    1990 V4 runs on two cylinders at low RPMs

    I rebuilt both carbs, put it back together, and tried to start it. Mostly won't run, but finally got it to stay running, but shut it off after 20s or so because it is leaking a lot of fuel. I had the air silencer cover off. There is a fair amount of fuel pouring out of the two brass tubes...

    1990 V4 runs on two cylinders at low RPMs

    Maybe I wasn't clear. The electric primer seems well made. It's the particular aftermarket replacement parts (I think not Sierra in this case) that have a bad reputation in the reviews I saw. But people mostly complained about the valve and the o ring leaking. The only part I need from the kit...

    1990 V4 runs on two cylinders at low RPMs

    The hose attached to the air silencer was not attached to the motor. I see what is probably the fitting that it attaches to at the bottom of the motor. The hose is split for 1/2 or more on the loose end. I wonder what caused it. I could trim the split part and try to reattach it, but I don't...

    1990 V4 runs on two cylinders at low RPMs

    Thanks for the pointers. I hope I didn't damage it. I thought maybe the cylinders were getting too much fuel. But yeah maybe it's too little. I got carb kits. I'll start with the lower one. I'll measure the compression again when I put it together. Don't know if any damage I might have done will...

    1990 V4 runs on two cylinders at low RPMs

    The motor is tilted all the way up. I lowered it into the water. A good amount of fuel trickled into the water from gaps in the bottom of the the engine housing. I had not started the motor. Start motor and idle at dock. I have to idle quite high or it dies. Did a drop cylinder test. Removing...

    1990 90HP E90TLESB rough at low RPMs

    I replaced plugs right after I got it. Checking compression a couple of weeks later, I noticed one plug looked brand new. Swapped two coils and discovered it was a bad coil. The motor runs worse now at low RPMs than it did on three cylinders! I just started searching online. Other people have...

    1990 90HP E90TLESB rough at low RPMs

    I've been mixing ethanol-free gas and oil at 50:1 since I acquired the boat. The previous owner had disabled the VRO. I haven't looked at where the fuel pump is mounted.

    1990 90HP E90TLESB rough at low RPMs

    First post is kinda long. Short version: Motor suddenly started running rough at low RPMs. Dies immediately when idling. I have to lower fast idle lever quickly and slam it into gear. I need 1200-1500 to keep motor running. Before problem, 750-850. Increasing throttle through 2500-3000 (maybe...

    1990 90HP E90TLESB rough at low RPMs

    It was running ok when I left town for week. My wife ran it at low speed for 3 minutes (across a lake). It would not start. I started it when I returned, but it runs very rough at low RPMs. Won't idle, I have to drop the fast idle and slam it into gear. I got the boat a couple of months ago...

    Bought boat with wrong title

    Thanks. I've been working with law enforcement friends and the seller. It's going slowly. The seller is apparently willing to get a replacement title (says he no longer has it.) But that is difficult. At this point, I think it was an honest mistake.

    Bought boat with wrong title

    I found the HIN on the boat. It's completely different. I plan to contact him, just wanted to get my ducks in a row first. The seller seemed pretty shrewd and careful, said the boat has been in his family since new. My best guess is that he gave me the wrong title on purpose for some reason...

    Bought boat with wrong title

    I bought a used pontoon boat. The title and the boat don't match. The length is different and the manufacturer is different. The first three characters of the HIN are for one manufacturer and they expected characters for the actual boat are different. Still looking for the HIN on the hull. Have...
