    One of the mods here has a YouTube video that explains it well. If you do it EXACTLY the way he explains it, you'll sort it out

    Mercuiser 180 temperature issue

    I did. Since I did, I haven't taken it out for a test with a load on it. Like I wrote earlier. My point of this post is I was hoping to find someone who has had a similar situation to compare it to.

    Mercuiser 180 temperature issue

    Raw water pump is new. Not just the impeller, the entire housing. Heat exchangers are 4" I'm kinda stumped at this one but like I wrote, I didn't run it after the CLR and the rod cleaning. I only idled the motor at the dock for a half hour or so and it didnt raise over 140 F (better than before...

    Mercuiser 180 temperature issue

    Looking for some feedback here. I'm having issues with my portside motor increasing in temperature upon load. I noticed it was running warmer than last year and was 20 degrees higher than my starboard motor. When I got out of the harbor and throttled up the temp jumped from 160 to 180 in 2...

    Guess the part

    Looking at that I'm guessing electrolysis had a hand in that. I'd be willing to also bet the transom mount is probably sheite as well

    470 coolant pressure test

    Thanks for the chart. I'll bump up the pressure tonight and retest. I only went to 7 psi because the cap is usually rated to 12lb or so. I figured 7 was a reasonable number. I did re do the test this morning and it held the 7 psi for at least 2 hrs or until I left for work. I left it...

    470 coolant pressure test

    Greetings, Looking for input on how long to expect a cold block to hold pressure testing for a coolant leak. I pressurized the system at around 7psi and it bled off about 1psi after an hour or so. I'm assuming that it's acceptable. Anyone have any input?

    Speed sleeve for Cam seal /470 required items

    Yes. I got nothing out. Chances are the antifreeze is from the leaky riser gasket I just fixed. I'm thinking it may have weeper through the #4 cylinder over the winter. I did find some antifreeze in it when I was preparing to initially start up this year. I'm just looking for the part numbers...

    Speed sleeve for Cam seal /470 required items

    Hello there, Just did an oil change and believe my Cam seal on my 470 might be leaking (kinds milky oil) Does anyone have the part numbers of the speedi sleeve and seals needed to do the job?

    Transom mount mercathode with twin i/o

    Not sure if this belongs in electronics forum or here, so apologies to the moderator in advance. I have twin alpha one drives that have a peculiar issue. One drive gets galvanic corrosion way more than the other (port gets it and starboard gets minimal) I noticed that my transom mount...

    Osco risers for 470 motors

    I'm trying to figure out if an osco 0879 riser can be used on one of my 470 motors. I picked one up on eBay to keep as a spare (got it for $100) but realized after I purchased it theres two different ones,one for aluminum and one for cast iron manifolds. Does anyone know if they are...

    Alpha one U joint groove/leaking at the end of every season

    Anyone have any past experience using a speedi sleeve on one of these U joint yokes to stop it from leaking? Every year I have been having issues with one of my drives leaking oil because it's got a bit of a wear on the shaft where the seal rides. It will hold 15psi for a week on my stand in...

    3.7L 180HP (470) fuel consumption

    Question for anyone who might know, Roughly what's the fuel consumption per hour (@3400 rpm) on a 470 Mercuiser? Specifically the one with the 4 barrel carb I know there are many factor at play here but I'd believe someone might have a rough guestimate or benchmark. Anyone?

    470 mercuiser milkshake

    I did an oil change on my starboard 470 and to my surprise I pumped out a milkshake. Bummer.... I had ran the engine to warm it up before pumping out the oil and it ran fine. I just noticed the reservoir was out of antifreeze prior to starting it. It took about a pint to fill it to the top...

    Winterizing heat exchangers

    Question for all you freshwater cooled dudes. When you winterize your engines, do you leave the drain plug out of the heat exchangers or do you drain them, then re install the drain plug? Where I live it's been unusually cold for this time of the year. I was worried that they might be half...

    Toilet pump out (not) Carver Montego

    Trying to figure out why my head won't pump out. It had a manual pump that appears to look like it brought the waste up to the pump out port on the side of the boat where you would hook the suction pump up to. It was dry rotted so I bypassed it and hooked the waste pipe directly up to the port...

    Exaust pipe change 180 (470)

    I'm gonna ask a stupid questions that I know the answer to but want to see if MAYBE someone else has done it. I suspect that my port exhaust pipe is leaking. I have the tell tale signs of water in the bilge when I run the engine on muffs and can see some crud next to the pipe where it appears...
