Default 1997 Contender 31 Open Repower...wedges?

All,

We are repowering to Suzuki 300's from 300 HPDI's. We have a set of wedges and are curious what others input is on their use.

Is it something we should put on? Boat is a little bow light when empty but most trips there is a couple hundred pounds of ice up front which makes a difference.

I appreciate any input.

I do not see a need. The Zukes seem to have more down trim the Yamahas. The uptilt stop is adjustable also.

A ‘97 should have the old transom with less angle, install wedges if that is the case. You will also have to remove the negative trim limit on the Suzuki’s to gain maximum tuck. My buddy actually upgraded his trim tabs from the Bennett’s to Lenco with the longer 4” stroke actuators and that made a tremendous difference in keeping the nose down, he has 300 Verados.

Someone I know has 31 contender with twins and he added wedges. He said it helped allot, without needing extra tab

I’d put them on if you have them. They work very well on our 31’, although we only have f250s

With that vintage boat, I'd put wedges AND 4 blade props.

Unless what sundancekid says is right and that particular year has a different transom on it than 31 opens around that same year.

So, I dont see where adding the wedges would have a negative effect. It could only be positive. The other question is props of course.

Yes. When you add wedges it brings the upper part of the engine bracket further aft, sometimes on some boats when the engines are tilted up the steering cylinders can hit the transom.

The zuke has a tilt adjustment to prevent that.

Absolutely, positively, 100%. Have you ever run out of upward trim range? Have you ever wished you could trim down more? One potential downside is that if you keep the boat in the water and wish to trim all the way up and out, you will lose a little at the top end of the range.

Yes on wedges. Ours is 5 degrees.

Props are Mercury enertia eco 3x16x20. Previously had Suzuki props, same size which were replaced after I spun one of them.The Mercury are way better. No need for 4 blades. Good luck.

I really appreciate the input. Looks like we will wedge. As for props they come with Suzuki and we can upgrade to 4 blade for $150 a prop.
Wonder if we can get a credit and purchase our own. It would be easiest obviously to just dial in with Zuke props if we can.

Boat performed well with the Zuke props, went with Mercury because of the replaceable insert. But now the zuke props have the replaceable inserts as well.

A lot of heavier boat were spinning Zuke hubs. I believe there were made by Solaris. They fixed that. Just make sure they give you the newer ones.

OP I would highly recommend you to stay away from the 15.25" diameter Zuke 4 blades. I have a pair I will sell you. They need a 16" diameter blade from my experience and from all I have read. The Zuke 3 blades have worked for many who did not need stern lift. I settled on PT LFS4 which is made for Zukes. Also the evo's work well I hear. If zukes I would agree the 3x16x20 would be a good start.

I have a 98 with 300 Zukes and wedges and definitely take advantage of the extra negative trim to tuck the bow when it is rough. There is little downside, you don't have to trim them down all the way if you don't want, but there are times it's nice to have them.

Also, the best props for me, running super heavy loads, often in rough seas, are Merc Bravo 22 4 blades. The boat runs much flatter between 15-30 mph.

Great info everyone. It's much appreciated. Looks like we are 2 weeks out from having them hung. What mounting hole are you contender owners of the same vintage using?
