OK. Engine was working fine. I'd get 4,500 - 5,000 rpm no problem whatsoever. Took the four carbs off to rebuild (found a lot of varnish and crud in them). Put the carbs back on (in their original order), and the motor starts and idles fine. However, it won't go above about 3,200 rpm...
I just bought a really nice 2001 Pro Line 23 Walkaround. The boat came with a 2002 Yamaha 200HP Saltwater Series II OX66 with about 500 hours on it. I have been running the boat/engine every weekend for the past two months without a single problem. My boating habits take me 20+ miles offshore...
