Anything new on this? Very curious to hear what the top end will be on GPS.

We are delivering a new 353 with 525's and Stellings boxes. Ran it with 31" Hydromotives from my F-2 boat and hit 89.9 on the GPS on the rev limiters. Still tweaking and will report back with final results. Boat is VERY fast, though, and makes you pay attention!

Tom, my customer just ran 33 merc labs made from 34's,i/2 tank fuel,2 people,hot and humid Arkansas weather,86.2 GPS,we are getting there, the 5 blade Hydromotives Formula sent did not work well,not enough pitch.

TGC-32

Just tested the 353 with Merc 32" lab 4-bladers from my race boat, turning inward. 90.5 mph on the GPS heading east, 87.6 mph on the GPS heading west, for a two-way average of 89.05. I think the inward rotation gives a little more bow lift, freeing up the hull without having to trim so much. One engine still hits the rev limiter at times, but I think that this is about it speed-wise.

Try the inward rotation and see if it helps.

Regards,

Tom

Very impressive speeds

The Good Stuff:

Tabs are all the way up. You would be surprised at how much the drag of the trim tabs actually slows you down. Obviously, you need the right water conditions.

Drives are trimmed out to about nmber 7, but the trim scales on the indicators are unique to each boat so you have to do it by feel. Keep bumping the trim out while you are watching the GPS speedo.

I got my best results with 1/4 tank of fuel with just me in it, but the engines only have 5 or six hours and are still tight. We do have an agressive "X" dimesnsion, though. I asked the factory to set it up 1" higher than normal, figuring I could always space it back down if we were too high.

I do have to say that 90 MPH is probably faster than most pleasure boats should go. PLEASE PAY ATTENTION AT THESAE SPEEDS!

Good Stuff,I'm pretty sure your boat has the same aggresive X -dimension as Tom's boat,as you know it breaks loose getting on plane if you aren't careful,but once on plane it is pretty sweet. I still want you to try Dennis Cavanaugh's new Merc lab 5 blades when he has them ready at Merc Racing. Everybody is fighting for the first few sets,I have your name on a pair.Stay Tuned.
