    1972 Merc 650E 3 CYL....fuel system Qs

    Wires can break internally unseen. I would be very surprised to find the Insulation uncracked, on that motor, as Mercury had bought enough wire with an insulation that didn't age well, to go to the Moon and back severqal times.

    Does EFI solve the hard start/cranking issue?

    The Wires on the Lark went into the Exhaust Housing about 1/2 way down. If they were getting burnt, it was likely from not enough Water in the Exhaust. The Hydro-Electric case on the Triumph, would default to Forward any time there was no Power, going to the Shift Solenoids, and/or any time the...

    1989 Mercury Classic Fifty 45hp Timing Screws Identification

    On these engines, there is NO Idle Timing Spec, as the Timing is retarded to what ever it needs to be to get the correct Idle Speed. The Carbs are fully closed at Idle, and in most cases barley open until all the WOT Timing has happened. Pickup Timing refers to where the Timing has to be when...

    1972 Merc 650E 3 CYL....fuel system Qs

    The number of Filters could be part of the Problem. Try removing the filters from the equation, Fuel Lines can break down internally act as Check Valves and Restrictionn. The bulb gets firm, when the Bowls fill up and the inlet valve(s) close. Sometimes, the valves can be forced off the Seats by...

    Mercruiser 5.7 wanting to stall at idle after driving around

    It shouldn't be dripping like that. Is the Timing set correctly? If the timing is retarded, the throttle will have to be opened more to get the idle speed up, and the increased Airflow can result in the Nozzles feeding fuel. The little Clip you tossed, is there to lift the Needle Valve off the...

    Does EFI solve the hard start/cranking issue?

    The Lark was Electric, the Triumph was a Hydro-Electric. I always thought both were well Engineered. Clean Oil, of the right type, and keeping water out of the Case, and they would last a long time.

    De-Winterizing my 1974 Evinrude Lark 50 50472M Engine and no Crank

    Can the engine be rotated by Hand? When an engine is submerged, it takes a lot longer running than 15 minutes to insure it is dried out, I always ran them over an hour , hour and a half, under load so they would get warm. You say you drained the Starter. Did you take it apart, clean, and relube...

    It is a matter of Preference, as there is no right or wrong. They do provide an easy way to fine tune how the engine responds to Throttle and were developed so people weren't taking drills to their Props

    Turning Vintage and going Chrome

    Like any old car, we have Creaks and Squeaks, some Body Panels are dented and creased. We take a lot longer to warm up and are slower to get moving and Rev Up, though on Occasion, seeing a Young Fresh Battery does create a Surge of Energy, however the old Battery is still lurking there, draining...

    All the Plugs have curvature, even the ones with vents. The one at the top is rotated enough to make a determination difficult, and is only about 69 pixels across in that image

    Small crack in fiberglass hull with stains

    A bit of polyester Resin, with a Filler to thicken it applied, then a bit of Gelcoat to cover it. Myself, I would just use 2 part Epoxy Putty to fill the wound, and leave it unfinished. When selling it the Repair is visible, and it can't be mistaken for "They had to repair a very large Area..."
