I had them in my Motion. I will save you some money as you WILL BLOW THEM up if they are not center aligned. The crank must be perfectly centered with the bellhousing or the trans pump will go boom. We used offset dowel pins (Jegs sell them) to line up the crankshaft to the bellhousing. This is a must do. Ateco Engines used some tool to do this. I watched it only took a few minutes. I found out hard way twice.....

No. Special built transmissions built to handle 1200 + HP and take the abuse of a heavy 46 in 3 to 4 to 5 footers in and out of the water. They were built to fit in the same place as bam or hubers. Bam builds a great transmission but I couldn't get them to live with the abuse I gave them. I don't know anything about your B&Ms. Good luck.

To the experts...
I just happen to be going through this now as I have an old 12 meter with two speeds, the motors are out but want to put it back together right the first time...
Quick question... Once the transmission is centered on the bell housing, I should be good to go. I don't see a need to remove the tranny from the bell housing so I should be able to just bolt them back to the block. Correct? Or should center be checked when removed from the block? The boat ran a few years with these trannies already and don't want to mess with them if I don't have to.

Can anyone point me to any articles/pictures on B&M 2 speed marine transmissions? I just bought 3 of them and am looking for information on how they were coupled to the flywheel. If anyone knows where there are any couplers lying around for these transmissions I would appreciate a helping hand. Thanks for any help.
