    Default school me on low-profile intakes?

    we don't see low profile intake much in this part of the country and i've been wondering about low much better they work compared to a standard mb1201 dominator intake?
    is the intake ramp angle just lower down, therefore the pump sets closer to keel and results in more lift?

    A low profile intake moves the pump lower in the hull and makes the loading of the pump a little easier. You are decreasing the angle that the water has to take when getting into the pump ... the more that the water has to change direction, the more power it takes to do so.

    Here is a pic of my low profile intake ... not cleaned up yet, but you ca see how low the ramp/rise is in relation to where the pump bolts up compared to stock:

    if you had a "profile" pic of a low profile intake next to a standard intake with suction pieces attached to both, it would be easier to explain because you can visualize what's happening. in addition to aligning the pump better to the water stream, the lowpro intake reduces the volumetric area between the hole in the bottom and the roof of the suction piece, where water can become very turbulent at high speeds. at speed, you want flow to be as smooth and direct to the face of the impeller as possible, and the low profile accomplishes that.

    I would guess the bottom line here would be.......is it worth the expense and work to make the change if you're a lake/river boater or is it aimed more towards racers? And how many racers run these (ratio) as opposed to the normal profile?

    How's the cruiser coming along bp?

    I think the majority of racers are running a standard intake. There are a few running the low profile and they really do make a difference. Now that MPD is casting a newer version of them I think the number will rise.

    If you look at the pics that are posted of Joe Lakamps Cp in the "jet boat pics" section you can see the differences in how the boat rides.

    that's the pic that got the gears turnin in my head, that boat rides aweessssomeeeeee

    thanx for the info guys, i thought about the ramp angle helping alot but didn't think about it lower the intake"plenum" volume , be like closing the hole up some with shoe, but without the negative side effects.

    if it's a boat that only runs on the river/lake, but is really fast?, yeah it's worth the effort to go in that direction. and i really hate to disagree with jordan, but the vast majority of race jets have some type of lopro intake installed. they've been around for a very very long time from one manufacturer or another, but the new mpd casting is the best of the bunch. mine is an old alpha marine lopro that's been around for at least 30 years.

    it's all together, at least to the point i'm going to go for this summer/fall. still need to take it to kingman to get the reg transferred to az before taking it out. but getting ready for next weeks trip to redbluff, so it'll be a couple weeks yet. next winter it'll get fixed up a little more, then a little more the winter after that... floor turned out bitchen'
