So I finally got out on the water today. Life is busy and just couldn't get on the lake earlier. But i have my results for the 21p tempest and couldn't be happier. I installed VesselView Mobile and it recorded my best speed of 50.5 MPH at 6260 RPM. I calculated a prop slip of 3% which is kind of unheard of. Maybe the VesselView speed is off some? But either way im very happy with the boat. Did have some water in the bilge when plug was pulled out. Kind of suprised any water would come out.
Put a little bit of lube on the Oring of your drain plug and tighten it down real good. These plugs are prone to leak if not guddentight.
OK so how many with 115 c/t have had props switched to 21p?

I did, much better hole shot and gained a couple mph. Say something to your dealer, they should exchange it, 24p is the incorrect prop. You need your rpms up, mine maxed around 5200 or so with 24p.
Think what would happen in this country if the many stopped fearing the few.

Yep i was out on the lake Tuesday. Trying to get the fish figured out now . Havent fished the lake as much as i would like to.

14' Mirrorcraft tin boat (ancient) with a 9.9 Mercury 4-stroke, no electronics; catches fish anyway
So I wonder if Ranger will swap out my 24P tempest I had installed from them when I ordered my RT188 ProXS 115 CT. All I can get is around 5300rpm's and have hit a top speed of 49mph with wind at my back and going with the current on gps. I would like to put a 21p tempest on to get the rpm's up to 6000+ to keep my outboard from damaging itself.
Has anyone had a dealer that admitted to this mistake, putting the wrong prop on the boat. I also have the same 24P prop and motor combination and have always felt that it wasn't the correct prop. Just wondered if anyone had actually went to dealer and had them correct this issue by swapping props.
According to mine Ranger admitted they were using the wrong reference sheet. If this is a new 188 may want to wait a week or two in case any other common issues manifest and get it all done in one shot. Taillights burning out & motor trim pump, getting my pump replaced next week, this is the 3rd in two months. If motor starts drifting down it may have one of the bad batch of pumps installed. With that said, love the boat and no regrets.
Just talked to my dealer today. Says should have a 21p Tempest...... They gave me mine with a 24p ( what Ranger sent with the boat)....
So they are going to call Ranger to get me a 21p.

Make sure you guys are checking your torque on the prop nut. I noticed extra play the other day in my prop. I got my torque wrench out, set to 55 ft lbs and was abke to get TWO full turns on prop nut. The prop came from Ranger like this. Not sure how something like prop nut torque was messed up.
Called Ranger and they are sending me a Tempest 21p to exchange with my 24p. He said its the prop Mercury wants on it, but he thinks i will be just using more fuel and seeing the same top speed. So i wonder if the 24p is a better option?
