    Alpha 1 upper destroyed

    Its not under warranty. I confirmed with SEI that the lower that is on my original Mercruiser with the wrong upper gears will bolt right onto the Upper they sell with the gears that worked great with my setup. The prior owner purchased the SEI drive lower and upper way beyond the 3 years they...

    Alpha 1 upper destroyed

    WOT trimmed properly I was in the 4600 rpm range with the 1.81 SEI drive and I am not sure what Pitch prop that was running but I still have that prop so I can check. The paperwork I have says the motor is 160HP Serial # 2233574 Chevy Straight 6... 250 Cubic Inch. I also need to get the...

    Alpha 1 upper destroyed

    I really like the Hull design and the Carolina flair. You can see the SEI drive there and that was a 1.81 so its really odd that 1.65.1 is what you are saying and what I saw for an inline 6. I think I read that SEI gears are different somehow. Yes it was converted over to Alpha 1 Gen 1. I...

    Alpha 1 upper destroyed

    Alpha 1 upper destroyed

    Alternative to the above also seems to be that I change the gears in the Alpha 1 drive I have bolted up now... or possibly take the Mercruiser Alpha 1 lower from and bolt it to the SEI upper... if that is even a possibility.

    Alpha 1 upper destroyed

    I purchased a new SEI upper and lower and last year because of the o-ring not being where it should have been after servicing I was cruising along and the upper gears shredded. As soon as I heard it I immediately shut down and got towed in. I since have been using another original Alpha 1 with...
