So, February 25th we are having motors hung. I'm getting mixed recommendations on installing the wedges we have. I'm trying to find a downside to installing them??? I either need the extra trim or I dont right?

They are 1" thick at thickest point. No other distinguishing marks on them. They came with the boat but were not installed.

Yes on the wedges, 100%. No down side. When the weather turns snotty, you’ll be able to plane at a low speed. If that never happens, well great.

At this price, it’s a no brainer.

The lower unit will not tilt up as far. That's it.

I have the Bobs wedges on my Contender. Paired with the negative trim on the Suzuki my bow sits low without any tab.

The only down side would be if you keep the boat in the water and needed to clear the engines completely when moored. Go with the Bob's Machine wedges, they are excellent quality and a great value. I would mount the engines in the bottom hole (all the way up) as you gain setback with wedges since you need to trim more to gain neutral trim which due to the arc of the trim range, pushed the lower unit further from the boat. My buddy's Contender with the Verados has them all the way up and they could go higher, anti-vent plates are about 2.5" above the bottom.

Is there a rule of thumb on how much negative deg the outboards should be at? My nose is a bit light and i see i always have to have some down tab even tho outboard is negative trimmed up all the way.

Unless what sundancekid says is right and that particular year has a different transom on it than 31 opens around that same year.
I have a 2003 31' with F300 Yamahas. Do you think this setup will also benefit from wedges? What ywar is yours? Thanks

What is your minimum planning speed loaded? If it’s 16-18 knots with your current setup then it’s not worth it.

I can plane at about 13-14mph, motors tucked down, no tabs with our 02 31’ w/ wedges and 19p Rev 4s. Never tried with the tabs down, would imagine it may be a touch less but not sure.

I have a 2003 31' with F300 Yamahas also. Yes, you will benefit from them. I wish I would have gotten mine years sooner. Same with the 4-blade props.

I went from Yamaha F250 to Suzuki DF300AP on my Venture 34 and there where some issues to adress:
1° Your Contender will be most likely sternheavy due the added weight of the Suzuki's as you hull was designed for much lighter 2 strokes.
You can fix that with changes in weight distribution, move batteries to console or even more foreward, you may add drybags filled with lead to the anchor locker and she will ride much better
2° I tried 5 different propellers inclusing PowerTech OFS4, none of them run well till i gave up my stubbornnes and believed Mike from Outboard Specialities, installed Suzuki 16x18.5x3 old type with rubber hub and all went good
3° As SunDanceKid mentioned, if you add wedges the lower unit will probably be submerged, maybe also without weges and that's bad for moored boats. I installed Teleflex jackplates to fix that problem. Added weight forward helps also!
4° Your Suzukis will make you happy, and with the right prop you will enjoy your boat much more than before.

I ran wedges on a Hydra-Sports that ran a little bow high. Your boat is a little bow light boat - like many CCs and now with heavier engines a little negative engine trim will be helpful if not downright needed.
