I have a '99 355 with Crusader 454's. It's been a little over a month since I took her out and both engines wouldn't go past 3200 RPM maintaining 18-19 mph WOT. She can usually go up to 29 mph WOT so figured the marine growth was causing the strain and hoped some of the growth would fall off and her speed would improve slightly... but never did. About 20 minutes into the trip the transmission oil overheat light came on the port engine thus the computer forced both engines to power down (but did not shut off). The light went out after the power down also. I put her in neutral then back in gear and putted all the way back to the marina at about 1200 RPM with no other warnings or issues. I didn't attempt to bring her up on plane again because I was just happy she was moving. Marine growth issue? Sensor issue? Any thoughts I can tell the mechanic to check into? Thanks everyone!
