recently aquired this toy --- previous owner said it ran great until a few weeks ago. I've read as many threads and posts as possible that pertain to this little quirk we're having.... seems from about 1/2 throttle to wot the rpms don't change!! so far I've disconnected the thermoswitch and ran it, checked all the water lines from the pump to the motor, replaced plugs, set carb to factory specs.... nothing has made a difference. I know this boat isn't a speed demon, but surely should do at least 30-35 mph!! We can barely get this thing to plane and then when you take a hard turn rpm's stay the same but the boat slows to almost a crawl then it takes forever to get back on plane !! Impeller and wear ring both look fair, but I'll be replacing both with good used or oem's... I'm headed out to tear into the exhaust ducts..... compession is good on both cylinders, but I'm starting to lean towards a head gasket, and possible a carb rebuild... I have no way of telling how fast the motor is spinning as I don't have a tach... any thoughts? any ideas? am I on the right track?
thanks for any and all info
