Ranger Rob, every one of your posts we learn something new about this motor. First post you said it had around 40 hours, then next post your confident it has no more than 30 hours, then we find out it has been sitting for 4 years and all it had was stabil in it, and I'm assuming you did not put any fresh gas in it before you ran it, and now it won't do anything but idle
That boat will scream, when it's had all the injectors removed and cleaned, new fuel filters put in, spark plugs, fuel lines, and the gas emptied with fresh fuel added. Nothing wrong with the boat, but if you keep running it, you will have major problems with the motor. If you plan to purchase this boat, you will have to do all the above in order to get it running properly. First thing first, you need to take it to a service shop and have it checked out, it may actually have some big issues but we hope not. But, I definitely would not buy a boat without getting the motor checked first, even if it ran great for the test ride. Good Luck!
