Converting from MercTrans to BW c72
 

I have a trs set up that had mertrans and am now soon to be ready to install the engines however have converted to bw c72's. I was told I need to move the engine mounts forward a couple of inches. Any insight on such would be greatly appreciated. I never gave this a thought throughout my project and am soon ready for installs. If it's just a matter of moving the forward mounts ahead I can't see this being a real big project however one that I didn't plan on. lol..
Thanks,

If I'm not mistaken the Merc Trans is 8-9" shorter overall. Beings their not in yet set the B-W next to the Merc Trans and line up the tailstocks where they plug into the transom plate. Then measure the difference between the 2 where the engine bolts up to the bell housings.

Assume you changed your input shafts on your drives also.

I will measure them up today. Haven't changed the shafts out yet either. I may see just how much power the MercTrans will take. All the years boating this is the first TRS project and am learning something new every day. lol....

also make sure you have a merc trs aleignment tool handy..

Thanks guys. I measured them today and was a little surprized how much longer of a set up these are. I guess when I was looking at them from time to time in the shop I only paid attention to the BW minus the tail. The merctrans measures close to 15 1/2" and the BW with housing and tailshaft is close to 21 3/4".

I may be out there on this one however with moving the engines that much futher forward, will this change the handling etc. Given that everything originally (x-dim, drive height, etc was based on the weight where it "use to be"?

Or will the difference not be enough to be concerned with?
Thanks,
