Transom modification
Hi just to let you know what I did with the transom it has been raised 3 inches and replaced to fall with transom and has 3 x 3/4 plywood is fitted and knees put back and say I will have the right height to run twins it's a huge job to do this work Tony Davis extreme marine started the job with me but didn't finish so I have finished it myself and I can actually say I am very pleased with what I have done and will not break will put more pictures on when finished

Twin Motors
Interesting project..
whats the main reson for twin motors..?? i would assume for handling purposes what with L/H & R/H rotating props giving very minimal steering torque or are you just wanting big power, good speed with low revs..??
combined power of 400hp is massive for that size & weight of boat, there wont be many 21's in front of you thats for sure..!!
Keep us updated..
Cheers
Mark

Mike made several 400hp inboard 21D's
The engine well is a heavily bastardised version of the moulding made by Tony and I for my Extreme 24 OB (which has a pair of Brucato Promax 225s).

Thanks Lawrence the boat has come out really well
The engine well has come out ever so well it's a shame Tony didn't fit it like I did to your boat it really looks like it's supposed to be there here's a picture of how the 24 is done which is not up to my standards as it cracks in the corners on the last 24 I saw so I have made mine a proper fit not that the well is going to go anywhere as it is a very good design and very strong which Lawrence deserves the credit for as he designed and made the plug
