantage i see is you don't need to bend the water flow to have it exit out of the bowl.

    it's much easier to show and tell rather than just try to describe.

    the lopro reduces the area (height/width) of the water entry point. this can help control overloading at high speed, but it also allows a smoother and less radical upper entry angle, which is more effective in loading the pump at speed. some are better at accomplishing this than others. imo, mpd's new one is the best available, as is being demonstrated on the track. thousands of hours, and decades of r&d went into it.
    mine is an old old old alpha marine intake. it works very well, although it very different from others designs.

    I like the low pro so you dont have to run the shoe or loader so deap. I dont know about over loading one , if you do I think your trying to hard.
    How about blockers and low pro intakes.

    If you look at pictures of boats, same hulls, similar (HP) set-ups, with lo profile intake and with a standard intake....You can see how different the boats ride. As for draw backs.....none in performance, or safety......but being so low in the hull, you run into clearance issues with the engine. Longer drive lines are some times required, to maintain engine / hull clearance, and proper drive line angles. These are some things Jack (MPD) discussed with me prior to going the lo profile route.

    Talking about drive line angles. I have a 12 long shaft and the motor sits at 5* in the boat. Looks kind of funky untill you get used to it.

    the lopo sits the pump more forward right? so did you have to do any hull work to set it back more or did you use the ole intake spot? i've decided to keep my boat and do some upgrades to it , intake replacement being 1 of them

    The only con is that you loose the maximum amount of "up" that can be adjusted on the plate......and it seems that every gullwing I've seen runs the best w/ the plate at a pretty high angle (or at least more than you would expect).

    Well that.....and then you have to make mounts to get the engine at the same angle as the pump.....and making sure the driveline is long enough to not put the pan on the hull when all is mounted.

    Default lo profile

    I've had to trim my oil pan to fit. Otherwise it hits the bottom of the boat.
    Only about 3/4" up and 3-4" long wedge from the bottom rear.

    are most of the low profile intake variations all the basic berk/dom pump pattern(pattern to the pump, not hull)? if someone installed the low pro in the same spot as the standard intake, how far forward would the pump move?

    It will change.....and it will be custom. Every lowpro intake out there is going to be a little different as to the position because the height on the pump mounting surface are not likely to be identical. (some lower/some higher)

    ohhh, i gotcha. so if 1 was looking to buy a used low pro he better look for 1 that came outta a similiar hull so placement angle will be close, right? trying to learn here guys gonna be layin down a lil bit more hp next season and i want this lake biatch to crack 115 with the bench seat in it i'm pulling the motor and pump this weekend, getting the hull off the trailer, and gettin busy on the trailer.motor will be done by mid january, and i wanna start on the intake pretty soon while we still have some decent temps here. my shop will only get to 75 here during the winter.

    how much lower did the motor have to drop on your's sleek?



    if anybody has a low pro outta a 19 gullwing in good shape, holla at ya boyyy
