I have recently purchased a staggered 377 scarab and am re rigging it with 540 ci Big blocks. Before i install the engines i am cleaning up the transom and was wondering if anyone has ever raised the TRS drives , how far, and what the results were? I will be keeping the TRS drives as i have plenty of parts to keep them alive for time to come. Any help , hints or suggestions for X dimension for a trs on this hull would be of great help.

If I were doing this I would raise the drives at least 2 inches I would need to know the original X dimension to give you an exact number Regards Dan

I know there are a few ways to measure x dimension, what way would you suggest to get the best measurement? My drives are currently off to be serviced and painted but the transom assemblies are still bolted to the transom

it makes it hard to measure with out the drives but if you are pulling the transom assy's off any ways you can measure off the bolt holes. Its a lot to type out how to do it but feel free to give me a call when you are ready Regards Dan 949-646-9778

It wouldn't take me long to throw a drive back on quick to get a good measurement. I just have to wait for the weather to break before i can do so haha. I just pulled the 540s out of the corner for rebuild and am getting anxious to re rig. I appreciate any and all suggestions

Dan i have a '97 thunder with Innovation 600's that i just measured the bullet on my Bravo's and they are 7'' below the hull line, does that seem crazy low or ?
should i be higher with something like a shorty Imco or sportmaster -2 ?

Shaggy I would for sure raise the X on your boat with a -2 inch drive lower. Wellcraft was very conservative with drive heights Regards Dan
