    Trim Tilt switch

    This is 60 years old. Don’t think you’ll find parts. And honestly not sure why you would want to. Could be trim, could be tilt. Either way it probably hasn’t worked for 40 years.

    Mercruiser 4.5l low vacuum, WOT 4350 and higher fuel consumption

    Ha Ha, No longer a tech. Parts counter 18 hrs a week as my retirement hobby. While I do have access to some confidential information, I only post things that I will freely give to customers that walk through the door. Just please understand that we don’t help DIYer’s when we are busy with...

    Trim Tilt switch

    Old "nail" style drives had the trim switch at the top of the gimble ring. It's not an Alpha. https://forums.iboats.com/threads/miscellaneous-mercruiser-information.323278/

    Outdrive oil level- dipstick or vent plug?

    Should be in the middle of the flat area of dip stick. Vent is the correct level. The dip stick is in the middle of a hollow shaft that only has a very small hole to let lube in/out, so let it settle for a few minutes.

    Mercruiser 4.5l low vacuum, WOT 4350 and higher fuel consumption

    This is a 2016 warranty return engine sold by MCM at auction in 2018. Yes, check gear ratio. What you've posted so far looks to be over propped. Fuel pressure looks low. Should be 50-54 psi with no vacuum on the regulator. Are you testing per the manual? But we are looking at "snap shots" of .1...

    Pro xs stalls at idles/ Sluggish acceleration

    Did you find the cause of why the first powerhead went bad and correct it? Have you replaced the fuel, oil and air filters? Tried a new set of spark plugs? Check TPS, don't replace it! test it. idle - 0.17–1.05 VDC / WOT - 3.76–4.64 VDC Next is fuel/air pressures. air = 95 ± 1 psi Fuel/air...

    Exhaust bellow slipped off

    MerCruiser tech support has been recommending super glue for exhaust bellows that slip off. Works for me, I use the gel version.

    dp-c shafts and gears still available?

    As @Scott Danforth mentioned, the hole in your transom won't work for anything else without fiberglass work.

    Merc 250 Verado Fuel increase

    We don't do many Simrad setups, but do install many Garmin and Hummingbird MFDs. It is common for MFDs to read a slightly different voltage. Anything 0.5v and under is nothing to worry about. As always, the voltages you see on the scan tool and DMM are all that really matter. I have long felt...

    Merc 250 Verado Fuel increase

    No Lemon Law for boats. There are some consumer protection laws, but in 40 years I have heard of very few successful cases and never seen one that worked out in the customers favor. But I'm not sure why you be upset Mercury made a couple of special tools for this job? They aren't needed, they...

    Merc 250 Verado Fuel increase

    Paint coming off in sheets is bad prep. @alldodge has silver gear cases. this is a special $62 a can catalyzed paint. And special prep. Once you start, you have less then 6 hrs to use it up. This means the 4 coats need to be put on every 1/2 to 1 hr. Mercury pays 3 hrs. So I could guess that...
