Mercruiser 5.7 260hp

[jrumon]

Alpha drive is a "weak link", but it CAN SURVIVE if you run it right. Merc used the Alpha with the hot 350/300HP Tempest (actually closer to 350hp), they also used it in 1986-1987 with the 454 mag (330hp) until the Bravo was finally released in 1988.

The keys to the Alpha surviving with more HP & Torque:
>running GOOD synthitic fluid in it...
>>run a drive shower to cool the upper gear set...
>>>making sure the outdrive is set up to proper specs (on the tight side to reduce gear lash)...
>>>>most importantly, not FREE-WHEELING it under full load (prop coming out of water and re-entering under full throttle load)... the Alpha tends to explode under harse load-unload-load conditions you can get in running a hot motor in a performance application.
