I have a 1978 Starcraft Islander 22' with a Mercruiser 4cyl 120hp I need to replace the prop.
Most of the numbers were corroded and I was not able to read them. Does anyone know what prop this takes ?

Thank you

Are you looking for the pitch? What is the RPM range for this motor, do you know?

I do not know the rpm range, just want the stock replacement prop I have no idea what I have. When I go on Iboats to choose one it asks
for the pitch. So I probably need to find a way to measure the existing pitch on my curent prop.

Thank you

Yes if you like the hole shot and top speed then replace it directly. If you want to make some changes, well that is another story....

Look under the prop nut for numbers.
Do you have the present wot rpm and speed?
A prop shop can measure it for you and may be able to repair it
if cost effective.
If I had to guess( not reccomended) for a prop it would be a 17"
