    Default Repairing intake fins

    Working on our eliminator and just wondering how do you go about repairing these? They are cast aluminum and pretty beat up so can I weld another piece on it and shape it or is there another way to repair these?

    Take a picture Brad. If its not to bad you can reshape them or cut them down. You can weld them up, but i wouldnt suggest doing that in the boat.

    The fin on the drivers side of the intake on my boat has about two to three inches that have been broken off. Looks like one of the previous owners simply reshaped it, and let it bump. It has not seemed to negatively impact the loading, handling, performance of the boat, just ugly when you see them not matching when you look underneath the boat.

    you can see in the front where its been broken on both sides then repaired. i dont know if you can still repair the one side by grinding and reshaping but if your guys still think i can then ill go that route

    Grind them both flat and see what that does for the boat.

    Default ouch

    might want to check the trailer first. Are the bunks too low causing it to drag across the rear frame member on shallow ramps?

    Some boats the fins have no discernable effect at all(think "E" pump- NO FINS), others will have load issues, especially in the corners, the higher the Horsepower usally determines the grief, as does hull design. I have a bunch of the intakes for sale cheap! TIMINATOR

    I found that the fins created more turbulence/cavitation when making extremely tight corners on my V-hull. Those tight corners are nearly impossible on the tunnel, which makes me wonder about the necessity of fins to maintain tracking on the tunnel? Food for thought.
