I have an a 1988 Scarab 28 foot I think it’s an Excel what’s the boat used has a bravo drive Xr1 With a 454 magnum engine never had the boat in the water my garage burnt down the prop was in the garage and I don’t know what to put on the boat it’s 15 spline any information would be helpful please I know this isn’t the correct drive and I would really like to get it together

XR's have a 1.25" prop shaft. So you need an XR insert for whatever prop you plan on using.

i count 15 spline does that sound right. how would i go about finding the correct prop and pitch and where to get them
