    Honda BF15 15HP outboard dies at full throttle

    Old gray fuel hoses used to have an internal second sleeve which deteriorated over time in small pieces and partially clogged the hose when more fuel intake was in demand, check if it's a single or double sleeved fuel hose. Been there and that sucker nearly drove me insane till the culprit was...

    Applied a thin coat of Permatex Aviation on both exhaust covers and on front block and cylinder head mating surfaces edges. The PM had to be previously thinned with thinner as this stuff is very thick if applied directly, a 5 minutes air dry was needed to become tacky. Now both exhaust covers...

    Fouled Crankcase.-

    What's no wash on pistons domes/heads ? low temp. That motor had all their water passages cleaned to mint factory conditions along installing a new OEM thermostat. The motor keeps fouling the plugs not inmediately though, as the motor doesn't count with an installed hour meter can't possibly...

    Fouled Crankcase.-

    Year of fabrication doesn't say much, clocked run hours is all. That's why it's a must count with an installed hour/tach meter. If using good quality 2 stroke oils and fuel 50:1 mixed, spark plugs well gapped and in excellent shape, motor cooling properly and constantly run at speed won't find...

    Fouled Crankcase.-

    Because a 2 stroke motor will carbon up their combustion chamber and exhaust areas a zillion times more compared to an automobile, it's the nature of such filthy beast. Will add that those walls are porous ones and with hundreds of repetitive ON-OFF cycles will start to collect carbon...

    Fouled Crankcase.-

    This is a 2 stroke motor, old automobile decarboning trick doesn't apply here. the motor was manually decarboned before, a new head gasket with a light coat of Permatex Aviation sealer was applied and soon after evenly torqued to 30 NM in 3-10 NM consecutive torque steps. Oil/Gas Ratio 50: 1...

    Fouled Crankcase.-

    Both pistons and cylinder head were cleaned to near mint condition, the cylinder head gasket was found shot, overheated at one extreme, surely accounts for such uneven carbon up ? Will need to install a new one in... On these motors there will always be one piston carboning up way more than...

    Permatex Aviation Gasket Former.-

    The block's and cylinder head edges are not mint so will brush a light coat of Permatex Aviation to both mating surfaces and install the 2 sided pre glued coated gasket in between as there's no silicon impregnated whatsoever. For exhaust cover gaskets need to brush sealer at both sides, PA has...

    NS18E2 factory timing info

    Welcome to IBoats, With regard to the time advance/carb synch : stand at motor's front, throttle the grip to max and hold it there, check if the timing mark stops at 25º that's fifth line seen from left right at middle of both mating surfaces's line, the carb's butterfly must remain fully...

    Who has installed Helicoils ?

    Have seen many easy peachy YouTube Helicoil videos installs and none stated that need to install a shorter one due to its natural stretching capability once coiled than what the already threaded orifice depth calls for specially in blind non deep orifice installs. Luckily didn't went that way...

    Permatex Aviation Gasket Former.-

    Plan adding a light coat of such product at each side of the crankcase and cylinder head mating surfaces to paste up the edge's contour porosities the motor has developed over the years running in salt water. . The manufacturer recommends once a thin coat is applied at each surface let it air...

    Fouled Crankcase.-

    It was not listed in the 2013 chart, now is in the 2020, is the list upgraded yearly ? Vistony must be buying large quantities from a general US suplier, I don't think they've invested money in breaking down an engine to achieve their brand certification. Assume that any standard 2 stroke...

    The issue is going on again on that desktop PC with an obsolete Windows XP install, seems the antivirus NOD 32 whose license hasn't been renewed upon expiration is punishing me for it LOL. No issues with other computers running Windows 7 Ultimate... Happy Boating

    Fouled Crankcase.-

    Yep 2 strokes motors are not ideal to be used for long heavy work operations or constant daily tender use at very low rpm, worse if lubed or even excessively lubed way over 50:1 with a crapyy 2 stroke TC-W3 oil. Decarbon products such as CRC, Yam Ringfree, Quicksilver and others are gone, seems...

    Fouled Crankcase.-

    This guy is the culprit : Have checked it up in the TC-W3 Registered Two-stroke-cycle Marine Oils and there's nothing about that oil branded as Vistony or Aquaoil although bottle states low ash NNMA TC-W3 rated. Have used moon back Tohatsu, Chevron. Akron, Yamalube and now Amalie Pro, all...

    This local bottled crap TC-W3 Oil is not mentioned in the 2 stroke cycle Registered Marine Oils and that says much about its cheap quality. Now a days can write whatever you like on the bottle... Happy Boating

    Who has installed Helicoils ?

    Hey FS, if something I have way more than enough it's called Creativity so won't teach me a thing... Finally ended installing a headless M8 x 1.25 Time Sert threaded in a non deep blind bolt orifice, now sits flat even in the crankcase's side wall. The issue is that no one tells you that...
