i have a 94 f150 with a standard 300 and i tow my boat around all the time with no problem..now i dont hound on it and slap on a huge boat mine is (a heavy)..15 ft fiberglass boat with a 40 horse mariner..so nothing to brag about..but i do great... i also haul a lot of wood..and it does fine with that as well..but if you really want the best.Id go with the new intake/exhaust..(the two work together pretty well)..and that should boost it up enough..if not maybe you need to get the right truck for the job...
