I've personally never seen a "spooned" boat other than your's but it appears to work great. Since the spoon has to be bent/shaped they must be constructed of lighter material that is more apt to get dented/misshaped once again causing cavitation...possibly worse than it was before. In the shallow rocky rivers I run, a spoon probably wouldn't last a whole season that's why the flat bottom guys are going with the reverse tunnel design because it can be made of 1/4" material if need be.
they make performance intake grates that scoop the water you should look into that before you make a spoon I've had a jet boat fabricated which is the one in my signature and I built one neither one needed a spoon...
also they work to I had two identical skis except one had the performance grate and the other did not it made a huge impact on speed.
There is also a you tube video of a home made jet jon like ours where the guy tested it and it cavitated the whole time and in his second trial video he had put the grate on and it ran good.
Loader style grates work good but offer no protection against rocks/debris and although I cant prove it, I believe the extra bite causes the boat to ride lower in the water.
AMK - Thanks for the tip on the loader grate. I'll look for one on ebay. I am wondering how big of impact it would take to rip my spoon off & then I would have 6 holes letting water in.
I don't know if I'd like the grate. One great benefit of my spoon is I can run through weed beds at speed and not clog the intake with trash. I figured it was due to how the spoon pushed the weeds away while sucking the water up the reverse slope and any vegetation would just slide across the grill. It also won't grab at anything that hits it (stick, rock ledges, etc).
Ranchero - Yours looks very beefy, that is just another benefit of all metal design. My spoon has to connect alum & fiberglass both. Found a top load grate (Solas) on ebay for a good price, going to try both & see which one works best.
Well I finally figured out the engine problems turned out to be the fuel pump on the carb one of the gaskets were a little big and would allow the engine to idle but when you rev it up it would suck air , run great now

Trim tabs will extend the center of balance further forward without adding more weight up front. I ran into that issue with mine after doing a 1" step in the hull up to the bottom of the pod.
