Better top speed prop for mariah Shabah 180
 

Hello - I just bought a Mariah Shabah 180 and my first time out on the water I was disappointed to see a top speed on my gps of 38 mph. The boat has a 14.5 x19 aluminum prop. I’ve looked around and I didn’t see what my top speed should be with the 4.3 merc but surely it’s higher than 38? 1200 ft elevation; smooth water and less than 500 lbs on board the boat. Any help would be great; I plan on getting smart tabs soon.

Read the educational STICKYS at the top of the Prop Talk section and all will be revealed.

And yes, Smart Tabs SX with a 60lb actuator arm will do wonders for your boats planing abilities.
