Fuel Issue, '93 Merc 60HP

8 posts in this topic

I ran into a problem with my '93 Merc 60HP last night. It ran great till it used up all the fuel in the primer bulb (bulb got soft). Then, I had to squeeze the bulb till full, and it ran fine again till it used up all that fuel. It was a bit of a challenge to drive down river while pumping the bulb every 5-10 seconds!

Other than that, it runs great at all speeds--idle to WOT. It is run off of a portable 6.6 gallon tank. The vent was open. I even tried it with the gas cap off, just in case the vent somehow got plugged.

I plan on picking up a new fuel line and primer bulb. Does that sound reasonable? Alternatively, is there a fuel pump that could be going out?

I'd start with the hose and bulb Ralph... if that doesn't cut it, then I'd buy a fuel pump rebuild kit (pretty easy to do) and that should take care of your issues.

Is there any troubleshooting technique that would help me distinguish bewteen a hose/bulb problem and a fuel pump problem?

I would recommend getting a real Merc brand fuel line and bulb from a dealer, not one of those cheaper versions from big box store. The extra money is worth it.

Good luck.

Not off hand... if you had an air leak you might see fuel leaking out of a pinhole... depending on where the leak (and where it's getting air from).

I suppose you could disconnect the motor side of the hose, and prime the primer bulb and see if it stays firm... that would eliminate the hose, but not the fuel hose on the motor from the connector to the filter.

In my opinion, I think it's the fuel pump, but it doesn't hurt to check the easy stuff first.

I changed the primer bulb, checked the fuel pick-up, and tightened all connections last night. Ran it on the muffs in the driveway for a half-hour and all seemed fine. I guess the real test will be on the water, though. Should be able to get it on a lake tomorrow evening.

If I do need to do the fuel pump, how easy is that? It is pretty accessible, or will I need to do some major disassembly? Do I just buy a rebuild kit (looks like they're about $10)? Anything to look out for?

Glad to hear it.

The fuel pump is pretty easy - no major engine disassembly... pull the pump off the side of the block and rebuild it on the bench, then put it back together.

    • My wife and I like to float down the Crow from Rockford to the Mississippi. Hardly anyone on the river except Bald Eagles. Found some nice chicken of the woods mushrooms last summer.
    • Trump got the information from Nunes. Nunes heads the House intel committee, but Nunes also was a member of Trump's transition team. Nunes then fed information to Trump (information that apparently nobody else on the intelligence committee has) about incidental observation of Trump and his transition team (a team that includes Nunes himself). 
    • A better question would be are you right?  Even the articles you link to don't really support your "most likely" assertions so you have to resort to everything is a lie as evidence, like Donald's twitter, and anyone that doesn't believe your alternative facts is an Obama luvin' librul. 
    • What projects have you worked on? Big or small lets see um. Anything, guns, boats, cars, Decoys.    I had fun reworking a few old Harley Golf carts. Didn't have any digital before shots to post. The carts I got were in very bad shape. Had to do a lot of fiberglass body work on them and some mechanical work to get them running. Just used boat seats as I didn't want to throw a bunch of cash at reworking the old seats and one cart had no seats at all when I got it. I took all the big chrome front bumper and bag bars off and glassed over the holes. Everyone had cracks in the front nose cones and rear ends. Not perfect but fun. Top picture is one of the nicer ones I started reworking.
    • Do you have any thoughts about what state you're heading to for this?  CO is draw only but there are lots of decent options available with 0 points. MT had leftover tags which is good because you missed the deadline already. WY has options you could draw. ND has passed. NM passed. UT not a good option with no points I think. ID may have some options but not certain. SD and NE may have some good options but I've never hunted either.   That's some basic info on states. Once you pick a state and get a tag it's really not complicated for the most part. Get elevated, glass up a muley, bed him, sneak in him without being smelled it seen, shoot him!   My son and I just found out we drew ND muley tags this year so we're pumped about that!
