Flush muff brand for Honda bf15d bf20d

[Hotmath]

I bought a west marine rectangular flush muff but it did not fit the water intakes at all for my motor. Is there an an available one that will work for my BF15d, or is there a work-around to customize my muffs?

Take a measurement of the intake screen and go shopping. I have a round set that works for my 90hp Suzuki but are too small for my 9.9hp Honda.

I did that, the muffs I bought fit over the intake ports fine, the main problem is that the surface around them is not flat. Maybe I can heat them up and reform to my topography.

Or maybe make a spongy, waterproof gasket?

Or use a barrel or whatever, works way better if it’s an option.
