I have a 1988 Prov150. Always runs peeeeeerrrfect.
Last week I went to the lake and like a dummy, put the drain plug in the wrong hole. The rear of the boat filled to the top covering all batteries, oil reservoir and gas tank.
I decided to run the boat after draining everything to see what would happen. The boat idles smooth and I can rev it up as high as I wish while in neutral. Problem is when I excelerate, it will not go above 2000 RPM's and 8 mph.
I have replaced the spark plugs, oil on side of engine and main reservoir and drained the gas tank and put in new gas. Still no luck.
I have squeezed the primer bulb and hit the choke switch while driving and no change. Compression is good. Overheat alarm works fine also.
The challenge I have is everything I have read on other forums points to something limiting the RPM's like the overheat alarm does, yet my mechanic, without looking at it says I need to rebuild the carbs and charge me 5-8 hours to "restore" it.
I am just throwing this out there to see our great forum can help.
Also, everything I have read.....no one ever says what fixed their problem. I will be sure to do so as to help the next person.
Thanks.
