500 EFI to a 525 EFI
 

Has anyone done the retro-fit from a 500 EFI to a 525 EFI. I am curious if there is a noticable difference. With a 25 hp increase..I would not think much difference for the $$$ investment

I dunno who would do that. It requires an entirely different ECU.

What I have heard is the Arizona Speed people stated you change the throat portion and something else. I think I will try to look it up on their web-page

Went to AS&M web site..could not find anything

Elkton, MD....was near there last fall checking out places to launch.....NorthEast and Port Deposit

I have looked into it also, the AS&M kit I think is around $800-1000. Not too bad for 5% increase in power. I think with the right prop looking at a 1-2 mph increase fro single engine boat.;) If I add one it won't be until winter, the summer has started for me, no more work just play now. Maybe come fall we can get an OSO discount going if we order 10 or more at once.

WILL:cool:

Or maybe 5 or more...I'll do 2
