Going from a 2013 GTR 35 on a 17/46Gatortail to the new 2015 18/48 & GTR 35 with the different lower unit and 3 blade prop. What changes should I expect?

Less chips in the paint job, and new stickers on the motor.

Bingo, and maybe a new payment.

I have same setup with a Mikuni and evt exhaust. I'm running about 31 light and 24 -26 loaded with 3 blade

3 people in deepwater up current.

Not bad, does the 3 blade shake bad like the old 2 blades?

Not even close. I have about 60 hrs on prop so I can turn it easier so I think that's why it's running wel with a load.

Nice, Thanks for the info.

Mine is an extreme hull. Is yours a standard or extreme?

ordered just another standard gator series

You might be a tad bit faster and haul a load slightly better. You should be well satisfied. This being my third mud boat and ny favorite.

I also switched to a tall transom, my 13' was a short transom and I did not like the short transom with the dropdeck, it cracked my plastic on the motor first stump I hit

About 4300ish with 3, 4100 with 5, and 4650 solo.

Now with the 5 only one was over 200# and the rest averaged 150#

That's on the second from the top pin. I actually need to move it up to the top hole. I run out of trim. It's not much more that's why I haven't moved it yet.
