Default Correct prop size for 3000 scr

I am sure this question has been asked... Does anyone know the correct prop size for a twin 4.3L on a 1998 Maxum 3000 SCR. I have to replace the aluminum props. One was chewed up pretty good. the other looks okay. Any advise would be helpful! Thanks in advance for your help!

Pascavone: Thanks for the link ... AND your honesty! :-) Happy boating! I haven't even taken delivery of it yet. It appears someone before me nicked a rock or something of the sort. The other prop is in great shape. Two of the blades are chipped and the other is scratched. They are the OEM aluminum props. I am thinking of replacing them with SS but not sure if it is worth the money at this point... I am not a performance guy and in no hurry to get anywhere!

welcome to the zoo....you can as stated pull the props and have them reconditioned in a prop shop......they can analyse the prop angles and tell you exactly what you have...if your just now purchasing the boat...you can put in the contract that either new props or the props have to be reconditioned...

Capt Jeff.......first welcome...........I hope for the sake of your bank account that you have had a surveyor with you to buy this boat and also get the lower units checked out.

So if all is good then the suveyor will take you out for a trial run but if you can't do this cause of the props being cut up....I would not buy this boat until new props are on the boat. The suveyor will tell you what size they are. Again your trial run you can do WOT and figure all this out if you what to use something different. Your boat with these V6's has a RPM range and that is what you have to be in between this RPM range. Not enough pitch or too much pitch in your props and the engines are not performing up to par.

I would think cause you have the V6's and not V8's that you also have the alpha drives and not the bravo drives. If you look into SS props for your alpha drives they are very reasonable for a pair.......however the bravo drives are not worth the cost for what you will achieve speed and performance wise again IMHO.

So things to think about Capt. protect that bank account of yours.

Thanks to all who replied. I am having new props put on it for sea trial. All has checked out so far... No issues with the engines and it has Bravo II Outdrives. The survey checks out good, just a few minor issues to deal with. Again, thanks to all!

Jeff

Bravo 2's on your boat with V6's? interesting!!

SS prop's for Bravo 2's are around $400 or $500 a piece and with those V6's you will not gain $800.00 worth of speed nor performance because of them. Save your money for gas and get the prop's redone by a good propshop in your area. Geez go check out the price of new aluminum props......that will pop your eyes out!

Good luck

Roger

Thanks guys! I found a very good prop repair shop just down the street from me. (So nice to live in the Tampa Bay area!) I will remove it and bring it to them for re-conditioning. I agree about the SS Prop... I am not a huge performance guy anyway and I am fine with the aluminum screws. I will post the Top End Speeds and RPM's once I get her splashed. I am (As with all new toys) looking forward to making her whole again and putting her in bristol condition. I'll try to post before and after pic's if I can get the picture function working on this site.
