    Default Need a picture of a set back pump transom plate

    Mounting a Berk set back in my Alaska work skiff. I'm doing all the fab work here in CA before shipping everything up to AK for the install. It appears that making the 1/4" plate fit around the pump itself is pretty straight forward, I'm wondering however, how you seal up the area below where the plate mates up with the intake flange. Do you cut two small pieces of alum to fit into each side under the intake flange or what? Anyone have any pics?

    No two of these are exactly the same , depending on the hull they are typically made in two halves but can sometimes be made in one piece , suggest you mock them up with card board and carefull measurment first and get the edges that meet the jet suction body as close as possible , 100% silicone is typically used to seal them call if you have questions Tom

    Much like Tom said, I made a template. But I used a 1/4" masonite. After the perfect scribe, I used a jigsaw with a fine tooth blade to cut the aluminum plate. I continually cut into a bar of soap to keep the aluminum from packing itself in between the blade's teeth. Might be ghetto but it works very well.

    Damm! my pile looks super ghetto back then!

    I hadn't thought of splitting the plate vertically. I think I'll go that route as I can then address the area under the intake without having to deal with some little pieces of alum.

    I saw a post that some one used a welding rod and bent it to form around the pump.

    i like using the plastic for - sale type signs from homo deep, or dollar store to make the templates. cuts easy with scissors,retains its form, and when you get it wet it does not swell or anything,
    BOOBS; once you have seen one, you want to see em' all!

    I built some for my buddies 21 daytona split them down the middle. Pics are raw aluminum, he had the powdercoated to match hull. Just take your time on the templates and cut slow. I also used a rotor zip with metal cutting tip for the little areas.
