    Mercruiser 5.7 MCM carb low idling

    Hi guys, Always awesome here, the knowhow everyone shares. I have a minor question. My 2007 merc 5.7 TKS carb 2 barrel engine runs great but (tends to) stalls on me when hot and gets back to idle speed. It starts "stamping (galoping?)", oil pressure up and down, even low voltage 11V. RPMs 650...

    Mercruiser 5.7L MCM TKS Carb mechanical sound

    Hi all, The TKS carb is giving a mechanical clatter sound, not meant here is the normal suction sound from the TKS enrichment module at cold start proving extra fuel. The TKS module has been tested by me to be sure and is ok. During the last outage the engine was hot and stalled at low rpms...

    Startmotor 3.0L bendix difference?

It...

    3.0GS water intrusion with unclear failure mode

    Hi all, My Glastron 175SE got refitted with an 3.0L GM motor built up from several components of my former engine (GSMBYMCE) as I had severe water intrusion. Essentially we only recovered the electrical harness, had the carb rebuild and replaced all the casting and internals by basically new...

    Identifying 3.0GL (1994) power output

    I am considering to buy a Volvo Penta 3.0 GL MMDA newly built in 1994. I have a Clymer service manual 1994-2000 stating the GL has 120 HP power output. As I had a 3.0GS (GM Superior output : 135HP) I can image the GL has less (GL Limited output < 135HP). The thing is that ONLY the service manual...
