I have tested spark compression and fuel line up to the pump. Ping is intermittment, Ford 2nd level scratches its collective head. Now I find out the foam air filter has disintegrated and that's why the motor doesn't run right anymore. The tech checked with Ford. But now it didn't work again. I had to pay to get my boat having lost all of June. Bought new so I would not have any interruptions with reliability.
Issue found, bad float sensor and bad high pressure fuel pump. In June 2016 the motor quit like it ran out of gas. Most often, you will definitely see the majority of our listings are from eBay. I bought it with the perception that it was basically still a new boat! Shoot a touch of starting fluid in one plug hole, replace plug and fire away. Within 1 week after registering my Mercury, I received a recall notice letter from Mercury on the fuel pump. It always dies after 1 min running now. There was one bad plug.
Also put a gas treatment in the tank. As soon as in water it bogs downs. The tech said it's the carb. The most-reported problem is also with the for. Turn ignition switch on and off several times. Try the same thing with the cap off the tank eliminates a vapor lock. In order to overcome this rep Mercury rebadged engines, painted them grey, and gave them the named Mariner which would denote a saltwater theme.
Most kits are pretty simple. For example: an anticipated fuel problem, can sometimes actually be ignition related, or even compression related. It's a quality motor if your concerned at all. It will be brought to a repair shop later this month for more extensive testing. Despite the problem arising during the warranty period, Mercury refuses to compensate me for the repairs that have now totaled over 40% of the original price of a new engine. Original review: July 31, 2017 Although a while ago it would appear no lessons have been learned by this shocking company. Very satisfied with the results.
Usually just a couple gaskets, an o-ring or two, and a new needle and seat. It does not mean that the normal service and maintenance items are only designed to last 12 months, it means that your authorised dealer can attend to any tune-up, service or warranty issues to ensure you get maximum pleasure and carefree running out of your engine. My 1988 40hp Mariner runs like a watch. Not sure whether to chuck good money after bad. In the last couple days all of a sudden it will allow me to throttle up all the way, but it will only go about 15 mph.
If all cylinders now fire, replace both packs, as there is a problem in the bias circuitry. Switched to Amsoil two stroke oil, this gem of an engine runs clean and smooth. Then it started bogging down after accelerating. Ran well on land with water hose attached. Now we have replaced the injector a third time and replaced the wiring harness and you guessed it. I pulled gas line, no fuel again!!! Needless to say I'm extremely disappointed with Mercury Marine. They later came out with their own cowlings and paint scheme to match the Bayliner branding.
If the timimg varies, replace the packs. The one thing i saw about the sea foam is to fill the filter. Original review: May 22, 2018 Mercury Verado 300. Very good engine, at least that one is. Or, did it have it before putting away for the winter? If there is a sudden or fast drop in voltage right before this miss becomes apparent, the stator is usally at fault.
Across the board if all out reliability is the name of the game then its Honda or Yamaha, if reliability and performance then Evinrude e-techs. When the dealer took off the hood on the engines we noticed salt over the entire block on both motors. It's also very hard to start it normally have to pull more than 20 times. On 4 cylinder engines, the bias circuit is internal therefore, the only way to varify proper operation of the bias circuit, is to index the flywheel and check timing on each cylinder. It has been out of the water in the shop for more time than it has been in use.
In late 1999, we started our first message board. Once Merc acquired Mariner, the mariner product line basically became Mercurys with different cowls. Replaced steering column ignition housing flange switch. Of course, Mercury has them on back order, and aren't going to ship any for at least two weeks, if then, so I'm losing a month or more of the summer due to a crappy design that cannot be fixed even after at least half a dozen re-designs of their fuel delivery module. If this fails, pull the carbs, clean them, put in new gaskets and go from there. I will try the seafoam tonight and if that doesnt work, ill look into if it only uses a certain amount of cylinders at diff rpms. I know Mercury, who also makes Mariner, has some models that only run on one or two cylinders until a certain rpm, then kick in the others.
Guilty until proven innocent I guess. Low voltage symptoms are weak fire or weak erratic firing of cylinders. We keep one at the shop for just such a occasion. Sometimes, infrequent use may not alert you to minor maintenance requirements that could eventually lead to starting or reliability problems right in the middle of your valuable recreational boating time. I said it has been cleaned by a technician. Restarted and tried forward, was surprised when engine revved up and ran my 2007 Lund 1950 Tyee Magnum right up the launch ramp.
