Hi,

I’m trying to find the best prop/pitch combination. I now have a 16” Dia x 16” pitch, 4 blade. That’s how the dealer set up my new motor when repowered. Motor is 2015 Merc 150 4S.

I’m getting 30-31 mph per gps @ 4800 rpm wot.

I checked Mercury prop calculator and came up with 14”- 15” pitch recommended.

Any different recommendations here please?

Thanks!

Hi Halibutt,

Our apologies for the delayed response. We have been having some issues with our email notifications from THT. Looks like you are definitely a little over propped with the 4 blade 16 X 16. If you wanted to stay with a 4 blade you could try the Rev 4 14 5/8 X 15.

The other option I would recommend trying would be a 3 blade Enertia 15 X 15. We actually have the Enertia 15 available to demo if you wanted to try one. Feel free to give us a shout at 941-748-1527 if you are interested!

Thanks!
