So here's an update on the build, I ditched the pods and made different mounts for the trim tabs. So far I've had it up to 39mph at fI'll throttle withe no porpoising. Which yes, is fast for a Jon boat, but with 120hp I think it should go much faster. Especially when I've seen some with 60hp...

If you made them flush with the bottom of the boat then it probably would help with porpoising but I had them set up an inch off the bottom to alow for the trim tabs underneath

I had actually fabbed up a set of pods and was going to do like Ranchero50 did and step them up off the bottom and have the trim tabs underneath but decided not to. The only downside of trying to use pods as trim tabs is they won't be adjustable. If your just looking to add length then they'd...

Sorry for the pictures bwing upside down, I've tried to fix em 3 tines and it won't seem to upload them right.

I made a monster set of trim tabs for it, once I figure out where they work best I'm going to shim the ride plate down to match them. I tried everything you could think of (except shiming the ride plate) to get rid of the porpoising and nothing worked. I also moved my steering up front to get...

Hey Adrian, sorry for the late reply. I used expansion joint caulk and 3/8" carriage bolts to secure the jet ski hull to the Jon boat. It worked very well. I am have installed the trim tabs but have not tested it out yet as I am trying to 100% finish the boat so all the weight is where it will...

Do you think adding pods and making trim tabs like yours would do the trick?

So your pump is pretty much level coming out of the back of the boat? I'll post some picture of what I had. I pulled it all apart now because I couldn't get it figure out but it looks very similar to your with how you have your entire pump put of the back. Only difference being my boat is 2ft...

Getting ready to put my motor and pump back in my jet Jon. I originally installed it with the pump nozzle at 0° and with the trim nozzle gave me a range of +15° and -18°. I have very bad porpoising issues and after trying literally EVERYTHING to get rid of it (moving weight around from front to...

I had 2 very "healthy" friends sit in the front (at least 500lbs) and i got to 28mph before it started to porpoise. I also got 180lbs of plate weights and put the fuel tank (full 14 gallons) and 2 batteries in thefront and that didn't help either. I've moved weight all around the boat, installed...

Do you have any idea what degree of pitch the nozzle should be? When I first put it together a made everything level, so the pump nozzle itself was at 0° and having the trim nozzle gave me +15° and -18°. I'm thinking of making the pump nozzle -15° so with the trim nozzle I would range from 0° to...

Kinda to late to try that, already stripped it all down. I had posted on another site a while back when I first built the boat and no one suggested that. That was before I had found this site. Oh wwell, what's done is done... so since it's already stripped down do you think moving the engine...

Thinking about putting a spoon on my inboard jet Jon hull. Was wondering if someone could point me in the right direction for proper design? And also, I have a uhmw bottom, what material would yall suggest I make it out of that would adhere to the uhmw? I was thinking of trying to mold a piece...

It's very fun! Everyone told me to leave it like it was and just put a thottle stop on it and that 25mph was plenty but I couldn't do it! Knowing that I had 3/4s worth of unusable throttle killed me! I didn't think about trying to trim the ride plate down though. Everything is back out of it now...

I'm building a jet Jon using a 1652 flat bottom Jon boat and a 1996 kawasaki zxi1100 jet ski. I have already had everything together and had it on the water but it has porpoising issues. I tried moving weight to the front of the boat which caused it to cavitate and when i moved weight backwards...
