    Alpha 1 Gen 2 - leak & transom service questions

    Thanks for your responses. When running with hose connected to intake, please verify that I should start it first, then turn on water (to avoid forcing water through the block) and turn off water before killing engine. Thanks

    Alpha 1 Gen 2 - leak & transom service questions

    best I could tell, the drip was accumulating at the base of the y-pipe. I searched to see if it was above that point and running down but could not see or find any other source. i already pulled the drive for impeller service and figured I’d inspect the bellows while I was there, and thats when...

    Alpha 1 Gen 2 - leak & transom service questions

    1999 Stingray 4.3 - owned since 2013. 216 hours on the meter. Original bellows (25years); shift cable & cable boot replaced in 2016; impeller serviced regularly; trim sensors have been disengaged and “bypassed” since 2005. Primarily used in salt-water, but well rinsed with Saltaway and dry...

    Stalling, sudden low idle.

    Will do. Curious, though. Is there signal from the tach back to the engine, or is there an electrical change that the engine responds to?

    Stalling, sudden low idle.

    I didn't remove the throttle cable when adjusting the idle. THAT explains a lot, and jives with my expectation. also, having it at idle, while in gear, is exactly what I had, and now have again. At higher rpm idle without removing the cable created the "lurching" - dangerous, and nerve-wracking...

    Stalling, sudden low idle.

    Updates: 1) fuel pressure is still dead on at 6psi. 2) Plugs look clean: 3) No fuel leaking in carb. 4) fuel is clean 5) Ran her all weekend with no further issues. Before taking her off the water, I played with the carb idle adjustment. I found that at lower RPM (400 rpm, based on dash...

    Stalling, sudden low idle.

    Thanks! I replaced the stock carb with an: Edelbrock 1409 Performer Series Marine 600 CFM Square Bore 4-Barrel Air Valve Secondary Electric Choke New Carburetor I replaced the fuel pump at that time, too, but struggled to find a compatible pressure. Pumps were over 10psi and the carbs req max...

    Stalling, sudden low idle.

    some more detail: ran last night relatively well with the minor adjustment that I made to carb screw. i had a low throttle issue, but only high issue after I made an adjustment. I turned it back down 1/2 way after that And no more high issue. the big difference i noticed, and I hope this is...

    Stalling, sudden low idle.

    Thanks for replying. 2004 4.3 mercruiser repower. I replaced the fuel filter and carb 2 years ago. Looks clean. Only issue I had with fuel was that mfg listed 12-15psi on fuel pump but carb was limited to 7psi. i could not find a lower psi pump, so I added a pressure regulator. Worked...

    Stalling, sudden low idle.

    I turned that screw back down a little. It’s not lurching anymore but still idling at 420rpm. Is that the right idle adjustment for a 4bbl Weber carb? Is it possible that my tach is just not reading accurately?

    Stalling, sudden low idle.

    I turned the screw until the tach raised. I thought “that was easy”. (Not sure I did the right thing). I don’t have a separate reach gauge to hook up. Now it’s idling at 850, bit when I put it in gear, it wants to lurch. Makes me think that’s not the idle, but something else. Thanks.

    Stalling, sudden low idle.

    Mercruiser 4.3 warmed up fine. Dropped it in the bay and she kept stalling in nuetral. Just seemed “cold” at first so I let it warm a little longer. Finally behaved as expected. Didn’t even get out of the harbor and I noticed my throttle was high, but she was barely moving. Then she stalled...

    Can someone point me to the procedure for the balancer and housing removal? thanks

    4.3 crankshaft/housing oil leak - next steps?

    in there any chance that I can repair this without removing the engine? I’d prefer not to, if possible.

    4.3 crankshaft/housing oil leak - next steps?

    Thanks Scott. I have isolated the drip from under the crankshaft a seen in the photo. no oil above, none below. That drip is coming from the block side, right in the center of the shaft. Looks like seals to me, but I've read that seals are unlikely source. I cannot get a better view in that...

    4.3 crankshaft/housing oil leak - next steps?

    greetings all. found oil in the bilge and isolated it to the crankshaft seal or housing. Does not appear to be an oil pan issue. I found no obvious corrosion around the housing (from what I can reach). Lost about 3 oz of oil after a 3-day weekend - running ~ 8-12 hours at various speeds...

    Engine hour meter clicks with ignition on, but engine not running

    I’ve got 3. Off, on, and start. I don’t leave it “on” when at anchor. I typically only have it “on“ when the engine is running. i was testing gauges with the ignition on, on the trailer, w/o the engine running, just to see if I got different results when ignition was “on” vs “off”. I...
