Once again thanks for all of the responses. Can I put 5's on without boxes? Or would that put them up too high?

Sometimes I think we should just leave well enough alone, unfortunately this is all excess for excess sake. Gotta love it. I just want to get to the point where it makes noise again.


I am about to buy a 10k Sea Ray just to go boating..... I may also be getting a divorce with that 3rd boat.

Ironman. The fives work better with a box . The alternative is put a notch in the hull which is what I did . I am a do it yourself I have a thread on it titled “ how to put a notch in a flat deck “ pretty original eh! It was cheaper for me to put the notch than buy all the box parts . Enjoy amigo . Rick

Bruce would kill me at this point if I had him notch the boat after we just finished the entire engine bay. New transom, reinforced the bottom, stringer reinforcement all ground and ready for gel......

6" shorter

If it was me with 700-800 HP, stay with SSMIII or IIIA, 6's are tough but do still break and they are expensive to fix, 5's and even 4's would easily do the trick, but will need boxes.I thought about putting 4's and boxes on my gun this winetr with the parts I had here, veterans said at 800HP and under its not worth the hassle vs what you lose. In Lake Erie with that boat I think the speed gains of moving with that power will not be worth it to make the planing and rough water bite loss worth it, just my opinion. I been watching Frick battle this, Dan batte it, and even Cigrockets old boat is local does alot blowing out getting on plane. Brian Snyders boat at 80 with deep 3's is a BEAST in bigger and sloppy water, some boats like deeper drives even thought speed is not there, I learned if you want fast, go buy a Fountain, solid rough water keep the cig

Here is a couple charts to look at

Hey Tim would mind emailing those charts to me they Are way cool . My email is [email protected] . Thanks
As for the box question , as I said earlier I put a notch and put 5 drives on my flat deck . I currently have 3 inches of spacers and the prop shaft is 2 & 1/2 below bottom . The boat planes at 3000 rpms in about 2 minutes or so . This summer I am going to take out 1 inch of spacers and see if I can a bit more speed without any loss to planing .
