    Please don't groan....I'm trying to rebuild my carbs and adjust my jet sizes using primarily my pile of spare parts, but I have a few questions: Background: I have been running a pair of 1 5/16 throat carbs (1982 generation) w/ #36 (throat jets), and #29 and #67 (bowl jets) for a couple years...

    V4 Crossflow - flywheel cut into stbd bank timer base wires

    Accidentally left my timer base wires in harms way after recent work on my engine and the bottom of the flywheel was rubbing on the wires which run over the top of the engine to the starboard power pack. Limped home on two cylinders, and ultimately the flywheel rubbed through all the...

    need assistance troubleshooting v4 crossflow combustion problem using spark plugs

    Have a 1986 V4 110HP crossflow not VRO (not new to me) . Currently the engine runs only on the port/left bank (cylinders 2 and 4) b/c there is no change in operation when I remove the boots from the plugs on the starboard/right bank. Verified strong spark and even (but low - 95psi) compression...

    Electrical question re: late 80's and early 90's crossflow v-4

    I feel stupid asking this question, but do these engines require BOTH the water cooled voltage regulator unit that mounts to the top of the engine AND the rectifier diode that mounts next to the electrical bus bar on the starboard side of the engine? For some reason I was under the impression...

    1989 Johnson 110 VRO electrical diagram

    Anyone have an electrical diagram/schematic for a late 80's/early 90's generation V-4cross-flow w/VRO? Finished putting mine together based on pre-disassembly photos, but when I bought the engine it was missing a few parts (i.e. stator) and was partially disassembled already so I want to verify...

Everything appeared to work properly at the house on the hose when I tested her after the job...strong water flow out the pisser and lower unit. Splashed the boat...

    Rectifier/Voltage/battery switch question

    had the boat out last night and the dash gauge read the normal 13+ volts when underway as long as the battery switch was on battery 1 or ALL. If I put it to 2 only, then the whole instrument panel lit up extra bright and the voltmeter pegged at like 18-20 volts. Any ideas? I have a new...

    crossflow exhaust manifold...bubbleback vs flatback?

    Rebuilding a 1989 johnson 110. Hoping to replace the factory bubbleback housing and rotted/warped filler block assembly with the flatback assembly I have from another V4 crossflow engine b/c it's in better shape and saves me $150 or more in new filler block parts. Anyone know if I need to...

    Wierd OMC tilt trim behavior

    Can't wrap my head around this one so was hoping someone else with a bit more familiarity might be able to shed some light. Recently replaced the motor and piston seals on the T&T for my old V-4 Crossflow. Did NOT do a complete overhaul b/c didn't think anything else was wrong with the system...

    center console transom fiberglass project

    Just picked up an 18' center console hull and realized after getting it home that someone notched out the transom even lower (approx 4 inches) than the original factory cutout...I imagine to accommodate a shortshaft engine. Unfortunately, the engine I have is a longshaft. Any suggestions as to...
