hi guys how do i tell what drive i have on my boat it has SE106 on the leg

[aussie]

ok i found out of google its a alpha 1 seems like theres different ratios and hp rating as well as max rpm

[THEFERMANATOR]

SE106 is a STERNDRIVE ENGINEERING aftermarket replacement for an ALPHA 1 early style(90-).

ok thanks ferm can u tell me a little info on these are they any good and what about ratios could this be one of the reasons my boat was under powered did they put the wrong ratio in it omg now i will have more head aches HELPPPPPPPPPPPPPPPPPPPPPPPPPPPP

Your gonna have to look it over as the upper should have the gear ratio stamped on it somewhere I believe(spare will know better than me on this one though). They make a good quality product for a fraction of the OEM units. Only complaints I have heard of have been a few with gear noise due to improper break in, and some paint issues(the paint problem was only on the early ones).

The sterndrive engineering outdrives are as good as the OEM, so your good to a 300HP small block with it. HP isn't the killer of them though, torque is. I seriously doubt that a 3.7L can make enough torque to hurt one.
