2120 owners- what's your motor height?

[akholmes]

Hey guys
What bolt hole are your 150s hung at? I'm a 150hpdi hung on the second hole from the top. Thinking my motor is a little burried as I can only get 4800rpm on the 15x17p painted stainless stock prop and 5200 on a 15p mirage plus. Sea trialled a 15p 4 blade power tech today that took me back down to 4800 so I'm thinking the motor is burried.

Thanks for any input boys-
Spring is almost here for good!

Thanks Dale! I've read over that and did some searches on CP. I'm pretty sure I'm buried and just looking for some direct input from 2120 owners to give me and idea of how many holes to raise my motor.

I decided to raise the motor up to the top hole so far so good glad I did !

Different design/bladed/raked props run differently, so there's no universal answer for 2 like boats. But if I had to opine, most OBs are mounted way too deep from my experience and observations.
