Hello experts-

Have a question/issue.

Motor is a 2008 Merc 90hp 2 stroke. It has a standard aluminum prop on it now. I have a stainless i would like to try out. Unfortunately, the thrust washers are different. The prop that is on it is almost hollow in the back and the front of the thrust washer that is inside the prop is very large....way too large for the ss prop that i want to put on it. The prop shaft diameter is the same on both props.

What i need is a link or a part number of the thrust washer i need. The ss prop part number is md13 1/4 x 17 lt. I think the prop shaft diameter is 20 mm and the recess where the thrust washer would slide into is 30mm. The inside of the back of the prop is 89 mm.

Any experts know the appropriate thrust washer....struggling to find any experts locally and its hard to search internet when they don't give the measurements.

Call the manufacturer of the stainless prop to find out what they suggest.
