Prop selection for 90hp outboard.

[mruocco]

I finally got an old 1980 90HP inline 6 running thanks to all the help this community has given me!!

The prop thats on it is pretty beaten up, and I am considering getting a new one but do not know what pitch I would need. Here is some relevant information:

Its a 90HP outboard
It's on a 16ft bayliner capri.
The boat will likely be used for mixed purposes. Pulling kids on tube, crabbing/fishing, just cruising, etc.

Any insight would be greatly appreciated.

Look at the numbers on the prop you have now. Order the same thing.

What are your rpms with the prop you have.

The WOT RPM range for the inline 6 90hp is 4500 - 5000. Engine makes its best power between 4700 - 4800 rpm with a sharp drop off in power above 5000 rpm.
A 17" on that combo should put you near the sweet area. Probably that's what is currently on it now
