Larry,
Can you paint to match? Is the surface smooth? How much?
Curious on the dimension of the opening and if it is enough to provide additonal airflow besides eliminating vacuum. I have a pair of 3.0l's years back with heads/brucato intakes etc and the boat was 3mph faster with the cowling off. We did some mods and gained 2mph but never got the full 3mph.
I would be willing to take a look at a set. Send a pm with the info.
Thanks

I have the same question as 'Double Rigged' above.

Ok they are made from ABS plastic and one side has a fine texture and the other is smooth . I was planning on offering them with texture out which will closely match the rear vent texture , but I suppose I could make them for you smooth side out . They dont recommend painting ABS but if you know what you doing ( scuff pad , adheasion promoter ) you will be fine .
Dont have any Data and will never claim HP gain ! That said the opening is 2.5 " x 3/8 " and any engine on planet will run better with direct cool air Vs ais being drawn in over hot engine prior to being injested . I may offer @ extra charge pair painted black

How waterproof are these? Spray or rain water won't get in ?

How are you doing? Been enjoying your Skater?
Larry is a very talented guy, and is really on to something
here, in relieving the vacuum from the rear intake, which
ingests the spray. As a side benefit, we should get cooler
air going into the engine, and that is always a good thing.
I am very interested, but will probably keep them covered
when the boat is not in use. Here in FL, it rains like a
monsoon during the summer.
As far as spray, I would rather get occasional spray from
the front, than continuous spray from the back.
I am sure Larry will check all of this out, and let us know.

I keep my motors covered when not in use.
Would love to try some. When can you ship?

Will keep you all posted , 2 weeks or so . They look simple , but I have many hours in tooling and after pulled from mold I have to trim by hand , install 3M double sided tape .

Looks like an AC vent for a small cruiser,I would NOT have that crap on my cowl.I imagine driving in the rain,would ingestion water the air intake
