Got a 1995 232 with 454 Mag EFI. K&N Has the 320cc factory intake (Bad Choice by Merc.)
Turning a 21 pitch and 23 Pitch Mirage Hitting a miserable 57-59 by radar. I have heard exhaust will give you about 10 HP on a 454, Not worth $1800. Considering Vortec EFI Kit but not sure if it is worth anything. Also Seriously considering the Stern Jack.
The Rinker 236 hits 68 with 415HP and suposedly is the same hull?????
HELP!!!!!!
