Bob, would a 500 hp fit right in where a 496 was in a 280?/
PKS, you mention PQs like to have a shorter outdrive...how so and what is best??

PQ mounts the out drives deeper because it is a pleasure boats and makes it easy to get on plane. Basically what you are doing when you go with a shorty is raise the X dimension, the measurement of where the prop is in reference to the bottom of the hull, the V part. (someone correct me if I'm a little off)

Bob, do you have any performance goodies left over from the powerquest?? Would a good set of tube headers and a re -program be worth the money and effort for the performance that would be gained??

Thanks,
mike

A good pair of CMI headers are the best thing you can bolt onto an engine, getting the exhaust out quicker will make the engine essentially more efficient.

Thanks PKS....cmi headers would look cool too....Maybe I should hold out for a 500 hp or put in a Raylar kit......dunno!!:cool-smiley-027:

Verbi69,Changing from a 496 to an hp could be a lot of work.I would stick with what I know fits and work with Raylar.I'm sure they can make enough power to get your attention.CMIs look bad and sound great,not to mention they work.They came on my HP500 so I kept 'em for my 548.Bob

a 270 and 280 have different hulls, not sure why the comparison. The 270 has a low X and the 280 has a much higher X due to the step and the notch. The previous owner added a 1" spacer to mine and picked up a couple mph. I see 69.5 gps all day with a slightly modified 502.
