    Rough running and carb cleaning mith

    I just discovered that my motor rough running was nothing more than an air bubble in the gas lines. I had one of my sons pump the bulb while giving the mootor gas and the rough running ended. Motor runs fine now. I think carb cleaning is recommended way too many times here in this forum...

    2000 115hp bogging down

    Got the motor started after the winter. Started fine, some oil burning which I assume is normal after the winter (did not winterize). Engine stalls when trying to shoot from the hole, like a cylinder is not firing. After about 15 seconds the motor idles fine, but cannot rev when engaged. Changed...

    New prop for boat

    I own a mako 171 that is paired with a '00 Johnson 115hp. It has a 13 1/4 x 17 pitch and it produces 5900 rpm at WOT. I use the boat for fishing and waterskiing. I have no problems coming out of the hole when waterskiing. Would a 19 pitch benefit the motor? Thanks Dave

    johnson '00 115 hp slow reverse

    I have the motor control mounted on a horizontal surface on the console of the boat. It seems there is not enough room for the throttle (in reverse) to rev up the engine so I'm concerned that one day I'm going to need a good reverse action and I'm not going to have it. Is there any way of...

    Very hard to start

    I own a '00 Johnson 115hp ocean runner (2 stroke). I have owned it for 3 years now. It is VERY hard to get started in the spring. I mean it takes about a good 10 minutes of stop and go cranking before it shows life, and then another 10 minutes to get it started. After it starts for the first 10...

    Approximate weight of lower unit?

    I am planning to change the impeller on my '00 Johnson 115 hp. I have a couple of herniated disks and want to know how much that lower unit weighs so I can plan an attack. Is it as easy as ordering the kit and unbolting the lower unit? Thanks to all. Dave K

    '00 Johnson 115hp 2-stroke

    Is it true that a pinion in the starter wears of or free rotates so that it the engine does not crank?? I was told that this is a fairly common problem and it is better to change it as part of yearly maintenance. Thanks

    Carburated or not?

    Is the '00 Johnson 115 Ocean Pro carburated or injection? I am planning to do a carb cleaning if carburated. Is it difficult to do? Of course, I'm hunting for a manual already. Thanks, Dave K

    Propeller/RPM question

    I just purchased a 17' cc with an '00 Johnson 115hp Oceanpro. I is fitted with a not so new 13-3/4" x 15 pitch prop and it revs 5600-5700 trimmed up with 2 adults/gear. Is this too much? I took the boat to a shop and he recommends a 13-3/4" x 17 pitch. I'm planning to use the boat for...
