Reccommended WOT for 115 Johnson

[aanda6]

Hi, I am waiting on a manual to be delivered, so thought would ask the question now to save some time. What is the reccommended WOT RPM for a 1977 115hp johnson. I have it on a 14ft swifcraft used for skiing and need a new prop and want to work out the best size and pitch for my setup.

Your target rpm with an average load is going to be 5800. Whatever prop gets you there, you will probably want a smaller pitch one for skiing. That way it wont be hard on the motor or the skier.

Thanks for the quick reply. I have been looking at a 15 pitch 4 blade ss from solas. $790AU . unfortunately everything costs more downunder. Most parts I get shipped from the states but not sure if it is worth it with a prop.
