How does your boat get on plane with that x dimension and what size props and how many blades? I'm running a triple setup that was originally 16.5 x dimension and i'm now running -3 imco's putting my x at 19 1/2...running 31 pitch 6 blade herrings and my shaft is about 2 inches below the bottom of the hull. I need about 4500 rpm's to get on plane.

Hey 47 lightning , with the other engines I was running 32 15.5 hering 5 bladdes it took about 2800 to get on plane slowly you had to let it do its own thing , the maximus props worked a little better and better cruise rpms in the mid range,now with these engines all I have right now are some stock 35 maximus props which are going to be my spares and these are a little to big or grab to much water , still waiting on my new herings , supposed to be sent out wed 15.5 33 6 blade with the thicker ears for more strength as per jeff at hering , we will see.

TRL just wondering how much they are going to raise the starboard engine with having the whipples and interfearing with the engine compartment gunnel. I have the 4.0 whipples and the moac coolers and I moved the starboard engine 6.5 inches forward otherwise I would have to a major part of the gunnel out for clearence .
