    20 HP 4 stroke Honda WOT problem

    I overheated the motor; engine died. I changed waterpump impeller and now cooling's ok, motor works at mid range fineq oil is clear but it won't work at full power: I think there could be an activated overheat protection which limits WOT operation which should be reset; if so, how can I do it...

    v-4 crossflow powerhead

    I was looking for overhaul kits when I came across forged pistons and cast pistons and wonder if there is a significant advantage of using forged pistons?

    1982 90 hp Johnson

    I apologise for the question but out of curiosity I would like to know is there an extra credit or some bonus for a reply "it's in the manual, don't waste our time"; or it's similar to a pointed finger at a guy asking for a free ride? This reply always made me feel guilty for not being able to...

    Stator test

    Can any one tell me the voltage readings on stator - ignition power supply, voltage of timer base trigger, and voltage of power pack to ignition coils?

    Blown power packs

    Can cranking with disconnected spark plugs damage power packs and can blown power packs by inductivity influence readings on tacho? Motor charging - 13.75 V at low RPM - rectifier and regulator and stator o.k. Tacho worked fine on 2 and 3 cylinder engines - switched to 4 shows double r.p.m...

    Ignition on two strokes

    Do spark plugs light twice in a stroke of each piston? There are 2 magnets on flywheel for the timing base at 180 degrees and two or four sensors at 90 degrees in a four cyl engine. This shows one magnet passes sensor twice per 1 rpm - 1 stroke and spark plug fires twice or there is a counter...

    1982 90 hp v-4 voltage regulator

    I was wondering how the Vregulator works; it is connected to stator (yellow cableq minus and I couldn't trace the purple cable - most ptobably to ignition key, could regulator cause damage to stator, and how can I check it without engine runung?

    Blown stator on 1982 90hp v-4

    Can a blown stator cause the following: a. no charging b. double reading on tachometer on board and a tach on the spark plug leads(1500 rpm instead of 750) c. ignition timing trouble. I face these three problems and found only this fault. I wonder what could lead to stator damage, could it be a...

    V-4 90 hp 1982 serious ignition trouble

    I recently purchased a motor, checked up all mechanics and tested it on the boat. It knocks slightly when idling: knocking increases under load, it didn't have power. There are no adjustment screws on the carbs so I tried timing. I couldn't reduce RPM lower than 1300, when throttling knocking...
