Best Props for 35 Fountain???
 

Boat is a 1996 35 single step with 502 power. Performance report says they ran a 27. But should I be running a rounded ear or a more clever looking prop. I am running the round ear and with alot of trim I get a little over 5000 rpms.

My 2001 single step came with a hydro quad !Vs, 26s. I think it turned 4900.

What speeds were you seeing?

Your boat was most likely delivered and dialed in with semi-cleavers, Hydromotive props.

With the 502s, the Reggie report was 75. I never quite saw that number in real world application.

My 1999 with HP500's came with 28p QIV's,...but the boat also had factory-installed stellings ext. boxes. The "Reggie Propaganda Page" reported 85 mph @ 5350. I got about the same on good days. Carder

Do you still have same motors? Those are good speeds with 500s! Must be something to those extension boxes.

Tyler rebuilt both engines this winter, up to 585 hp and similar torque ft/lbs.... but I have had engines and drives grenading every time I get a chance to see what it is capable of running... I am thinking 91 to 93 with the upgrades and Julie dialing in the props... I am going out tonight to trial them.

Keep us posted. What broke on your last drive? And, you broke the drive trying to get on plane?

Bearings grenaded, but not getting up on plane. I was slowly testing at 3500, then 4000, then 4500... I stopped to inspect and the stbd. shut down. When I got it restarted there was a 'wurring" sound coming from the drive when I put it in gear... so I took it back to Tyler. Tomorrow he is reinstalling the drive. The props from Julie rocked up to the 4500 mark...
i am very curious what happens beyond that and will respond ASAP. Carder
