    Default intake leak

    checking for leaks on the boat and i have found that at the rear of the intake piece there is some water coming on board. i think the previous owner knew that because there is silicone around it on the top side, and a very poor bondo job on the bottom. what would be the best sealer to use? the othet boat has some sort of epoxy around it.

    Hey Joe, put water in the bilge and crawl underneath you will see real qwik where the leak is. Then that will tell you the proper way or route to go about a repair. By the way I am not talking a cup of water, you need to sink the bitch on the trailer!!! Mark

    put the plug in and filled the boat with water. just till under the pump seal. i did this so i could check the transom adapter for leaks. successful on that. now to the next part. i seen a very small drip coming from inside the intake. got under there and it was coming from one of the grate bolts. someone ground the top off to the bolt is exposed and i assume they didnt put sealer on the threads. easy fix. then i seen some drips forming slowly where the green arrows are. all along the crack. i waited 2 minutes and finally a drop hit the ground. its slow but im aiming for water tight.

    ya, thats kinda how i feel about it. i want to get her up to par, but i have to fix one problem at a time. i wanted to do a set back this winter but some have said i dont have a great hull for speed since i have a deep entry on the front. that being said im in the ideas of just making this one water worthy and looking for a better design to spend my money on. i dont really know so i have to rely on what others share with me

    Joe! get under that thing with a jitter bug sander and clean that mess up! once you have it cleaned up and some what flat pick up some sea going epoxy putty and with your'e finger go around the intake where it mates to the hull. Make sure you get a good seal all the way around. Then take your'e finger and some water and form it to a nice seal. Now if you can get the intake grate bolts out take that rock grate and use it for an anchor, go buy a cheap loader with some good S/S allen head bolts toss in a tube of silicone and reassemble. It will come to life alittle and get you thu the summer. Mark

    Um I would sand the bondo off and see what it is hiding, then pull that intake and at least reseal it properly. The loader is the least of your worries!

    Reread his post! he wants to make changes after the boat season! I don;t think he wants to spend a month or two flipping the boat and so on! I was just giving advice to stop the leak and add a little get up a go-not rebuild a boat in July Mark

    Square. Set it straight down. Don't come in at an angle. You'll move the gaskets and smear the silicone. Good luck.

    this is great advice to get you thru summer, then this winter is your chance to pull the intake, get a shoe and rideplate and a good loader, reset and get to tuning the right way

    Yes Joe and when that time comes let me know. Square is not the proper way. Alot of angles go into how you set an intake. Alot goes into setting an intake, depth, angle, straight to the keel and chines, There are actually holes in the intake to set these items! Go back and look at the pictures of Joeys set-up and it will give you a clue on what it takes. His boat will be wet and tested before you are ready! Just enjoy the boat this summer and the get after it in the winter---any boat will run if you really know how to make it work and know the limits! Mark

    for a quicky seal job, I think a caulk like silicone 3M5200 would work best once cleaned up. If it's broken the seal, it's moving, since it's moving the little extra putty will never seal it.
