Thinking about adding a tower to my 2400 TRS

Recommended Posts

I have a 2019 2400 TRS powered with a 250 SHO, I'm thinking of removing the hard t-top and adding a tower. Anybody have a newer 2400 TRS set up with a tower,  just wondering how it affected the performance, speed, fuel economy, any porpoising issues? I'm running an OFX19 4 blade prop and getting 5700 rpms and 50.5 mph WOT. My dealer mentioned it may porpoise with a tower, any feedback is appreciated. Didn't know where I could post this, so I hope this is the right forum, thanks.

I have a 2018 24' with a Yamaha 300hp  and had Quality T top fabricate an aluminum 3/4 tower and upper helm.  After trying the boat out it did have a tendency to ride nose high with some porpoising.  I installed a 5 degree negative wedge between the jack plate and motor which resolved alot of the flipper problem.  The aluminum tower is a lot lighter than the factory fiberglass one  but is a little heavier than most T tops.  There is also a little more drag.  Right now we are trying several prop sizes trying to get the most out of it!

What kind of numbers RPM vs MPH,  Top end? What kind of tower  do you have?  Ive been testing several 15 1/4 dia and did ok with the 19 pitch but could only reach 5500. Yamaha wants to see 5800-5900 with that I was getting 51 mph. I tried the 18 and started losing grip.  The 151/4 x 21 that came with the boat was way too much resulting in a horrible hole shot and only got to 5000rpm.   The prop I like the best so far was a 4 blade turbo OS-1 141/2"x17   The hole shot was great top end at 5800 was 51mph plus it gave me a little stern lift!

I’m running around 5600 and 53ish with a moderate load, trimmed up and also jack place up a few inches. 

 

Sounds like you found a nice prop. I’m also leaning towards trying out the Q4 19P.  My hileshot most get better.
