I have a 1996 29' Scarab that I purchased 2 years ago as a project and I'm only a few days from putting it in the water. The previous owner lost the fuel cap and there is a standard plumbing cap screwed into its place. Does anyone know where I can get a replacement? It seems to be an odd size.

you may need to get something machined

I also lost mine on my 1996 Scarab 29 and I believe I used a water fill deck cap. It screwed right on.

Hey I also live in Louisiana Metaire area, and have 29 Scarab. Check with Donavan Marine in Harahan they have the one for our boat I think. just out of curiosity are you going to join Gulf Coast Offshore boat club?
