Riva ride plate from Jims plate & lost speed. Advise!
Guys I took off my Jims closed loop plate and installed my Riva open loop plate. Well I went from 80.8 with full tank and 81.8 with 4 bars and now I am o nly hitting 77full and 78.5's with low fuel.
The handleing is great IMO, but I want the speed back.
I first had the wedge, but removed it. Seamed like to much.
Well any advise and help would be great as to get my speed back.

I changed mine out also (Jims skeg mod plat) - I'm at the same speed maybe + .5 (82+)
Maybe you picked up a boost leak

That is wierd. I know a lot of people that have gained 1-2mph by using the Riva plate instead. Maybe the angle of the plate needs to be work on a little more....

Unmodded Riva plate? I thought you had to tweak them some

I use to use Jims RP and my speed was 83.5, changed to Riva Plate and gain 1.5 mile
about loosing speed make sure from the silicon between the hull and the plate

Well guys I believe weather was close, but ofcoarse not sure. The boat always ran 81+ never a hecup until the riva plate.
I siliconed everything alot. I have changed a bunch of plates.
I did my first runs with the riva wedge. I then pulled it off to no wedge.
It is not shimed at all, but is rock solid and takes waves better imo.
Any help would be great. Would pictures help of install.

What year plate, and what year shoe is it on?
Also I run the wedge, and if u haven't already done so u will have to adjust your holeshot rod to get full up after install. Mine had a similar issue where It turned on a dime, but couldn't get the nose up much for speed, till I adjusted the VTS rod.
