    Another prop question - boat is slow...I think.

    Alright I have an Quantum 1804 with a Force 150. I currently have a 13 x 19 prop on it, that size came with the boat. My rig goes about 35 or so and from what I'm seeing elsewhere, boats similar in setup should be hitting about 50. When I hit wide open throttle the engine goes to around 6K...

    Force 150 another oil leak question

    Thanks to everyone here again, had the boat out and after rebuilding the fuel pumps and carbs it ran like a champ today. In fact I even saw a guy out there with a new merc, I don't think he could believe his eyes that my force was running as well as it was :) When I got back though I noticed...

    Engine wont start :(

    I have an 1989 Force 150 (1508 Model) that I was using during a weekend on the river. Everything seemed fine until I was idling along and it just quit and wouldnt start again (this was after two days of running perfectly). Charged my battery, that didn't work. Tried a new battery from a...

    Removing Quantum 1804 Fish and Ski Tilt Tube

    I just bought a Quantum (Bayliner) 1804 with a Force 150 on the back. Knew when I bought it I was gonna have to fix the steering since it's extremely tight. However! I didnt look closely enough and it would seem that I'd have to remove the engine to get the steering cable out (because of the...
