Zodiac Futura mk2c/Yamaha 30hp prop selection

Hi, I've got a Zodiac Futura mk2c with a 2st Yamaha 30hp 3 cyl that I picked up last year. Needs a bit of work regluing etc so no surprise there. It's fitted with a 9 7/8" x 13" ally prop which just seems really small, certainly in comparison to my Mariner 25hp 2st. I'm just wondering if anyone else has the same set up and if so what props are you running and what performance do you get?
Thanks in advance.
I'm sure this question has been posted many times before but I couldn't find anything.

The glue fails on the bottom and transom, but the tubes are thermo-welded and do not fail. The bottom of the boat and all strips will need to be removed and reglued, along with the transom. It is a big job.

Prop choice has so many variables. Like I ran heavy for scuba diving so my prop was more for hole shot. Once you get the boat back on the water let us know how the current prop does. I would recommend getting a tachometer so you can see RPM which will help you get the right prop.

Thanks Peter, the gluing is just one side of the transom, the port side looks absolutely solid. I had the same issue on my bombard aerotec so know what a big job it is as you said.
Hoping to be on the water next month but was just trying to get a feel for what people are running prop wise. The 9 7/8"x13" looks to be the biggest prop for the engine but it just small next my mariner.
I've ordered a solas 10"x14" stainless so hopefully will be able to let you know how it goes.

I'm guessing 2002 if the boat was originally bought with the engine as I know the engine is 2002. Is the manufacture date on the plate? I'll check later. I'll try and add some pictures later.

If it is anywhere over 15 years old or even 10 years old, all the glue is failing. Try pulling up other areas of the boat with the thought you are going to be taking it all apart. This is a well known issue with Zodiacs. If you repair one side, it will be the other side next. Then the floor. Fix it right and it will go another 10+ years. Probably not what you want to hear, but that is the reality. SIB transoms get kicked hard by the outboard, and failure on the ocean does not sound like a good outing to me.

There should be a plate in the insideof the transom and the last two numbers indicate the year of manufacture.

Thanks Monkey, I guessed one of the plates would give that info. The plate on the inside that gives capacity etc. the Serial ends in 15 unlikely that it's only 5 years old but the plate on the outside of the transom ends in 04. Given that the engine may have sat 'in stock' or been purchased separately I'm guessing is more likely to be 16 years old.
