    Can you pressurize the gear lube system?

    Hi, Trying to track down a gear lube leak. Have determined that the drive unit itself is fine as it held 10 lbs of pressure overnight. Haven't seen any gear lube inside the boat, so am pretty sure the leak is either on the exterior side of the thru hull fitting or in the tube that runs...

    Lower Unit Lube Leak

    2004 Alpha I Gen II Had a lower unit lube leak last boating season (had to refill the resevoir several times over a couple months). Removed the unit, built pressure tester, and tried it last night....held 10 psi overnight. Bought a vacuum (brake fluid) tool today and will try to adapt that to...

    Lower Unit Pressure Tester - fitting to L/U

    Trying to build a lower unit pressure tester, but am having difficulties with the fitting that screws into the fill/vent hole on the lower unit. I'm using the fitting from an old lower unit oil pump, however, it is a two piece fitting such that you can spin it without the entire hose and pump...

    Pressure Testing Lower Unit

    Alpha 1 Gen 2. Had to top up resevoir a couple times this summer...so pulled off the drive and built a pressure tester per someone's previous post. After putting in approx 11 lbs of pressure, it all leaks out in about 30 seconds. Will try to confirm tonight that my tester connections aren't...

    IAC Valve - Carbon Build Up

    2004 5.0 Mercruiser MPI Engine was surging/stalling at idle last fall (after a long run at idle towing someone in). After winterizing, I took off the IAC Valve and discovered the hole in the bottom of it was totally blocked by carbon. Cleaned it up and reinstalled, but didn't start the engine...

    Could Exhaust Leak Cause This?

    2004 Mercruiser 5.0 MPI Been stalling at idle and when trying to shift. Happens more so when cold....after running up the lake and warming up, it seems to idle better, but not great. New plugs had no impact. Took it to the mechanic who hooked it up to the diagnostic scan tool....everything...

    Mercruiser 5.0 EFI Idle Surge When Cold

    Hi all, 2004 Mercrusier 5.0 EFI (sorry, don't have the serial # handy). Last year I had to rescue a guy and his family after they flipped their tin boat while pulling a tuber (gotta wonder what, if anything, he was thinking!). Had to pull in his overturned boat at idle....took about 30...

    140 Looper High Idle

    1986 140hp Evinrude Idle was fine for the last use in the fall. Did have a stalling on acceleration problem, but discovered a kink in one of the carb fuel delivery hoses so assume that was the stall issue. Pulled the boat out of winter storage today. Replaced the kinked carb hose and started...

    AC Delco Spark Plug 41-932

    Hi all, Want to replace the plugs in my 2004 Mercruiser 5.0 MPI. Currently have AC Delco 41-932. Called my local auto part store and they advised that they only have two left and can't get anymore because they were discontinued and replaced by plug # 41-993. Last time I bought something at...

    Surging When Cold

    Hi all, 2004 Mercruiser 5.0 MPI with Alpha Drive. A couple weeks ago, I witnessed a family of four (2 adults 2 kids) capsize their tin rowboat with a 9.9 hp while towing a tube with two more kids on it!!!!Gotta wonder what they were thinking. Anyway, ran out in my boat to retrieve them and...

    Upper Drive Unit Leak

    2004 Mercruiser 5.0 MPI with Alpha Drive Replaced the impeller a few weeks ago and immediately thereafter developed an gear lube leak that required me to top up the lube monitor every few days. Assumed that it was the o-ring between the upper and lower gear drives that got misaligned, however...

    Lower Unit Lube Leak

    Hi all, 2004 Mercruiser 5.0 MPI, with Alpha Drive. Replaced the impeller last week and ran it for the first time on the weekend. Realized my lube monitor level is dropping rapidly while the boat is running (drops about an inch after 1.5-2 hours of operation). I'm guessing that the o-ring...

    Looper Carbs

    1986 Evinrude 140hp Been fighting a fuel delivery problem for a long time and want to purchase a used set of carbs for my looper. My question is....will a set of looper carbs from a 1993 140 fit on my 1986 140? Thanks, Brew

    Looper Bogs only when Hot

    1986 Evinrude 140 looper. Been chasing a bogging problem for a looooong time. Carbs are clean (extremely clean), new carb kits, new fuel pump, new fuel lines, good spark and compression, no air leaks that I can find in the fuel system. When the motor bogs you can get it to recover by bumping...

    Prop for Alpha Drive

    Just purchased my first I/O. Mercruiser 5.0 MPI with Alpha Drive. Prop is currently an aluminum with a few dings, so have been looking at replacing it with SS. I've just realized that some props have solid hubs and others rubber. What are the pros/cons of each? Do I have to use one or the...
