I have a very well used 14.5' Astroglass bass boat with a 40HP outboard. It has no tilt or trim other than a manual position setting for the outboard which I set for an average tilt. It suffered to get on plane with two people and never got on plane with three people. I purchased the Sting Ray hydrofoil classic. $50.00
This was amazing It popped right up on plane immediately with one two or three people.
Simple installation took less than 20 minutes to install.
Good luck!
