I've got a 2004 yamaha 50trlc with original prop. I would like more top end and am curious about the proper way to upgrade the prop. Any tips or suggestions are appreciated.

You need to post your RPM and speed at WOT, and the type and pitch of what you are currently using.Stanley Islander 19, 2006 Yamaha F150TLRC. Ottawa, Canada

Not sure for any of that. It is however a stock prop. I know at wot I run about 36mph. Ive got a 16.5 duracraft alum. boat. Is there a way to find out my terminal hull speed? Curious about all this because I feel my boat should be running faster. I will repost as soon as I hook a tach up. Are there markings on my prop that inform me of size/pitch/etc?Comment

Termimal hull speed only applies to displacement hulls. Your speed sounds about right for a 50 on a 16.5 boat. My SS14 Grew runs 37.5 with a Pro-50.Stanley Islander 19, 2006 Yamaha F150TLRC. Ottawa, Canada

I am not sure why you expected to get 50MPH out of that set up, but look at this site and see what it shows for a set up like yours.
