Hello everyone, new to this site and more importantly new to boats and boating. I just bought my first 14' aluminum fishing boat with a 1965 Evinrude 9.5 Sportwin (?) motor and trailer package. Just wanted something smaller and cheaper to get my two young kinds out fishing with their old man. I bought the entire package for $1250.00 here in Ontario. I saw the motor run when I bought the boat in a pale.
Heres my problem: So I brought the boat home and having a few freinds with boats have done the following. First I checked and cleaned the spark plugs, lots of spark. Then I checked compression, had a little over 65 psi each cyclinder. Changed the bottom end oil and installed a new impeller. Cleaned the filter inside the gas tank.
On the first ride close to home in a very small lake I drove it around for about an hour at all speeds without any problems.
The second time, the motor starts right up and operates normal. At low speed all is well, but once in awhile it start to stumble. If you open the throttle, it tries to die. When this was first happening I noticed the vent was closed on the gas tank and thought that would be it, nope. Still did it the next time out. So I tried squeezing the "primer ball" when this was happening and noticed it had next to no pressure on the ball and when squeezing it I was able to open the throttle.
The next time I took the boat out, the primer ball trick didnt work so well and the stumbling seemed worse. I thought ok maybe the fuel line is bad, but it looks new. the weird part is that when ever it stumbles and sometimes dies right out, it will always start right back up, everytime. I have learned to shut the throttle when it acts up (which is alot, nearly all the time I'm over 1/4 throttle) and ease it back open.
Needless to say, its a real pain in the butt. I dont know if the carb needs to be cleaned or what the heck is going on. I am very mechanicly inclined for atvs/motorcycles but this is my first boat, and I need advise.
Please advise, sorry for the long post.
Thanks HEMIJBI.
