GibSea 116 shaft diameter inquiry

[DufourDrifter]

I'm thinking about upgrading to a Maxprop for my Dufour GibSea 116, but I can't measure the shaft diameter right now. I looked online, but didn't find anythin. Does anyone know what the shaft diametre is for this model? I'd really appreciate any help

A direct measurement is the best way to go. Or you can try your luck with Dufour if they still keep all the data from Gibert Marine

It can be tricky as the exact shaft diameter may vary based on the original engine installation or any previous refits.
Have you tried reaching out to Dufour directly or a reputable parts suppliers specializing in older Dufour / Gibsea models?
You can also ask a local boatyard that services similar vessels.
They might have the information in their records or recognize the typical setup for that model.
Or they might be willing to measure it for you!
