Picking motors back up on Saturday. Ended up doing a semi dry exhaust as we found a milk shake in the bad motor. Not sure if it was due to the lifter taking a dump or not, but we didn't want any reversion issues so motors will now be dumping most of the water through the transom. It's been a longgggg winter!!!

Yes, alot has changed in a year
. We ran 71 mph gps with the new 600hp mills. I was running two left trs drives, and the motors performed perfectly all season! We did end up doing a full dry exhaust as any moisture in the pipes at all caused severe reversion. We Also updated both motors to new full hydraulic rollers, with the proper valve springs as well. (let's just say what was in there was not exactly kosher) We also did some port work to the heads. Everything was re assembled with the proper parts to add blowers down the road. The motors are now back out, as I just finished putting big shaft #4's on boxes with full hydraulic steering, huber 1350's where also added in prep for some big power. Hope to run in the mid to upper 70's this season with the surface drives, rather than dragging those deep deep trs's through the water. Next winter it's blower time, looking for 800-900hp per side. I have some pretty exciting ideas we will be devolping to make the power. Let's just say they will be unique mills.
