Default 06 620 4 blade decision. Numbers inside.

Hi Guys,

I recently bought a 2006 Ranger 620VS with a 2006 200 Opti with 162 hours. The boat actually performs surprisingly well and puts down similar numbers to a lot of the 620s with 250s from that year range. Currently it has a 21P Tempest and will turn it with a light load to 58MPH and 5600 RPM. Hole shot is very good. I would like to bring the RPMs up near max with a light load and also move to a 4 blade. I want the boat to perform the best that it can all around. I am looking for opinions on running either a 19P Rev 4 or a 21P Bravo FS. I have run Rev 4s in the past and like them very much. I hear great things about the Bravo FS. (especially on this hull) Which would you choose and why?

Thanks!

-Eli

I don't have that boat but from what I've read you're supposed to go up one inch to a 22p bravo FS when you change from a tempest prop. I went from a tempest 19 to an FS 20 and it worked good on my boat

Back in 2006 Bass and Walleye magazine did some interesting tests on 250hp motors and all were on Ranger 620. I can't find the article but this thread might get you going in the right direction

Thanks PJ. I have read the article before. The problem is, neither of the props I mentioned were in existence back in 06.

Northwoods.... I need to gain some RPM. Hence the 21 Bravo.

The prop they ran was a lab finish Bravo and if memory serves me right it was 23 or 24 pitch prop. The fuel economy was performance was outstanding on the Opti and that is what stuck in my head. The 2006 hull was defiantly faster then the 2008 and newer hulls because of the added dead rise.

I got some more baseline numbers last night. With 51 gallons of fuel, full cooler, all our gear and two people it ran 54.9 @ 5430 RPM. I think I am going to give Ricky a call and demo a 19P Rev 4 and a 21P Bravo 1 LT.

I think you should try the Bravo 1 FS with that particular hull.

Thanks Roger. I am open to any suggestions. What is your reasoning for the FS over the LT? The longer tube on the LT should provide more stern lift than the FS.

The 06 to mid 08 620 hull is a much sleeker and faster hull than the previous and the newer 620's, more "Triton-esque" if you will. According to Scott at Merc Racing the FS is better suited than the LT with that type of hull. You can always try them both, but I'm guessing the FS will be faster on that boat.

I don't have the 620 but I can weigh in on the Rev 4 and the Bravo FS. I had a 19p Rev 4 on my Warrior with the 200 hpdi. I have been happy with it for the last two years but it was just a pinch bit too much prop. I like to perfect things and had been thinking about trying a Bravo FS 20p since it is suppose to be easier to turn. Well finally last week I gave Ricky at Brainerd Props a call and had the Bravo 2 days later. I just got back from three days at the river testing it. I like it. I ran it first with the solid PVS plugs out and then with them in and didn't really notice much difference it planes out good either way. Top speed wise the weekend before was 46-47 mph and this weekend was 48-49 with the same people and load in the boat. I did hit 50-51 by myself. I do think it does spin easier, and has about as much bite as the Rev 4 but not quite as much. We fished some windy 15-20 mph stuff on the river so I got to test it in semi rough water and thought it did well.

Now for the bad part......I have to call Ricky tomorrow and tell him I am going to keep it and that is going to cost me $$$

Nothing against the Rev 4 it's an awesome prop but I feel the Bravo 1 fits a niche
