Ranger rt178
Anyone out there have a rt178 with a 25 hp etec? I know i know way underpowered but where im at its all hp restricted lakes. What prop are you running? What is your top speed? Looking to get as fast as i can. Think of it as a restrictor plate NASCAR race every tiny bit helps I'm currently running the factory 12 pitch Evinrude prop. I'm only running 4900 RPMs so I needed to drop pitch to get those up and 20 miles per hour top speed with two guys and tournament loadout any suggestions are welcome.

Maybe raise the motor? What hole is it mounted in?

[Pitchn]

Mounted in second hole anti cav plate level with hull

I forgot to mention it came with a static 4" setback jackplate

With a jp it's to low. Try lifting motor up 1 hole and see what that does.
I have a 6" jp and I'm at 4-3/4" (centered prop to bottom of keel). You should be anywhere at 5" to 5-1/2" with a 4" jp.
Evinrude aluminum props flex a lot. Since your needing a good pushing prop. Try the SSP.

How does she run with the 25hp? I am not much of a speedster and the price between a 25 and a 70, 90 or 115 is significant.

20 mph with 2 guys and a tourney loadout...24ish by myself....an etec is super helpful my buddy has same boat with a yammy and gets 16ish

Oh I only wish you could put a 90 or 115 on a 178.

That's pretty decent for a 25!

75 & 90 hp Etec are basically the same motor. Both put out about 82 hp
If you are going Etec the 75 is a good choice for this boat. Also Etec now has a 60 hp HO that is the same I3 power head.

I have a RT 178 with a 2018 Etec 75 with a 13.5x15 3 blade aluminum. I drove 2.5 hrs one way to pick this boat up , got there and it wasn't ready for me . So I waited patiently . Took the boat home only to find it will not Rev over 2000 RPMs.
