    Service manual for 7.5 HP

    Thanks, knowing the year helps. There are several parts discontinued but it looks like iBoats has what I think I need to get it running. Still looking for a free manual but not a big deal if I have to order a Clymer or Seloc.

    I don’t know if I would call it copper.

    Service manual for 7.5 HP

    I’m looking for a service manual for a Mercury 7.5 Hp 2-stroke outboard. I have no idea how old this motor is. Mercury tells me the serial number isn’t valid which is making it difficult to know what parts to order. Serial number on the tag is 6431074. Someone lied to a buddy and told them I...

    4.3 Mercruiser fuel supply issue

    There wasn’t any indication of internal damage when the belt stripped. The manual says the valves can hit the pistons if the timing isn’t correct. Stripped belt pretty much guarantees the timing being off. However, when the pulley broke, the seal on the other cam let go for some reason.

    4.3 Mercruiser fuel supply issue

    This could be hull style, props and/or the driver’s knowledge but the manager and I somehow ended up crossing the lake at the same time last year. He was in a 270 HP Cobalt 200 (Volvo Penta) and I was in the Sea Ray 210 with a Mercury 150 HP EFI. I got on step faster and walked away from him for...

    4.3 Mercruiser fuel supply issue

    We got the boat back from the shop. The bill was about $3700 for a fuel pump change. The engine work is done and lake tested but I still have to crawl in there to put the hull back together. Season is over so no rush.

    5.0 GXi oil extraction

    I filled the boat with oil and returned the boat to the dock on November 2nd so the guy who winterizes the 6 I/O boats in the fleet could do whatever it is he does to get antifreeze throughout the motor while in the slip. The pictures helps. Now I have an idea what to look for. I didn’t expect...

    5.0 GXi oil extraction

    I think the $2K inspection camera is only 640 pixels. Mine is anyway. I bought it to inspect aircraft cylinders years ago but I use it for nearly everything I when I have a need to see something in a tight space. The specific problem with getting the oil out was it kept sucking air whether...

    5.0 GXi oil extraction

    Mirror and flashlight sounds easier to me. Especially since I don’t have a “stick” to hold my phone and the mirror has a telescopic handle so I don’t have to hang head low and stretch my arm down there hoping I get a picture of what I need.

    5.0 GXi oil extraction

    Thanks for the tip. I will have to crawl in there with a flashlight and mirror or videoscope and have a look.

    4.3 Mercruiser fuel supply issue

    Is it supposed to a plain copper washer or a true crush gasket. If the latter, I may have one out in the hangar.

    4.3 Mercruiser fuel supply issue

    I ended up turning this one over to the local Mercruiser service center for lack of tools/equipment to remove the outdrive and raise the motor shortly after my last post. I don’t have what I need to do it “right”. Apparently there were some missing parts because they called me asking about a...

    5.0 GXi oil extraction

    I can’t speak as to oil change frequency before 3 years ago but every 100 hours or once a year since I got involved with the maintenance. The ski boats see just under 100 hours a year since they started bringing in more pontoon boats. The 2 outboard ski boats are more popular than the I/O boats...

    5.0 GXi oil extraction

    Should be correct. I didn’t measure either but it looks exactly like the one in the boat I returned to the lake yesterday. Boat is a 2015 model with 1029 hours so who knows? But I fail to see how it could affect my ability to remove oil from a boat sitting level on the trailer. How could not...

    5.0 GXi oil extraction

    I checked the oil level before attempting extracting the oil. The dipstick showed full but I am sucking air. I have only managed to remove about 2.5 quarts after an hour last night while the oil was warm and 2 hours this morning with the oil about 50 degrees. I am using a hand pump vacuum...

    4.3 Mercruiser fuel supply issue

    Yeah, I won’t own a newer I/O for myself. It’s bad enough dealing with it for pay. The next one in line has a Volvo Penta needing a trim pump. Not a terrible job but a lot of blind groping around while laying on top of the motor trying to get it installed and hooked up. Rumor has it this outfit...

    4.3 Mercruiser fuel supply issue

    I am bad about using proper terminology. Did not know better most of my life and bad habits die hard. It is an I/O. I have no idea what disconnecting the drive entails so I guess I will be searching the manual and youtube for that too. I let the local service center do engine removals, gimbles...

    4.3 Mercruiser fuel supply issue

    I did get the cover off. Accidentally knocked the bottom loose then used brute force to twist it out. Didn’t help much. One fuel line I can see needs a key(?) to remove so a trip to NAPA tomorrow for that. The line on the regulator is a flare nut. I have SAE flare nut wrenches but none in...

    4.3 Mercruiser fuel supply issue

    Pulled the cooler hoses and got some free movement but now it is hung up on the oil dipstick tube in a tighter spot than it started so I still can’t get the cover off the pump. I hate to give up the income but this thing is getting really close to finding its way to a mercury shop.

    4.3 Mercruiser fuel supply issue

    “If you disconnect the return line coming from the pump back to the fuel filter (arrow pointing in on filter head). Seal off the filter head and seal off the return line. Have gauge on fuel rail and turn key on/off, maybe a couple times to build pressure. It should go above 43 psi but try not to...
