Motor is brand new in 2003, Bravo drive, 23 pitch prop. <br /><br />Had the boat out twice last week on the bay and all way great. Took it to the lake Sat and it now seems as if it is running at about 3/4 throttle. My hole shot is crap. Takes 30 second to get on plane and once on plane I have lost about 3-500 RPMs. Used to run at 48-5000 now its around 4600 WOT with about a 5 mph loss as well. <br /><br />I have replaced the fuel filters, put gas treament in and ran 93 octane through it. Helped slightly, but no significant difference. I checked the linkage for the throttle and it has not slipped. Checked the prop for line/fouling. Nothing. Plugs new last year. <br /><br />Motor response is great, sounds good, nothing at all unusual except the loss in torque/RPMs/speed. I am still able to use the boat, and can cruise at normal speeds after I let it work itself up to being on plane. This motor has been babied and there are no visual signs of wear. Any clue what could all of the sudden be causing this problem? BTW, same gas was in it through out, until the problem happened, then I put the treament in with 93 octane. It ran awesome on the same gas it ran crappy on. Thanks for the help.
