1996 Stepped 35 screw in or out
 
I have a 96 35 foot with M4 Procharged 540's XR drives turning 34 bravo ones screwing out, the current power has been in the boat for about 10 years and I have it apart for repairs the two major issues are, the boat gets a lot of tail lift at WOT runs high 110-120 depending on conditions about the only thing in the water is the props, second and worse problem it spreads the drives pushing them outward and eventually it breaks the transom assembly and breaks the guide off drive housing, I have it apart now installing new HP transom assemblies and I was wondering any experience first hand on screwing them in versus out.

IN is what most run, R3 has always stated IN as well.

I remember when I did Dan Jones 42 (Prochargers Boat) I screwed them in but that was a long time ago and I haven't done this for a living for a long time and cant really remember the different characteristics this 35 I have put various combinations in it since it was a year old but have always ran it out.

it to win!!! That is what I've always heard. Has proven true in my case.

Maybe consider dual tie bars and look for worn steering parts as well.

UMM you were running standard Bravo transom assemblies for 10 years while making enough power to run nearly 120 in a single step 35 fountain??? AND standard Bravo lowers??? I have a VERY hard time believing this? What is the sorcery behind getting this boat to 120 with B1's????

This will be the third transom assemblies and 3 XR drives to date, and probably 6-7 regular bravos. In August of 2000 I did a similar set up that was on the Cover of Hot Boat Magazine on mild 502 bottom ends with M4 Prochargers in ATI's (Prochargers) 42 Fountain I used Stuart Van Dynes Dyno for a independent result and made just over 1000HP. That 42 ran 109 for the test with Wilks driving, we had had it faster but just the way the numbers ran that day. On this 35 the engines are a bit wilder 540's JE pistons Gapless rings H beam Rods Solid Roller cams Edelbrock heads using Edelbrock tunnel rams and dual carbs and M4 head unit (if you ever run across a M4 set up on a tunnel ram its from my shop) We had a similar set up funning in my friend Steve's (Founder of HTM) personal HTM SS that ran 153 and my HTM with a 614ci M4 (BMax) running 160's My name is Jeff Clark I owned Clarks Performance Marine in Havasu hence username CPM there were plenty of articles in Hot Boat of the things we were doing in the late 90's early 2000's

My non-step 35 with b1's would last just hours before the gears would break running in the low 90's
