    Can I replace throttle cable without pulling flywheel?

    Second owner of a 1998 4HP (E4BRECRJ). Throttle cable must be replaced. Cannot find aftermarket cable and at 20" total length, $105 OEM kit strikes me as uneconomic. My workaround is to fabricate a cable. Plan to reuse the cable sleeve, terminal ends and cable retainer to ignition plate. Had...

    interchangeable needle valve assembly? (p/n 396521 vs. p/n 396522)

    Troubleshooting intermittent (and highly frustrating) hard start and non-start events on my E3RCU. Compression and spark ruled out as factors. As part of carburetor exam, I wondered if my needle valve assembly might be at issue. 396522 is the p/n --- which of course I don't have on hand at...

    Omc 6hp 1969-1976

    See a number of 6HPs in this age bracket in my local market and wish to know what to expect if I pursue one of them. Are there any substantive factory differences year-to-year within this 8-year span. Is any particular year better or worse component-wise? Was the kW power rating system the same...

    Ethanol-Resistant Fuel Line & Primer Bulbs revisited

    My remote tank fuel line (or primer bulb or both) have deteriorated. Bits of black particulates are passing through the fuel barb into the line leading to the fuel pumps of my small motors. (Tank interior is clear and clean.) On replacement options, my local Napa has been little help. They don't...

    1998 4HP / help appreciated before I break it in process of reconditioning

    Several troubles with model E4BRECJ (new-to-me) on what should be quick & easy exercises: FRONT LOWER COWL REMOVAL: Neither the OMC factory service manual nor Seloc manual addresses removal of combination choke/fuel shutoff knob. The knob must come off before cowing may be removed. Reluctant to...

    Sporadic inability to start and sometimes restart engine

    Hoping someone can shed light on what has become a recurring problem: unpredictable inability to start cold motor AND sometimes the inability to restart the motor after a break of 15 minutes after use. This is a 2.5HP (E3RC). Problem has become more frequent and more serious coincident with a...

    Source to identify hotter spark plugs by model?

    In my OMC small motors, I would like to try hotter plugs versus those specified by BRP on its site. Anyone know of a matrix that might show alternate plugs according to OMC model & year? Any reasons against trying hotter plugs?

    disconnection of throttle cable from timing plate

    Attempting to disconnect throttle cable from timing plate. 1998 4HP. Somewhere in these pages someone must have beat me to this question. Does cable end snap out of vertical black plastic mount or must that mount be removed from the timing plate? Trying to free motor end of throttle cable in an...

    4hp throttle cable adjustment (VicS-Racerone-F_R-oldboat1-JoeReeves-others?)

    1998 Evinrude 4HP appears to have seized throttle cable (tiller twist grip design). Am attempting to remove tiller and lube mouth of cable with a homemade pressurized device. Have been through Seloc manual 3 times. Do not see detail that covers this model's tiller arm removal, throttle cable...

    Manual adjustment of throttle cable for test start of 1998 Evinrude 4HP?

    Model: E4BRECJ (1998 4HP). This is a F/N motor. Acquired from original owner who used it for 6 years and then forgot about it for 15 years. Trying to perform assessment, but am unfamiliar with tiller twist throttle type. Twist grip throttle has very little play in it. Also, decal is missing...

    Too much slop in starter on 1969 4HP Lightwin

    Pull cord condition, recoil function, idler (start) gear condition all seem good. But arm idler gear (part #43) -- the outer cup housing -- wobbles more than I would expect. The "sandwich" of the assembly is not tight enough for pieces to meet for starting, so I must apply pressure on the outer...

    Cooling Trouble / Diagnostic for top water tube grommet failure?

    F_R: I'm touching motor on underside of mount where midsection bolts to powerhead. Picture shows the area from underside perspective....where I perform my touch test. (On the water it's impractical for me to remove cowling and touch the block directly.) When advanced past 1/3 throttle this metal...

    Cooling Trouble / Diagnostic for top water tube grommet failure?

    Motor: E3RC (1987 2.5HP). Symptoms - motor is overheating per "touch test" when pushed greater than 1/3 throttle. Cools very quickly once brought to slow speed. When on the water, sometimes I hear a "clinking" sound in midsection, leading me to question whether water tube is vibrating enough to...

    1975 6HPs (Models 6504/6505) -- how does the '75 vintage compare?

    Anyone have a view on the comparative reliability, parts cost and repair ease of the 1975 6HP OMC model year vs the 6HPs before and after? Any noteworthy differences between the 6504 and 6505 variants? Assuming cylinders are relatively balanced, what compression results do I want to see? Thanks.

    Sm. motor - no thermostat - possibly overheating - isolation of fault? (E3RCUA)

    Motor: 1987 Evinrude 2.5HP (E3RCUA). Model design lacks thermostat. Tell-tale in form of spray generated through 8 small holes on midsection (4&4). History: Motor abused by previous owner. Plastic wire insulation showed signs of heat stress (melt) when I acquired motor. Since my rehab with new...

    1969 4HP (model 4906B) - equivalent part impeller housing

    Preparing to service 1969 4HP (4906B) with unknown previous history. Anticipating the worst. Seeking source of equivalent part for impeller housing or complete pump repair kit w/ housing. Perhaps under different part number. Prefer to match to Sierra if I can. Impeller housing: 0310344...

    Q on using Lubriplate as substitute for lower unit oil

    Question relates to small, direct drive outboard: 1987 2.5HP (model E3RC). Motor has at least 1 bad lower unit bearing. As a result, lower unit seals fail and water displaces lower unit oil. Lower unit bearings not easy to source at reasonable cost. Considering Lubriplate as a workaround. Some...

    Different fuel pumps for 4.5 hp with integral fuel tank vs. auxiliary tank?

    Am considering purchase of an older 4.5 HP (Evinrude 1980 E5RC). Model in question has an integral tank. I am wondering how difficult it may be to retrofit with a barb to connect to an auxiliary tank so I may avoid a refill procedure on the water. OMC shows part numbers for 2 different fuel...

    Advice from elder statesmen of small outboards re: light-weight 5HP?

    To frame my inquiry: Currently I use a 2.5HP (1987 Evinrude) as propulsion for a square-back fishing canoe. I’d like to acquire a 5HP 2-stroke outboard to shorten the running time to distant fishing spots. Fishing canoe design creates a weight limitation for the outboard. Believe I will reach...
