    The prop I need doesn't exist

    I have a 1993 Evinrude 48spl mounted on a 1985 Whaler 15 foot Sport. The current 17" pitch aluminum prop only revs to 5000 rpm, putting it squarely in the middle of the 4500-5500 operating range. I have a 15" pitch SS prop that easily over revs to 6100 rpm, kicking in the rev limiter. Not good...

    Tach is fixed, but why?

    Last year I launched a 1985 Whaler 15 foot Sport, with a 1993 Evinrude 48spl. No problems at all. This year it tested great in a barrel so I launch again. Works fine so I go fishing the next day and the tach is suddenly idling at 3000 rpm and going off the scale at WOT, very odd since the prop...

    Electronic bilge pump switch

    Anyone use these? I want a bilge pump on my 15' Whaler and there is precious little room in the sump for a pump let alone a float switch. Thus I figured one of the new small electronic switches would fit easily and be reliable. I can't find the size dimensions of the Johnson Ultima anywhere, and...

    Wacky replacement tach

    On a friend's boat the Teleflex tach quit, so he bought a new one and it wouldn't work either. I tested the old tach and it still worked fine. So I checked the wiring and found a probable tach signal wire break in the main engine harness as it exits the motor (1982 Evinrude 35 hp). Twisting and...

    SS vs. AL = different performance?

    I had my setup dialed in perfectly. 1985 Evinrude 30 hp with an '80 35 hp carb with a #58D jet on an 18' Lund aluminum skiff with an old 10 X 13 SS OMC prop. It tached out at exactly 5800 rpm with a good holeshot with me alone or with my 10 year old Grandson aboard. With another adult aboard it...

    2003 Johnson 3.5 two-stroke won't shift

    The motor starts and works fine. We can't get the shift lever to move. When we pull the starter rope, it seems like it's stuck in neutral, but turning the prop it acts like it's in gear!?!:confused:. Lacking any type of manual, can anyone describe how the shifter works? I see in BRP parts...

    Home made lower unit pressure tester

    There are a lot of water-in-the-oil threads so I just thought I would throw this out there. Any water means a seal is leaking, and it can be as easy as an oil fill plug seal or as hard as a prop shaft seal. The key is finding which ones are leaking. When I rebuild a lower unit, I test it for...

    1986 Evenrude 70HP lower unit is getting a small amount of water in it with each use

    Re: 1986 Evenrude 70HP lower unit is getting a small amount of water in it with each Any water is bad. Do as Big Bubba said, change those seals first. Then pressure test the lower unit and double check for any other leak. A dealer can do it or do as I did and rig up a test fixture that screws...

    just rebuilt carb gas still streaming out of carb!!

    Re: just rebuilt carb gas still streaming out of carb!! I just went through a flooding carb. I took it all apart and found nothing. Now it runs great again. When you rebuilt it did you use all new parts? Float too?

    Hot day = high speed lean out?

    This is the '85 Evinrude 30hp again. I put a new prop on today and when I tested it I got a high speed lean out, no detonation, but rpm's wandering about 500 up and down, anything above 4000 rpm. Takeoff was good and jumped right up on plane, no hesitation. I squeezed the fuel line primer bulb...

    20hp Johnson outboard stopped squirting water (impeller or water pump?)

    Re: 20hp Johnson outboard stopped squirting water (impeller or water pump?) What you are showing is the exhaust bypass, which allows an exit for the exhaust and cooling water when the motor is idling and can't overcome the water pressure at the thru-hub exhaust exit. That is a good thing, but...

    30 hp emergency flooding cure?

    My '85 Evinrude 30 hp suddenly quit running the other day. Plugs were wet so I swapped in new ones. Still no start. Then I noticed gas was dribbling out the carb throat as it cranked, like as if for every pulse of the fuel pump. Flooding. Luckily my friend was nearby and he towed me in. I...

    OMC side mount controls-ambidexterous?

    I have a set of right-handed 1993 OMC side mount controls that I had mounted on the starboard side of a skiff. I want to use them in a Whaler with center console but on the starboard side of the console as well, but that puts the handle and kill switch up against the console. Can the controls be...

    30 hp rough midrange

    Hi, I've been reading all the topics on sync and link, jetting, carb cleaning, timing, etc, and still have a problem. Over the winter I tore down a 1980 Johnson 35 hp w/remote and an Evinrude 1985 30 hp tiller and built one motor. I used the 30 hp powerhead and compression is 150 psi on both...

    1980 35 hp shift rod adjustment

    I have been searching the many topics related to "jumping out of gear" and I find that either the gear/clutch dog may be worn or the shifter can be out of adjustment. I had to remove the lower unit for another problem and now mine jumps out every now and then at WOT. One poster mentioned that...
