    Does anyone know what size trim tabs on a 1983 3870 are?

    Stock trim tab size on a 1983 3870, I forgot to measure mine, I have some electrolalis on my port side from a previous neighbor who has since moved, the boat sat for 4 years and not moved.
    Cost more to weld it than a new on I think.

    Is that the year they were two tone beige? There is a fair representation of 38xx’s, along with mine, at Dagmar’s in Everett, WA. I plan to go work on the boat tomorrow and can measure that one and/or mine, a 1988. If I don’t get shore leave from the Admiral for tomorrow, it will be Tuesday.

        Same on most all of them 11” front to back, 18” wide, wings are 3”. And, I took pictures! Using an iPad to take pictures one handed is a pita.

          Looks like they are what we call 18 x 12 with Drop Fins, part number for a new Tab and Hinge Plates is TPA1812DF.

            Thank you, they want more to weld it than a new one.
