    1995 Johnson J6REOD WOT issue

    Ran this 2-stroke for 27 seasons on a 14 ft Alumacraft Model A. Having issue this summer where at WOT it doesn't reach its normal range of 4500 to 5500 RPM, whereas it had no issues before. With my 8.5x9 prop only hits 4280 RPM, and with my 8x7 prop only 4700 RPM. (with just me and normal gear...

    Outboard temperature gage goes up with any accessory use

    Years ago I mounted a cylinder head temperature sender and guage for my 90hp. Has worked fine. It's powered from the ignition switch. This season I noticed it would go up with any accessory use, and none of these accessories are powered via the ignition. I thought perhaps the sender wire was...

    Gearcase pressure test 1986 Evinrude 90HP

    I'm the original owner of this outboard. I noticed some blue green oil on skeg and snow below it this last winter, so figured it was either unspent fuel (my 2-stroke oil is tinted blue), or gearcase fluid (mine is tinted green). Very hard to tell difference, but if it was really gearcase fluid...

    Why do some metal deck fills have ground wire at end of barb. I always used one of the mounting bolts for ground to tank.

    1995 Johnson 6 HP model J6REOD carb adjustments

    First time doing this, so I’m hoping to get clarification on two of the steps. I've attached image of the OMC manual page regarding carb adjustments. Hope you can read it. Step 1 (figure 6) Turn the cranking screw in until the spring is fully but lightly compressed. Fully but lightly - does...

    Suz DT115 cyl head - good spot for temp sensor

    I want to add a temp gauge to my 1999 DT115 and considered splicing into the wires of the factory temp sensor (on side). But since this goes to the control unit I don't want to possible change its properties by adding more resistance. I can add a generic sensor on bracket, but I'm curious what...

    1986 Evinrude 90HP crossflow no power

    I've owned this motor since new and was out Sat and noticed the tach was going crazy and it was also not charging (volts remained just over 12 at all speeds). Figured it was a bad rectifier, which I replaced twice over last 31 years. As we were going at about 15 MPH, all of a sudden it felt like...

    Cylinder head and exhaust cover - steps to lesson chance of busting bolts

    I have an 1986 Evinrude 90HP crossflow that I just changed the thermostats and water pump on, but she still overheats. I'm the original owner - only used in fresh water. I know I should pull the exh. cover and cyl. heads to see what’s up, clean passageways and change the water deflectors...

    water pump gasket - dry or use sealer

    I have a 1999 Suzuki DT115. The OEM manual does not specify using any gasket sealing compound on the water pump gasket. My Evinrude 90hp OEM manual specifies it. Would it help or hurt? I usually use a very light coat of aviation gasket sealer on these gaskets, as well as on bolt threads...

    gearcase to midsection bolt torque suzuki dt115

    I have a 1999 DT115 that uses 10mm bolts for the gearcase to drive shaft housing. The OEM manual states to torque them to 36 to 43.5 ft-lbs. I think its a miss print, because the beginning general section of the manual states to torque them to 24.5 to 29.5 ft-lbs. Does anyone know? If not...

    pickup point timing & throttle cable adjustment

    I have a couple of questions regarding pickup point timing and adjusting a new throttle control cable on crossflows. I have a 1986 Evinrude 90hp. After setting the cam follower pickup adjustment (using a shaft amplifier) to the pickup point (follower aligned with cam mark just as the carbs...

    VRO (3 wire vs 4 wire)

    Does anyone know what the real difference between the latest VRO (or OMS) pumps are? I see 5007420 (4 wire) and 5007423 (3 wire) being sold, and someone on Ebay motors is selling what they say is a combination of both kits. Does the 3 wire kit 5007423 upgrade you to 4 wire? I understand...

    Does anyone know of an inexpensive timing light that would work well with 2-strokes. Perhaps something I can purchase online for less than $50?

    VRO or OMS testing

    1986 Evinrude 90 HP I've been trying to identify a rough idle and unspent fuel/oil problem. I did all the standard tests and got up to testing the VRO. Ran clear hose on output side of VRO and pressure tested. At 800 RPMs the pressure would gradually drop from 7 to 3.5 PSI within 15 to 18...

    timer pointer, piston stop, excessive play?

    1986 Evinrude 90HP v4 crossflow OEM manual says to set pointer, rotate flywheel cw about 1-1/2 in. past TDC mark, insert piston stop in #1, hold flywheel so cylinder is against stop, and mark spot. My question is, how much pressure should I use to hold flywheel against stop before marking...

    High speed orifice sizing

    I rebuilt carb of a 1995 Johnson 6HP (J6REOD) and noticed the high speed orifice was size 50, but current parts schematics show 38. I bought the engine when 2 years old and doubt the carb was previously rebuilt. Do specifications change, or could they have simply decided this engine ran better...

    1999 Suzuki DT115STC charging specs

    Does anyone know how many amps its charging system is rated for, and if its voltage regulated? I'm considering using a AGM battery but I've read they require regulated charging at or below 14.2V less you will shorten their lifespan.

    Sinc & link - 1986 Evinrude 90hp V4 crossflow

    After replacing the powerhead to adapter gasket and all fuel, oil and recirculation hoses, motor idled better than last year even w/o a link and sinc. But had a leak- removed top carb and fixed a spit end on one of the new recirculation hoses. Reinstalled carb but no longer idles nicely...

    Is there any appreciable difference between Sierra and BRP gaskets? I noticed the BRP are usually a little more expensive?

    powerhead to adapter gasket: sealer?

    I have a 86 Evinrude 90 that's probably leaking at this gasket. The OMC manual for this year says to apply gasket sealing compound to a new gasket. The Clymer manual I have (printed 1992) that covers this engine states not to use a sealer. :confused: I've read on this forum that the original...
