    Default Is this a crack?

    I am having a hard time deciding if this is a crack or not. My first thought is that it is a crack. The more I look at it I think it may be a grind mark from when the intake was set. This is a 21' Daytona with a full set back pump. I tried using a .006 feeler gauge to determine if it is a crack but it will not go. There is no evidence underneath the boat to indicate it is a crack. That brings the next question, If it is a crack and it does not extend all the way through, could it just a superficial crack in the extra resin that collected in that area durring layup?

    It is for sure a crack!! but it looks to be just in the resin, but if it was me,I would grind it out and see just how far it goes, and then fix it! Just my,02!!

    No evidence of a crack at all on the bottom/outside of the boat in this area. It is only visible from the top. I will get a pic of the bottom later today.

    Thats what it looks like to me. IMO, would just leave it unless you plan to pull the intake. But it looks like you could almost hit it with a chisel and that piece would chunk out. But if it bothers you, I think I would take an angle grinder to it and see what it is with intake still in.

    There lies the problem. It is tight back there. I see no way to get in there and grind on it without pulling the intake. I also see no easy way to pull the intake without puling the motor.

    I cleaned up the outside tonight. There were/are various layers of silicone, some other kind of sticky ass clear sealant, poxy putty and what appears to be JB weld from previous attempts to seal the intake. At this point I think I am going to take it to a professional for an intake reset and let them look it. There is no doubt the intake could stand to be reset just by the condition of the poxy putty. I tried to get a picture but there is so much white you can't see anything but glare. I did look it over very well. There is no evidence of the crack on the outside of the hull in any way shape or form.

    Looking at it again with more info, might be a bad fix it job with out pulling the intake. Also missing a nut and bolt. You will have to pull the motor to pull intake, clean it up in there and reset. Good idea to install a pump brace inside and out with a set back pump for support. You will sleep better at night when done.

    Agreed. There is an outside brace but no inside brace. I have a feeling it is related to trailering the boat. There is a lot of weight hanging out past the transom with no support when the boat is bouncing down the road loaded on the trailer. The external bracing for the pump will keep it from pushing up or forward but it is no real help supporting the pump being pulled down or backward.

    Its a crack. Lots of boats with full setbacks crack in that area because of the lack of support. Not a big deal, do get it fixed. Take out the intake add glass to that area. Reinstall intake and add inside pump braces to minimize future cracking. Yep I know a pita. Went through this on my 21 already, actually most boats with full setbacks are prone to this.

    Yes it is a crack and should be fixed. The silicone and J-B weld you found tell you that someone else has already been fighting a problem there. Lots of good advise above; reset, pump braces, etc. Also Be sure to get rid of any traces of silicone before resetting the intake.

    Has someone alredy tried to glass the area or is that the original layup. What kind of boat is this?

    Thanks Duane. Will do.

    Feel free to post pics of pump braces on 21' Daytonas. I need some ideas.
