    Mercury 90HP 4 Stroke 2003 Impeller Change

    Thank you Texasmark. I answered my own question by cracking it open. Lower unit lubricant does not drip out and it is indeed sealed from the water pump area. Replacing the impeller went smoothly. I put it in forward gear, removed the LU, cleaned up around everything and followed the...

    Mercury 90HP 4 Stroke 2003 Impeller Change

    Good morning. I ordered an impeller kit, new housing, etc. to do a full water pump change in the lower unit. When I purchased the boat, the stream seemed a little weak, plus, I have to squeeze the muffs to get water flow. Last Fall I changed the oil and gear lube for winterization. Now...

    2003 90hp Mercury 4-Stroke Carburated

    Thank you for the pointers. I was planning on draining the bowls. We have long winter layups in the upper Midwest. I didn’t touch the yellow painted screws.

    2003 90hp Mercury 4-Stroke Carburated

    So in summary….I removed and cleaned the carburetors, changed the fuel filter, drained the gas and put in fresh non-oxy with a concentrate of sea foam. I have a new squeeze bulb and silver hose on order because it’s my understanding the lining deteriorates over time, and I did find black prices...

    2003 90hp Mercury 4-Stroke Carburated

    Good morning. I just picked up slightly used 2003 Pontoon with a clean 2003 90hp Mercury 4-Stroke. We had an exceptionally long Winter so it's been laid up in storage since last October. We just put it in this weekend and it wouldn't hold at idle and would die. I pulled the boat, pulled the...

    High Performance Gear Lube Color - Bravo 3

    Sorry about the late response. I've been away for a week. Yes, I did drain all the fluid and I also ran the fresh stuff through it while warming up the engine to change the oil. Seeing as the marina replaced all of the bellows last year, I am going to have them look at it - give it a...

    High Performance Gear Lube Color - Bravo 3

    Yup - fresh water and a 3 month boating season. Bellows looked fine but had it done anyway. Neat.

    High Performance Gear Lube Color - Bravo 3

    Drive was pulled last fall. New bellows, trim senders, gimbal bearing, shift cable, and u-joints were all replaced last Fall. I added the shower last Spring. Prior, the bellows were only 6 years old. I stay up to date on all maintenance, but I don’t do outdrives. I leave that to the marina...

    High Performance Gear Lube Color - Bravo 3

    I guess I’ll take it in next Spring to have a pressure test and figure out what’s wrong. She’s tucked away for the Winter. I was hoping the bright green was a good sign. B.O.A.T. s

    High Performance Gear Lube Color - Bravo 3

    I had the marina do it last year because I had the u-joints replaced however I couldn’t find one of the gaskets. It doesn’t mean it wasn’t on there but I did it Friday night in the dark. I also checked to make sure it wasn’t stuck inside either hole. I used two new gaskets this time. Thats a...

    High Performance Gear Lube Color - Bravo 3

    I recently put a drive cooler on my Bravo 3 because its seemed every season my drive lube would be almost black. We do a lot of cruising between islands and sometimes I'll be on plane for 45 minutes. Anyway, I drained the fluid for winterization and this is the color (see pic). This season...

    Alarm Going Off for Mercruiser 350 Mag MPI

    Any news?

    Alarm Going Off for Mercruiser 350 Mag MPI

    I just recently posted a thread. I had what I thought to be an alarm, but what was happening was I was stalling out and then the ECM was going through it’s restart process by sounding a single alarm, and then the fuel pump goes on. At higher rpms it would beep, and then the rpms would lower...

    2005 5.0 MPI shutting down and restarting

    In closure, so if people search engine like I have for the past month and couldn’t find “closure” for the same issue, it turned out to be the Crankshaft Position Sensor. It was available at Napa for $75. Try that before dumping $2k on a new ECM.

    2005 5.0 MPI shutting down and restarting

    Update : I have been running at multiple rpms for 45 minutes and no stalling. I have yet to put a load on it.

    2005 5.0 MPI shutting down and restarting

    S/N 0W037286 I posted on another thread about a month ago which is a no-no, however I was hoping to have the solution solved and yet no joy. My engine, once it starts to warm up, is stalling or shutting down, then the restart beep comes on and the fuel pump. I’ve had two different service...

    Mercruiser 5.0 mpi starter noise just as engine starts 2011

    My apologies for revising an older thread. I know the community likes to start fresh, however I find myself with the exact issue with a replacement API 10099hd. It worked fine for about 6 starts and then started with the squealing. I am assuming it’s the bolts. It just seems odd that it...

    5.0 MPI runs for a minute, beeps and shuts off

    Figured it out. Plugs 7 & 5 where switched and my IAC went out at the same time. Not bad for a 16 year old IAC. Switched the wires and had a spare IAC - all good.

    5.0 MPI runs for a minute, beeps and shuts off

    Mercruiser 2005 5.0 MPi 0w037286 This a new phenomenon. I replaced the starter, manifolds risers and elbows, plugs, wires, and thermostat. Now when I start it, it runs for a minute, beeps and shuts down. Then I go to start it again and it beeps and shut down sooner. Seems a little rough at...
