    Will 12' pontoon boat plane?

    I see one is rated to 15hp but not sure if that is enough to plane the boat. What are these rated for? A 14' would be the next choice. Thanks.

    '85 8hp power surges when throttling up

    This ercob at one point while excelerating, suddenly jumps up in speed. If it is backed off just below the surge, it doesn't run smoothly but it does at the higher speed. I ran it 16 miles on a 14' aluminum boat recently. It just gets up on plane, and surges after that. What would cause this...

    White powder corrosion on motor- a treatment?

    Got a 20hp engine block with a pull start that has a lot of corrosion on it. I took a dremel tool and used a drum sander to get a lot of it off and tried using Ospho to kill it which didn't work. Is there something that will. Thanks.

    E30ELCDM throttle/shift box adjustment

    I've tried adjusting the two cables to the point where it idles ok and the slow speed lever will stay down, in forward gear. Now the throttle won't move forward. It has a different lower unit than the original so I think the shift rod needs adjustment. What is the easy way to coordinate the...

    Can this carburetor nozzle cause prevent a motor from powering up?

    The motor is a J10REANA and won't power up. The brass tube inside the crack may or may not keep it from leaking , I just don't know. What problems can it cause? They cost $40-50 each. I posted this on Marineengine too.

    J10Rena engine

    Joe, 1992 Johnson 9.9 J10RENA idles great but only makes a half hearted attempt to get a 14’ aluminum fishing boat up on plane. It ran great when I first got it (used but low time) A mobile mechanic thought it was burning too rich since leaning the carb needle made it run better. He was...

    '86 Rude won't shut off and shocks

    This E30ELCDM's wiring harness was shot so I replaced it. The motor will start and run but won't shut off, and I got shocked up around the block and when I touched the shift box. The original wires color were hard to ID. I have a wiring diagram for 85 30hp and a '79 35hp. The '86 30 has 4 posts...

    How to connect '86 30hp shift rod?

    I remember the knob goes up and down to cover the shift rod end and the little plastic piece but can't see how it works. The knob screws up and and has threads inside but nothing to attach to. I will check the library manuals but doubt if they will help. Thanks.

    E2OCRC05 lower unit removal

    I disconnected the piece behind the window of the LUnit and it will drop down about 8-10" but won't come all the way out. Moving the shift lever still moves the unit up and down like it is still connected. What am I doing wrong? Its about an '85 Evinrude 20hp with pull start. Thanks.

    Old 15hp fleetwind knocks

    Evinrude superfast twin 15hp 15012-47097 This motor is new to me. I cleaned the carburetor and went from 30 sae to 24:1 two cycle oil. It is hard to start and it ran about 1 minute after putting the carb back on. It was knocking until the low speed needle was leaned out. After 10 seconds it...

    What would cause a Johnson 9.9 to run rich?

    I'm convinced the reason the motor won't get full power is because it is running to rich. The motor is a '92 J10rena. The carb had a kit put in and the plastic cover has been replaced with the upgrade. The float is adjusted as per manual. The only thing I can think of would be the needle/seat is...

    E8RCOB Evinrude 8 hp cam adjustment

    The motor is a 1985 Evinrude E8RCOB and the cam needs to be checked for the correct adjustment. There is a star screw on the left side and one on the white roller. How is it adjusted? I do know the throttle plate usually starts to move when the index is in line with the roller and should be...

    How do I check for voltage at key switch on M50D Tohastu? Schematic?

    3E3 5059 M50D about 1992 The engine won't turn over. The neutral switch in the control box works ok. I can jump the starter and the motor runs ok. A new key switch didn't help. Are the male red and female green wires at the control box where the 12volts come through? If I want to bypass the...
