Bought this boat about 8 months ago, finally took it out 2 weeks ago to break it in (weather it needs it or not is unclear in man.) Runs for 15 min ok then dies, almost impossible to get it going after this. Did the exact same thing 4 times on 2 separate outings. After the last time I had the boat back in the truck and decided to check the gas, upon opening the gas tank you could hear a Pssss--- it had a vacuum in the tank. The one way valve air valve on the tank lid was not working. Nipped off a bit of valve just so you could see crack----Problem solved. Next issue, approx. 21/2 tanks on it and you can not get past 1/3 throttle or it just boggs down and will die, if you let off the gas and keep it at 1/3 (approx. 15mph) it will go forever. When you first take off it goes like a bullet for the first 50 feet then bogs down. Slow idle at 1 turn and the fast anywere from 7/8 to 1 3/4 does not make much diff. Checked fuel lines fuel filter. Next issue Muffler noticed that almost no water was coming out of the muffler cooling port on side of boat (motor port has good flow) Brought home and hooked to water pump and ran engine,90% of water comes out of tail pipe. Is this designed this way or do I have a lemon? Also auto sinkers (bailers) let 10x more water in than out. Any insight into these problems would be appreciated. I have 2 other Zenoah motors in my 1/5 trucks and they run flawless. This boat is possessed!
