    1995 Yamaha 40 ELRT Has Chirping Noise at idle

    My 40 ELRT was running a little rough and would not idle. I rebuilt the carbs and got it to crank and run nicely but when it comes off of fast idle, the motor "studders" randomly and "chirps" loudly. The noise comes from just above the intermediate housing and a little puff of smoke comes out...

    Tohatsu 90HP lower unit linkage issue

    I purchased a 1990 Tohatsu 90A that has a frozen lower unit. I have tried to remove it but cannot get shift linkage loose.

    I have a 2001 150hp Saltwater motor with carbs. The Water pump impeller has been replaced but the tell tale hole does not pee water at idle and it only sputters at speed. I checked the thermostats and one was closed and the other was partially opened. I removed both t-stats and the tell tale...

    1999, Yamaha 90 Carb - Primer question

    I have a Yam 90 with the Primer carb rather than the choked model. The engin is hard to start but I checked the primer selnoid and have .4 ohms resistance, so it checks out. The blue wire is connected to a harness that appears to go up under the flywheel. I cannot get any power on this blue...
