    Mercury 60HP 2 Stroke 75HP Stator swap?

    Can you take a stator off a Merc 75HP 2 stroke (which has a different type of switchbox design) and fit it straight onto a 60HP with its original switchbox? I guess the question is, should stators and their corresponding design switch boxes be used together, rather than mixing types? This is...

    Mercruiser 4.3 MPI - operating in warmer seas

    Hey all! I have a healthy 2005 4.3 MPI, fully serviced etc that runs great. We normally boat on water that has a temperature of around 60F and have zero issues, boat sits at 160 all day long. Question is - we’re taking the boat on vacation and the area we’re visiting has water temp of 77F...

    Mercruiser 4.3MPI 2005 SmartCraft Connector location?

    I am trying to connect a VesselView mobile module to my 2005 4.3MPI. However, I can’t locate the smart craft plug anywhere on the engine. I have looked thoroughly down the back and sides. I can’t seem to locate it. The boat has basic analog Faria gauges, so therefore doesn’t have smart craft at...

    Alpha 1 Gen 2 Gimble Bearing Grease Nipple

    I have a 2005 Alpha 1 Gen 2 outdrive - don’t know the history of the gimble bearing (sealed or greaseable type) - does this cap give away which it might be? - read somewhere this cap is sometimes installed to stop you greasing it? Am I safe to squirt a few shots of grease in here to see if...

    Noisy water pump? 4.3MPI

    Hi, I have a 2005 4.3 MPI MerCruiser that sounds a little strange. Does this sound like it is coming from the water circulation pump? Hard to tell when listening to it. I’ve replaced the alternator and it still sounds the same (that wasn’t charging hence the swap out) also the tensioners spins...

    Risers - think I caught this just in time?

    Just changing the risers out on the boat I bought a couple of weeks ago. It’s a 2005 dry joint system which looks original! I can see what looks like the start of moisture running down the inside (tiny rust spots) in the soot - unless that’s normal from moisture in the exhaust? My question is...

    Mercruiser MPI - How Intelligent is the ECM?

    What parameters would the ECM/ECU adjust on a 4.3MPI if the thermostat was stuck open and the motor therefore running cold at around 100deg or less (rather than the usual 160ish)? I guess it would richen the mixture, but what else like timing, reduced power as engine not up to operating temp...

    4.3 Carb v 4.3MPI

    Is the MPI really 25hp more powerful that the carb or is it just marketing? Any other real advantages of one over the other? Starting / economy etc? Has anyone owned both and care to share their opinion please?

    4.3MPI Risers

    Looking at a 2005 Regal with a 4.3MPI, the broker doesn’t know when the risers were last changed. Looking at the picture (and EPA sticker) are these likely originals from 2005? Also they look a bit questionable at the rear side?

    Mercruiser 4.3mpi Tach

    Hi my Temp Gauge and Tacho are both not working / moving on 2005 Regal with 4.3MPI motor, both are Faria branded. The tacho stays at 1,000RPM with ignition on or off / motor running or not. The Temp gauge moves a tiny bit when ignition is switched on but stays at bottom even when motor is warm...

    Alpha 1 Gen 2 drive shaft seal?

    Hi, just reassembling my lower into the upper housing and noticed a shiny area on the shaft that’s on show - should there be some kind of seal here perhaps or is this OK? I removed the lower from the boat first so not sure if it was already this way. The lower unit is fully engaged and bolted...

    Mercruiser 4.3 Vortec running hot on one side

    Got a strange problem with differing water flow and temp between left and right hand side of engine. Motor has been stored for a long time, drained antifreeze. Lots of crap brown water came out of blue block drains. Now running clear and reinstalled them. After a min or so of running the right...

    Mercruiser 4.3 carb weep

    Hi I have a slight leak between the two nuts on the fuel pipe as they enter the carb. Can you use a small amount of plumbers tape between these nuts to stop it or should I look elsewhere / tighten further?

    Power Steering Pump thread?

    Does anyone know the thread / diameter of the flared hose that screws into the Power Steering pump on a Mercruiser please? I need to buy a barbed fitted so I can loop it back to the return on the pump for testing purposes out of the boat. It’s a 1998 Vortec 4.3.

    Mercruiser 4.3 Vortec Backfire and no start

    Hi guys, quick update on the testing of my motor this weekend. I built a test rig out of a crate and tried to start it, it turns over but doesn’t sound like it wants to start and then I had a couple of big back fires. Believe they come out exhaust. I know I took the distributor out whilst...

    Can run a 4.3 Merc without the alternator belt?

    Hi looking to test my 4.3 tomorrow out of the boat on a test stand. Is it OK to run it without the belt attached (I have the single belt connecting alternator, power steering pump to flywheel and water pump)? Reason I ask is the power steering reservoir is drained and I didn’t want to run it...

    Mercruiser 4.3 removing oil from bores?

    Hi, I’m just being a 4.3 out of long term storage (19yrs!) I squirted a couple of shots of engine oil into each plug hole to help with initial turn over - the motor is now free and turning over with good (albeit high, due to the residual oil) compression. The motor spins over freely on the (new)...
