    2005 MerCruiser 4.3L MPI won’t start hot

    Ok. I spent some money, did the cap, rotor, plugs, IAC, fuel/water filter and a new idle speed control motor. She runs much better. Idles fine and runs - BUT, after an hour of sitting, she has trouble starting up. I imagine this is the check valve assembly (single drain) part 864206A1 that needs...

    2005 MerCruiser 4.3L MPI won’t start hot

    I failed to mention it’s an MPI. I’ve fixed that now. Engine serial is OW318000. Unknown when it was last tuned. New to me. Water separator looks new.

    2005 MerCruiser 4.3L MPI won’t start hot

    Hey guys. I’ve read a lot of threads and want to decipher whether I have a vapour lock or perhaps a sensor that’s gone bad. I’m trying to avoid chasing this problem by just throwing parts and money at it ! Facts are 2005 Hurricane SD187 with 4.3L MPI engine. I just bought this Michigan boat with...

    Mercruiser Alpha 1 Gen II leaking above speedo hose

    Hey y’all Have a 2008 Sea Ray 185 with 4.3L carbureted tks - just got the boat. When I fire it up on the hose, water seems to be slashing out of the little hole on the drive, above the Speedo hose/fitting. Please see pics … question is - is water suppose to come out here or is my drive cracked...

    Is @Bondo still in 1000 islands ? Maybe he can suggest a machine shop or a place that has short or long blocks ?

    2004 Volvo Penta 3.0L engine knocking

    Hiya 2004 Glastron 17ft with a 3.0L original engine (red). Ran fine then the knocking started. Not sure if it threw a rod or 2 but there’s no compression on 1+2 and not really sure what else is going on. Shut her down and took it out of the water. I have 2 questions. #1 Might this be fixed...

    2009 Mercruiser 3.0L TKS stalling

    I also noticed it’s flooding. Gas coming right up that main throttle shoot … readjusted float and needle/seat…. that seemed to have fixed it. I’ll take it to the water and see ! Thx Dodge !

    2009 Mercruiser 3.0L TKS stalling

    He y’all. Have an 09 Bayliner with the 3.0L Mercruiser - it has the TKS carb. Fires up amd runs for a bit then stalls. I took the carb apart, stripped it (except for the little “T”, spring and ball and the accelerator pump looked fine), soaked it, replaced all the needed parts in my kit and put...

    90Hp trim gauge reads backwards !

    I’ve just realized that this, even though it has the same casing number (CS0331) that doesn’t mean all of the guts are the same ! This is a 13123 which is OMC. I require the 13122 which is Merc ! Duh … but good to know for others reading this !! Thx Chris for your help.

    90Hp trim gauge reads backwards !

    Would that not cook the trim gauge ?

    90Hp trim gauge reads backwards !

    No. Ground in the middle, purple on ignition and brown/white on sender. As for the supply to the gauge, it’s coming from the cluster of dash wires. At the battery, I don’t believe it’s a separate hook up, it’s just part of the wiring harness. At the motor, all wiring is correct as far as...

    90Hp trim gauge reads backwards !

    I have a 2002 Glastron SX170 with a same year Mercury 90hp (ELPTO) O/B. When I bought the boat, it didn’t have a trim sender and the gauge did not work. I bought a brand new trim sender kit (Quicksilver 821400A 2) and a (what I think) was a direct replacement Faria trim gauge (CS0331 stamped on...

    2005 Sea Ray Sundeck 240 350 MAG MPI - no power over 3500 RPM, random alarm beeps

    Back for another season of troubleshooting ! Still can't get my boat running properly. BACK STORY: upgraded block from a 5L to a 350 MAG (MPI). I solved all kinds of issues and now while closing in on everything, while I'm on the water, I can't get this boat to go past 3500 RPM or about 30...

    Oil pressure sensor 350 MAG Mercruiser Smart Craft

    I started a new thread because my other one had several topics and this is the last of my problems !! (I think) Previously, I'd been getting a reading of FULL (100PSI) on my gauge for oil pressure when I turn the key. When I fired up the engine and gave 2000 RPM in neutral on the hose, the PSI...

    HI... Back again... 2005 Sea Ray 240 Sundeck...Bravo 3. 350 MAG. I've replaced the entire trim pump assembly last year along with the triple switch at my throttle.
