    Question Little set up help with efi

    In need of some help with a 2100 bumble bee and nothing going anymore in their forums. Having a hard time with bow lift on this boat. 01 super vee with 03 225 efi 25 torrent. Running about 3 inches under pad. 68/69 completely empty and one person only making 5600 at wot. Ran today after getting prop back from Mark. Bow lift still bad but hole shot and mid-range is awesome. Question is with this boat and motor is that the best top end I'll get with this setup and can I raise the motor to get the desired rpms I need (5800) and not lose what little bow lift I have? Water pressure is 25. Thanks in advance.

    For a TM type lower that sounds about 2” too low.

    I have no experience with that boat. I would think with that water pressure and rpm u could move it up some keep the pressure between 12-15 psi.
